Review of Compass 31

Basic specs..

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can enter even shallow marinas as the draft is just about 1.40 - 1.50 meter (4.59 - 4.89 ft) dependent on the load. See immersion rate below.

Compass 31 is typically equipped with an inboard Volvo Penta engine at 36.0 hp (26 kW), which gives a max speed about 6.8 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank which is made of fibreglass has a capacity of 155 liters (40 US gallons, 34 imperial gallons).

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Compass 31 is about 176 kg/cm, alternatively 988 lbs/inch. Meaning: if you load 176 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 988 lbs cargo on the boat it will sink 1 inch.

Other Important Factors to Consider

small boat compass

What is a marine compass?

A marine compass is referred to as one of the simplest but very valuable instrument to have at hand whenever you traverse open waters. At present, nearly all boats are equipped with electronic navigation system; however, it is still vital to have a compass with you so that it will be less likely for you to get lost on your destination.

This device comes with a dome-shaped bulb compass that is mainly utilized by boaters. It is also furnished with a dial that revolves on a pivot. Many kayakers connect these units to the front deck of a kayak either with the use of a tie-down mechanism, bungee cord or use it permanently.

Each compass comes with a line on its glass which is known as the lubber line. This is utilized to illustrate your direction on the compass card. The compass card is the card that rotates and indicates, North, West, South, East etc.

How does it work?

These devices are typically filled with liquid. The liquid comes with a reducing effect on disruptions brought about by the vessel’s motion in rough waters. In the same way, the compass card is affixed on top of the magnetic needle mechanism.

This is evenly balanced on a needle point, hovering and is capable of swinging around so it could coordinate with magnetic north. Please be guided that the reading is captured from the fixed lubber line on the compass’ body. It is worth noting that the lubber line is directed in the direction of the vessel’s head for taking over on a given bearing.

What are the different types of marine compasses?

Gyrocompass . Most huge ocean-going vessels use this type of compass and it is considered as a vital component of their navigation system. This works by controlling the gravity force to a gyrowheel in order for the wheel axis to frequently explore the north to south line.

It is recognized for its sophistication that typically unveils true North in place of magnetic north. Basically, it remains uninfluenced by external magnetic fields.

Card Compass . This is primarily utilized for boats and ships. It is distinct from other types of compasses since it makes use of a fixed needle, and it depends on a maneuvering compass card for directional interpretations. In addition to this, since the maneuvering card takes in much of the movement of a ship or a boat, it is more straightforward to interpret as compared to a needle compass.

Prismatic Compass . This is prominent for being a very advanced instrument that is specifically designed for highly precise navigation. It is important to note that the prism sighting arrangement enables users to interpret the bearings of the compass while observing remote objects.

Magnetic compass . This makes use of a maneuvering needle or moving card to detect magnetic North.

Electronic compass . This commonly provides bearings on a numerical interpretation. In general, they provide precise readings and come with several unique features and these consist of the option to reserve bearings in the memory and its capability to alert users if he’s losing his way.

Notwithstanding, these are not highly suggested for map work. Also, since they call for a power source, at times, reliability becomes a serious concern.

Fluxgate compass . This does not come with moving parts and utilizes electricity to intensify the directional signal and it also utilized coils of wire.

GPS compass . This makes use of a number of satellites that identify the location. This pinpoints true North.

Best Marine Compass: Going the Right Way Cheaply

compass 31 sailboat review

If you're serious about sailing, you know that a reliable compass can make all the difference. I've tested many compasses and read tons of reviews of other sailors, and here are my absolute favorites.

On this page:

Which marine compass should i get for my sailboat, why i picked the ritchie navigation explorer, important factors when buying a compass, what should you look for in a quality compass, some quality compass brands to consider.

I recommend the Ritchie Navigation Explorer (click to check current price on Amazon ) - This compass is competitively priced, good looking, simple, reliable and rugged. Bracket mount (which I like). Also called the B51, it's the all-round best compass for most people. Best bang for the buck.

This is the compass I currently have and it's my all-time favorite. It's incredibly accurate - just like its predecessor, which was also a Ritchie.

If you don't want a bracket mount, here are some alternatives:

  • Ritchie S-53 Explorer (click to check current price on Amazon ) - Surface mounted, making it ideal for smaller boats - still a well-priced, reliable, and good-looking compass. Also has a night light.
  • Ritchie F-82W Voyager (click to check current price on Amazon ) - Flush mounted, and one of the most beautiful compasses you can get for a reasonable price. Best quality. Has power damp, meaning it's more stable. Is said to be extremely accurate. You could also take a look at the Ritchie FNW-203 Navigator. It's even more beautiful (but way too expensive for what you get in functionality, in my opinion).
  • Ritchie Navigation Globemaster (click to check current price on Amazon ) - Binnacle mount: it looks amazing. But oh man, that's an expensive compass.

I know, it's all Ritchie here - but what can I say? They provide very good value for money. Other compass brands tend to get pretty expensive, and the folks at Ritchie just really deliver. I never needed something else, to be honest.

I had an older model before (I'm not quite sure which one) and just wanted the same one, but new. I like the bracket mount, it provides more stability, and it's easy to install and adjust.

  • Accurate compass, even when distorted by magnetic fields
  • Has corrector magnets, allowing you to calibrate it
  • Has dampening and gimbal for stabilization
  • Has a night light - light isn't too bright
  • Easy to mount (simply fasten two bolts)
  • Analog, so reliable
  • Ritchie Compasses come with a 5-year warranty - even if I can use this compass for just five years, that's money well spent
  • Bracket mount gives you more mounting options
  • I like front reading cards
  • If it breaks, it can most likely repair it myself

Cons: it is a pretty big compass, but it will still fit most small sailboats. The housing is plastic, but it's durable.

There are two major factors two consider: mounting and size.

Mounting method

Choosing the right mounting method for you makes all the difference. The three most common mounting methods are:

  • Bracket mount
  • Flush mount
  • Surface mount
  • Binnacle mount

Bracket mount - the compass rests in a bracket. Bracket mounts can be mounted in the helm or on deck. I prefer this mounting method. They are easy to install and keep the compass card at the right viewing angle. Flush mount - the compass rests inside the dashboard. Less easy to install, but man ... it looks good. Surface mount - the compass sits on top of the dashboard. Very easy to install and looks pretty decent for most compasses with a low profile. Binnacle mount - the compass has it's own casing. Looks great and all, but takes up a lot of space and is a lot of work to install properly.

Choosing the right size is just as important. Most smaller to mid-sized compasses are between 4-5 inches wide. You don't want a huge compass in a tiny helm, but you also want to be able to read it easily. The method of mounting also plays a large role here.

For small sailboats (under 20 ft) I'd recommend getting a small surface-mounted compass.

  • Accuracy - there's no way of knowing the accuracy upfront, except by relying on brand reputation and other people's experience.
  • Reliability - a compass is your most important navigation tool and should continue to work in all conditions .
  • Dampener - high-quality compasses have a dampener under the card - this keeps them from wiggling on sea.
  • Corrector magnets - you'll find the corrector magnets inside the compass housing. You can use them to adapt the compass to the magnetic fields from the electronics and materials on your boat.
  • Gimbal system - a gimbal system makes sure your card stays level.
  • Design - it has to look good. You'll be staring at this thing A LOT.
  • Durability - a compass should be able to withstand the weather and last you a decade.
If you want a detailed look at how a boat compass works, you can read my Beginners Guide on Boat Compasses here (new tab)

I admit, I'm a fan of Ritchie. But there are other reputable brands that make great compasses out there:

  • Ritchie - well-known and reputable brand
  • Silva - Garmin is best known for producing quality marine electronics, but they also make pretty decent marine compasses under their brand Silva.
  • Seattle Sports - not a well-known brand, but they have produced accurate compasses in the past.

Although there are some great looking compasses out there, most of them are just too expensive in my opinion. Ritchie seems to have fixed that problem by providing a great quality compass with good warranty at a very decent price. If you're looking for a simple and clean compass, and don't want to pay top bill, I recommend the Ritchie Navigation Explorer (click to go to Amazon ).

What to Look for in a Sailing Compass

There are various factors you should take into consideration when attempting to buy a sailing compass. You would likely want to read user reviews and potentially test one out yourself to get a feel for what you need.

In addition you should also narrow down your sailing goals to determine what is going to work best for your situation. Buying a sailing compass simply because you think it looks cool is not going to help your situation out on the water.

Size of the Compass

In my experience you should aim for a sailing compass that has a large diameter. It needs to be able to fit properly onto your dashboard at the helm so that you have and easier time reading it.

If it is large enough you can read the numbers easier when the boat is in rough conditions. It does not necessarily have to have a backlight but that would help especially at night.

Various Mounting Options

Depending on the type of boat and the sailing compass you choose it might have different options for mounting it. Various mounting options exist for those that want to mount it a certain way.

Space on the Dashboard

This installation is simply on the dash of your boat if applicable. You will need to cut out and fit a section of the dash in order to keep it secure and it makes it permanent.

Flat Surface Areas

Installing on the surface is likely the easiest and quickest since you can simply place it and be done. A surface mount can either be flat somewhere at the helm or horizontally at the best spot. This also prevents you from having to cut out a section of the dash.

Using Brackets

If your sailing compass comes with brackets this will allow you to place anywhere you desire with some installation required. A bracket mount will typically allow you to move the compass slightly to get a better read and is ideal for placing in vertical spots.

Mounting it Flush

A flush mount installation is where you cut a hole in your dash and expose just enough of the compass to read it. Some sailing compasses are more attractive looking when you install it this way but it does take a little more time than standard surface installations.

Binnacle Mounting

Choosing a binnacle mount is another option that is referred to as a “little house” for the compass. This helps keep it out of the elements or sunlight and are typically larger.

A majority of the sailing compasses you see on the market have a backlight and it is a handy feature if you are in lower light conditions. You will likely need to have it close to a power supply for a lot of these but some come equipped with a slight illumination already to make it easier to read.

Various Types of Dials

There are a few dial options to consider when selecting your sailing compass. Each one could appeal to you based on the way you prefer to read it.

Direct Dial for Upright View

A direct dial has the lubber line in an aft position and are best suited for helms that are closer to eye level when sailing. It is recommended that you have plenty of experience reading this type of dial since it requires some knowledge beforehand.

Dial with Flat Card

A flat card dial has to be read while you are standing or sitting in a seat above the helm since it features a horizontal face. The lubber line is forward so you would need to have the right angle when looking at it.

Hybrid dials are likely what you are thinking which is a mix between direct and flat. These allow you to read the compass from nearly any direction. These are best if you are needing to see the direction from any part of the boat and if you are newer to reading a compass.

Your Knowledge

If you have never used a compass before it will likely take a slight learning curve to get used to it. Consider purchasing one that you can either read from any direction or has simple but precise markers in order to get an accurate reading. Sailors that have plenty of experience might be able to read any compass no matter the quality.

How Does a Sailing Compass Work?

A compass is an essential tool for your boat to help guide you safely during any event at sea. This is especially important because if your power fails on your boat you can use your compass to help navigate back to safety.

How it Operates

Beneath the compass card is a tiny magnet that keeps north and south in line with the help of the Earth’s magnetic field. The compass is encapsulated with a fluid to help keep it stable upon moving on the boat. These are typically an analogue compass but some digital ones do exist usually as a handheld version.

Deviation Process

Deviation is a term used to describe when a compass is thrown off of its accurate reading due to other magnetic influences or too much metal interfering with it. You will need to read the manual or check with a qualified professional to help get it back in check.

Various Styles

Your boat will likely need a specific compass to make it worth the investment. As mentioned a binnacle compass is best for when the view is above and it is likely mounted on the wheel.

Smaller boats that utilize tiller steering are best suited with bulkhead mount that are located at the front of the cockpit. These also generally help with determining the angle of the heel the boat is experiencing.

In other words you should conduct the proper amount of research to best fit your needs. Your budget and boat type will play a crucial role in determining the best one. Your sailing experience can also make an impact on the buying process to help find the best tactical scale on the water.

A Better Electronic Compass

  • By Dave Powlison
  • June 20, 2023

We first looked at Velocitek’s Prism compass in 2019 and found a lot to like: big, easy-to-read numbers, cut-acrylic lenses that allow the numbers to be easily seen in any daylight situation and not get wonky when viewed through polarized lenses, and at just under five ounces, probably the lightest small-boat compass out there.  So, when we learned a new version was in the wings, we had to see what could possibly have been improved.  

In appearance, the New Prism is identical to the original except for one detail—a USB port on the back, sealed with a half-inch diameter plug that can be screwed in or out with a coin. Out of juice after a long day on the water?  Plug it into your computer or a wall brick, and in about six hours you can go from zero to full charge. Most times, you don’t even need to be at 100 pecent since a full charge will last more than 48 hours, so you probably won’t even need six hours of charging. No more setting the compass out in the sun for hours after racing, hoping the clouds don’t roll in before it’s recharged. 

“The USB is more of a sure thing,” says Velocitek’s Charles Swanson. “Cloudy days don’t affect it, and it doesn’t matter if the compass is tucked up in the shade under the boom.”  With this setup, the solar panel is now just a battery-extending backup.  

The other big difference is inside. The New Prism now houses the same, patented, solid-state geomagnetic sensor found in Velocitek’s top-of-the-line ProStart instrument. Two big advantages of this upgrade, says Swanson. “This magneto-inductive sensor is not influenced by temperature changes and is inherently free from offset drift. This means that the factory calibration remains valid indefinitely and in all conditions. ”

More importantly, the new sensor, combined with the more powerful charging supplied by the USB connection, allows a dramatically improved refresh rate—the number of times the screen is updated—going from the earlier Prism’s once a second to four times a second. Want to see it in action? Go through a tack and watch the numbers change. Undetectable lag time.  

Ease of use?  One button positioned on top of the compass does everything. That should put a big smile on the faces of those who have struggled with multi-button processes on various other electronic devices. Press the button and the left screen says “BAT” and displays the battery level on the right screen. Shortly after, it automatically switches to compass mode. And that’s all there is to it, unless you want to set the damping mode, done by briefly pressing the button again.  Toggle through one of three damping levels by tilting the compass. This was the trickiest part of the compass to use, as you have to press the button again at the exact moment the desired damping level appears. Miss that moment and you’re probably onto another damping level. Not a big deal though, as this is something few would often adjust. Turn off the power by holding the button down for about three seconds. Easy-peasy.

For some, the one hesitation about the New Prism is the lack of a timer. The folks at Velocitek don’t apologize for that. After all, their goal was to create a straightforward, easy-to-operate, top-level compass—nothing more. Perfection embodied. And that’s just fine with a lot of sailors. For instance, in some classes, it’s impractical to have a timer and compass in one unit, such as Nacra catamarans, which mount the compass on the bowsprit, or 49ers, which carry the compass forward of the mast. That’s a pretty inconvenient reach to change modes. Others gravitate to a single-use instrument because of a reluctance to be without compass readings in the starting sequence. Yes, you can toggle between modes, but how many of us have found ourselves locked out of one mode or the other at that critical time, often because we accidentally pressed the wrong button or we held it down too long?  

This compass doesn’t meet the needs of everyone, but if you’re looking for a fail-safe instrument that will give you quick and precise readings as well as eliminate concerns about staying charged, it’s definitely worth considering. $579.

Marine navigation has never been more accurate with TurnOnSport Boat Compass. Accuracy has always been one of the most critical issues with marine compasses, but TurnOnSport’s compensators easily settle this concern.

One of the highlights of TurnOnSport is its East-West and North-South compensators that minimize external influences on the marine compass. This leads to a more precise direction, making it one of the most reliable and in-demand compass brands in the market today.

The compensators aren’t my only favorite thing about TurnOnSport. I also like that it’s dependable day in and day out. At night, its incandescent light makes the device visible and readable. There is nothing to worry about when the dark sets in.

And if you’re concerned about the rugged marine conditions, this brand is definitely up for the tough times. The compass’s made from ABS plastic, which is waterproof and corrosion-resistant.

Despite its hefty size, the device remains lightweight. Installing it yourself will be a breeze. The compass comes with two EVA stickers and two screws, so mounting is never a challenge. Just look for the sweet spot, stick it up or screw it and you’re done.

You also do not have to worry about exposing the compass to too much sunlight as it has a movable cover for shade. Whether it’s a big boat or a kayak, TurnOnSport is your dependable marine compass.

  • Reliable East-West, North-South compensators for accurate direction.
  • With incandescent lights for nighttime viewing.
  • Lightweight, waterproof and corrosion-resistant.
  • Easy setup using freebie stickers or screws.
  • Has sun cover to avoid too much sun exposure.
  • Can be used in various marine boat types.
  • Size may be a bit bulky.

Reliable utility and superior accuracy are what Ritchie Navigation Explorer Compasses are known for. With over a century of experience in the marine industry, Ritchie Navigation products remain top producers of navigational compasses for commercial and recreational boats. So, what’s up with their Explorer compasses? Find out in this review.

One of my pet peeves with compasses is how unreliable they can be. But this 2.75″ surface mount compass has what it takes to be considered a trustworthy product. I love that the makers reinforced the device with a triple cup sapphire jewel and a toughened steel pivot where every micrometer matches to a tee.

As a result, the device operates quite smoothly and locks on rather quickly even when subjected to extremes.

To be more specific about it, this device sports High Gauss Magnets customized for different compass specifications. These magnets seek and lock to magnetic north, so you know you are always right on track.

Another must-have utility for any boat compass is compensators. You can tick that box off as this compass has those. It has solid, built-in, non-interactive magnets that act as compensators for correction and accuracy. Moreover, you will get to enjoy its nighttime internal green illumination using a 12V power light.

  • Accuracy guaranteed with its triple cup sapphire and robust steel pivot.
  • Uses High Gauss Magnets that point to magnetic north.
  • Its solid compensators reliably correct deviations.
  • Green light illumination for nighttime navigation.
  • Adjustment rod may rattle over long-term use.

Tired of an unreliable compass? Odowalker Electronic Marine Digital Compass is one of the few top-of-the-line brands that hold on to promised accuracy and aesthetics. It is highly functional and straightforward, giving you spot-on directions without a lot of fuss.

If you’re a sailing enthusiast as I am, then you’ll definitely find this device to be quite a dependable buddy at sea. The device is sturdy and is made for tough times using high-quality ABS material.

Nighttime sailing can also be extra challenging for sailors, as poor lighting impairs much-needed visibility onboard. So I like that Odowalker had its compass built with an incandescent bulb light to illuminate the compass. This makes the device readable even at night.

Another thing I like about Odo Walker is how easily you can adjust the declination sheet. Thanks to its adjustable brackets, managing the compass’s position relative to the viewer’s angle can be done swiftly. I did not have to stay in one spot to get a good view of the compass.

Moreover, this compass is not just for marine use. It’s also best suited for cars, trucks, and other land-based automobiles. Odo Walker is truly one of the most flexible compass devices you can get out there. The device is available in black and white colors with a neat-looking design.

  • Sturdy and reliable, made from high-quality ABS.
  • Nighttime illumination using built-in incandescent bulb light.
  • Manage compass’s position easily using its adjustable declination sheet.
  • Flexible device; can be used on land-based automobiles.
  • Neat design coming in black and white color options.
  • Lacking instructional guide.

compass 31 sailboat review

The right marine compass for me comes from the reliable company DETUCK. I love this dash mount marine compass because I can use it night and day thanks to its night lighting feature and red indicator line.

The magnetic declination easily identifies both east-west and north-south directions, so I never get lost in the middle of the ocean as it improves the compass’s accuracy. I have come across several compasses that come with this feature, but not all of them are as easy to adjust as this one.

For a light traveler like me, I always choose to bring lightweight objects. I am glad that this compact compass only weighs 2.7 ounces. It is light on both my hands and in my pocket. Plus, it is also easy to mount as it comes with double-sided tape and screws that you attach to the dashboard.

  • Ideal for both night and day usage with its lighting feature and indicator line.
  • Comes with magnetic declination that accurately locates direction.
  • The magnetic declination is easy to adjust.
  • A lightweight and compact compass.
  • Easy to mount due to the double-sided tape and screws.
  • Needs frequent configuration of the compass’s horizontal level.

compass 31 sailboat review

If you are looking for compasses for boats, then you have come to the right place. Few things beat the Ritchie Nautical Compass, among other sailing compasses. This device is easy to read thanks to its direct reading dial. Plus, your night trips will become a breeze with its built-in green lighting.

The Ritchie compass is made with Sapphire jewel and toughened steel pivot. Besides that, it boosts sturdiness with high-temperature composite. You do not want to miss its classic finish and design, either! When I bought it, I immediately knew that this one oozes exquisite quality just by looking at it.

One feature that I like about this compass is the impressive directive force magnets because not all sail boat compasses are blessed with this feature. It gives me a quick heading lock-on so I can have a more precise direction anywhere I go. You know you are in good hands with RITCHIE because they offer a 5-year warranty on all items.

  • This flush mount boat compass is easy to read with its direct reading dial.

  • Composite, sapphire jewel, and hardened pivot for optimum durability.

A busy sailor like me wants a compass that is quick and easy to read. I am grateful that I found this compass. Upon purchase, SeaTurtl served as an easy-to-read marine compass that perfectly fits on my standard-sized deck.

The hood’s adjustable feature gives protection to my favorite compass, especially when not in use. It also prevents glare when I use it on the sea. This is one of my ideal features since I hate the blinding glare which may cause accidents. It is a dangerous thing that we tend to overlook.

  • Features four modifiable cords that secure the compass in place.
  • The SeaTurtl Mountable Kayak Compass is quick and easy to read.
  • The adjustable hood protects the overall product and also prevents glare.
  • All compass features stay true even after years.

We are now at the last but not the least product in this article, and I will tell you why I reserved this one for you. I got this bulkhead mounted compass when I was about to have a long trip at sea, and this dash mount compass never disappoints. It is a flush-mount compass, too, so you can easily put it on top of almost any surface, including kayaks.

Plus, this compass is way different from other models in terms of quality and reliability. The BRUNTON compass has five-degree graduations for optimum accuracy. You know you are going in the right direction with this tool.

Save your troubles with this easy-to-read compass with its direct reading disc that makes this feature possible. It gives spot-on directions with its reciprocal bearing, even when facing giant waves at sea, so you would not have trouble figuring out your location.

  • This flash-mount compass attaches to almost any surface.
  • Also a bulkhead mount device.
  • Comes with five-degree graduations for optimum accuracy.
  • The product is easy to read thanks to its direct reading disc.
  • Gives accurate directions with its reciprocal bearing.
  • The included screws are too sharp.

We all want to make our buy worthy. That’s why everyone should be equipped with some info regarding marine compasses. So, what are the two important things that you must keep in mind? Well, first is the mounting method.

If you choose the correct mounting method before buying your compass, you will notice how it makes all the difference. There are different mounting methods, but I will just introduce the four common ones and exclude less common types like the overhead marine compass. They are the bracket mount, flush-mount, surface mount, and binnacle mount.

In a bracket mount, the compass usually rests in a bracket. You can mount this type on helms or decks. It is also easy to do, and you can have the right angle right away, which is why it is loved by many compass users.

Next is the flush mount. In this type, the compass lies inside the dashboard. It comes with a challenging assembly, but I can guarantee that the quality and visuals that this mounting type offers are out of this world.

The surface mount is where the compass sits on top of the dashboard. Just like a bracket mount, it is also easy to install. If you opt for a decent-looking installation, then you should go for this one.

Lastly, the binnacle mount. Just like the name says, a binnacle-mounted compass comes with its own case. It also looks decent and classy, but this mounting type may be bulky and takes up a lot of space. It also needs a lot of work, just like a flush mount.

After knowing the mounting types, I know that you already have your favorite in mind. It is time to go to the next thing that you should consider – the size. You would not want a bulky compass attached to a tiny helm. Besides that, the right size allows you to read the direction quickly and easily, even after installation.

Remember that smaller to mid-sized ones can range from 4 to 5 inches wide. Small sailboats, usually under 20 ft., are better suited with a small surface-mounted compass.

dash-mount-marine-compass

A bracket-mount compass usually comes with a mounting bracket. Some compasses do not come with a bracket mount, but there are times when you can convert one type of mount to another — for example, using a bracket to convert a flush mount to a bracket mount.

If you do not want to have a bracket mount, you can opt for Ritchie Explorer, Voyager, or Navigation Globemaster models.

Marine compass adjustments can be a piece of cake or a headache. But the general rule is to head zero degrees using the compass while disregarding the heading. After that, you should turn exactly 180 degrees and adjust the compensator. This will take out half the overshoot or undershoot. You can then repeat the steps on 90 to adjust the fore compensator.

To know if your compass is running accurately, you should observe these things. Put the compass on a non-magnetic flat surface.

Afterward, you should turn it in a clockwise and counter-clockwise direction. If the compass is accurate, the needle should act like a match stick that floats in the middle of a basin of liquid that you twist.

Calibrating a compass is one of the most challenging parts for me. I know that you can eventually get used to it, but the quality of a compass also plays a part. Choose a compass that delivers accurate direction and does not require constant calibration or tapping. It will save your time a lot.

Choose the best marine compass that comes with your preferred mounting type. By doing so, you can install something that you can actually handle. If you are a starter, choosing a bracket or surface mount is a good idea.

Boat Compass Buying Guide

There are many things you need to look out for when purchasing a boat compass. After all, you don’t want to end up with a product that doesn’t show true directions. Here’s everything you need to know.

Compass Size

According to experts, as a rule, always choose a compass that has a large diameter. It should conform with your dashboard or helm to fit properly while also increasing readability. This feature can be a lifesaver when there is a lot of turbulence or when a storm is making the boat too rocky. If your compass does not come with illumination, a bigger dial will make it easy to read in the moonlight or under a flashlight.

Mounting Options

You also have a choice when it comes to the placement of your compass. Pick out the type that you feel will best suit your needs.

This is a model that can be installed on the dashboard of a ship or a vehicle and are mostly direct read dials that have to be kept in a vertical position to work properly. You will need to cut out some parts of the dash panel to properly install this boat compass.

Surface mount

These compasses can either simply be placed on a flat surface or installed horizontally. They are ideal for when you don’t want to cut out the dash or when you have a compact helm and come in all types of dials like direct-read, flat, or hybrid.

Most experts prefer compasses that come with brackets, as they allow tilting of the compass for better readings, but they are primarily suited for vertical surfaces. These come in all types of dial options.

Flush mount

This is another mounting option that requires you to make a hole on the surface of the dash. It gets installed into the hole so that only the surface of the compass is visible. These kinds of compasses are available in direct reads or hybrid dials.

Binnacle mount

Another type of surface mount compass is the binnacle mount model. These have longer bodies, as the compasses are large, and all come in flat card dials.

Almost all marine compasses come with LED lighting that needs to be connected to the power supply. This is because illumination makes reading the directions easy on a compass, whether you are traveling during the day or on dark, stormy nights. Certain compasses come with their own illumination that is either red or green-hued.

Some compasses come with adjustable shields that help protect the compass from sunlight to not cause glare. This helps increase readability even when the light is too bright, or the boat moves too much.

When it comes to boat compass dials, there are quite a few options. Here is all you need to know.

Direct-dial

Direct dials are for upright views where the lubber line is at the aft portion. These conical-shaped dials are perfect for helms where the boat compass is close to eye level. Generally, this type of dial is for expert sailors, as they know just the right way to read it.

A flat card dial comes with a horizontal face, so you need to be standing up when checking the compass. The lubber line is at a forward position, which is well suited to helms because you are mostly standing straight while piloting the boat. If you have a luxury boat with high seating, a flat card compass would also work well for you.

Hybrid dial

Hybrid dials are a mixture of direct read and flat card compasses. Also known as the combi-dial, the hybrid is widely available among boat compasses from Ritchie Navigations. What is so interesting about hybrid dials is that they can be read from above as well as from the front. This makes for an excellent and easy read because taking notes of the directions will not be an issue whether you are sitting or standing.

This is another important thing you need to consider when purchasing a boat compass. If you are a seasoned sailor, you will be able to read all kinds of dials and compasses. However, if you’re new to sailing and haven’t had much experience taking readings from compasses, you will need to get one that has clear, precise markers and a simplified read. This way, there will be no chance of getting confused about which direction you want to go.

A: Whether you are a professional sailor or a beginner, a compass is essential. If you don’t have a compass, the chances of getting lost are high, it can cause great distress, and might also lead to some kind of accident. So be sure to always sail or go out on the sea with an accurate compass.

A: Calibrating a compass isn’t too difficult. You start by putting the compass to zero and then turning it 180 degrees. Then adjust the athwartship compensator in such a way that one half is over or undershoot. Repeat at 90 degrees, all the while adjusting the fore/aft compensator.

A: Very much so. The compass can break, its glass can crack, the plastic can melt, or the housing could leak. After some time, the fluid in the housing can change colors, although this only happens after a long time of use. Most compasses from good companies last a long time without getting any kind of damage. Generally, it’s a good idea to check out reviews before investing in one.

A: This depends on what manufacturer you buy from. Some companies give a bracket mount so that installation is easy, while others only come with double-ended tape or with a stand of their own that can be placed on a plain flat surface. If you have specific needs, be sure to ask the seller whether or not a bracket comes with the compass.

COMPASS 31: A Refined and Abbreviated Composite Autonomic Symptom Score

David m. sletten.

Associated data.

To develop a concise and statistically robust instrument to assess autonomic symptoms that provides clinically relevant scores of autonomic symptom severity based on the well-established 169-item Autonomic Symptom Profile (ASP) and its validated 84-question scoring instrument, the Composite Autonomic Symptom Score (COMPASS).

Patients and Methods

We assessed the internal consistency of COMPASS using Cronbach α coefficients based on the ASP of 405 healthy control subjects recruited and seen in the Mayo Clinic Autonomic Disorders Center between March 1, 1995, and March 31, 2010. Applying a simplified scoring algorithm, we then used exploratory factor analysis with orthogonal rotation and eigenvalue calculations to extract internally consistent domains and to reduce dimensionality. This analysis was followed by expert revisions to eliminate redundant content and to retain clinically important questions and final assessment of the new instrument.

The new simplified scoring algorithm alone resulted in higher Cronbach α values in all domains. Factor analysis revealed 7 domains with a total of 54 questions retained. Expert revisions resulted in further reduction of questions and domains with a remaining total of 31 questions in 6 domains (COMPASS 31). Measures of internal consistency were much improved compared to those for COMPASS. Following appropriate weighting, this instrument provides an autonomic symptom score from 0 to 100.

COMPASS 31 is a refined, internally consistent, and markedly abbreviated quantitative measure of autonomic symptoms. It is based on the original ASP and COMPASS, applies a much simplified scoring algorithm, and is suitable for widespread use in autonomic research and practice.

The Autonomic Symptom Profile (ASP) is a well-established questionnaire designed to comprehensively evaluate the severity and distribution of symptoms and the autonomic functional capacity of patients with autonomic disorders. It comprises 169 questions and assesses 11 domains of autonomic function. 1 It was first described by Suarez et al 1 in 1999, continues to be used routinely at Mayo Clinic and many other institutions around the world for a comprehensive assessment of autonomic symptoms and functions, and continues to serve this purpose very well.

Using a limited set of 84 clinically selected questions, we have used this questionnaire to generate a Composite Autonomic Symptom Score (COMPASS). 1 The questions comprising this instrument address 11 autonomic domains with 72 questions ( orthostatic intolerance , 9 items; secretomotor , 8 items; male sexual dysfunction , 8 items; urinary , 3 items; gastroparesis , 5 items; constipation , 4 items; diarrhea , 4 items; pupillomotor , 7 items; vasomotor , 11 items; reflex syncope , 5 items; and sleep , 8 items) and an additional 12 items to generate 2 validity scores (an understatement index comprising 6 questions and a psychosomatic index comprising 6 questions). 1 It has been validated and used extensively by our group and selected others. 1-7

However, over the years, we have identified several problems with this instrument that have resulted in concerns about supporting this tool for use by other institutions in spite of broad national and international interest:

  • 1 The scoring algorithm of COMPASS is highly complicated and requires computer analysis for score generation. The complexity and ambiguity of the extraction process has resulted in even experienced users obtaining inconsistent scores.
  • 2 Completion of the ASP, even if limited to the questions relevant for COMPASS, is time consuming.
  • 3 The questions within the domains assessed using COMPASS have not been evaluated for internal consistency.
  • 4 Several questions included in the original COMPASS instrument have over time been identified to be less meaningful or redundant for scoring autonomic function and symptom severity.

A redesign of this instrument to a simplified, more time-efficient, statistically more robust, but still comprehensive tool to assess and grade symptoms relevant to autonomic function that can find broad application in research and clinical practice is therefore needed. The specific aims of this study were (1) to develop a simplified and more user-friendly scoring scheme for questions that comprise COMPASS and (2) to critically assess current questions and domains and use state-of-the-art statistical methods guided by clinical judgment to develop an updated, concise, and statistically robust stand-alone tool that provides a clinically relevant general score of autonomic symptom severity with meaningful subscores for individual autonomic domains.

Study Participants

A total of 405 healthy control subjects who were recruited and seen in the Mayo Clinic Autonomic Disorders Center between March 1, 1995, and March 31, 2010, were asked to complete the ASP after informed consent was obtained. The study was reviewed and approved by the Mayo Clinic Institutional Review Board.

New Scoring Scheme

A new, simplified autonomic symptom scoring scheme was developed that follows a homogeneous pattern of scoring throughout the instrument. Simple yes or no questions were scored as 0 points for no and 1 point for yes. Questions about a specific site of symptoms or symptoms under specific circumstances were scored as 0 if not present and as 1 if present for each site or circumstance. All questions regarding the frequency of symptoms were scored as 0 points for rarely or never, 1 point for occasionally or sometimes, 2 points for frequently or “a lot of the time,” and 3 points for almost always or constantly. All questions regarding the severity of symptoms were scored as 1 point for mild, 2 points for moderate, and 3 points for severe. When assessing the time course of a symptom, we scored 0 points for responses such as “gotten somewhat better,” “gotten much better,” “completely gone,” and “I have not had any of these symptoms,” 1 point for “stayed about the same,” 2 points for “gotten somewhat worse,” and 3 points for “gotten much worse.” The scores for changes in bodily functions depended on the individual question asked. For example, “I get full a lot more quickly than I used to when eating a meal” was scored 2 points and “I get full a lot less quickly than I used to” was scored 0 points, while the answer “I sweat much more than I used to” was given 1 point and “I sweat much less than I used to” was scored 2 points.

For the new scoring system, we opted to eliminate scoring of questions previously comprising the syncope domain because of its vast overlap with the orthostatic domain and the questionable relevance of reflex syncope for the assessment of autonomic deficits. 8 We also eliminated questions about male erectile dysfunction for scoring because of the low specificity of erectile dysfunction as an indicator of autonomic nervous system impairment and the difficulty of a universal scoring system with questions that relate only to one gender. 9,10 Furthermore, we opted to combine the diarrhea domain and the constipation domain into a single lower gastrointestinal domain.

Statistical Approach to Assessing the New Scoring Scheme

Comparisons of the current scoring algorithm using the questions originally selected for COMPASS with the previously described new scoring algorithm using all suitable questions from the ASP was performed by calculating Cronbach α coefficient as a measure of internal consistency for items comprising respective domains as they are grouped in the current version of the ASP. 11,12 A Cronbach α coefficient of 0.70 or higher was considered acceptable.

Factor Analysis and Approach to Content Reduction

In order to identify internally consistent question domains and to reduce dimensionality, ie, the number of questions retained, unbiased exploratory factor analysis of items was performed with orthogonal rotation. 11-13 The eigenvalue rule was used to extract factors, retaining only factors with eigenvalues greater than 1. The resulting model was confirmed by inspecting the corresponding scree plot, which is a visual representation of where the sharp decline in factors levels off, at which point factors become less relevant (even if their eigenvalues are >1). Only items with factor loading of 0.40 or greater were retained, and ambiguous items (ie, items loading on more than one factor) were eliminated.

The resulting set of questions and domains was then reviewed by 2 autonomic experts (P.A.L., W.S.) to accomplish the following 3 goals: (1) to decide on redundant content in order to allow for further reduction in the number of questions, (2) to retain clinically important questions that were previously eliminated on factor analysis, and (3) to assess for clinical appropriateness of the grouping of questions into domains based on the factor analysis.

Final Assessment of Content and Design of the New Instrument

After clinical review and revision of questions and domains to be included in the final symptom score, another calculation of Cronbach α coefficient values was performed to assess for the internal consistency of the new instrument. To allow for the calculation of a weighted total score, the maximum raw score for each domain was determined and each domain was assigned a weight factor based on our current perception of the importance of domains for reflecting autonomic failure, so that the minimal weighted score for the instrument equals 0 and the maximum weighted score equals 100. All the analyses were performed using SAS version 9.2 software (SAS Inc).

Of the 405 recruited control subjects, 166 (41%) were male and 239 (59%) were female. Ages ranged from 8 to 79 years with a median age of 32 years. Race was predominately white (388; 95.8%), and ethnicity was predominantly non-Hispanic or Latino (394; 97.3%).

Comparison of Scoring Schemes Using the Previous COMPASS Domains

The Cronbach α coefficient of previous COMPASS domains ranged from −0.89 to 0.79 using the old scoring system, with only 2 domains reaching a value above 0.70 ( orthostatic intolerance and erectile dysfunction ). Cronbach α coefficient values were markedly improved using the new scoring system, ranging from 0.40 to 0.90, with 4 domains reaching a Cronbach α coefficient greater than 0.70 ( Table 1 ). All domains had a higher Cronbach α coefficient with the new compared to the old scoring system. Cronbach α coefficient calculations stratified by gender showed a similar trend with markedly improved values for both males and females using the new scoring algorithm ( Table 1 ).

Exploratory Factor Analysis

Exploratory factor analysis based on the eigenvalue rule and factor-loading criteria described previously identified 7 factors consisting of a total of 54 questions. Five of these 7 factors corresponded well with the previous domains of orthostatic intolerance , vasomotor , secretomotor , pupillomotor , and bladder , each containing only items that had previously been part of those domains. The other 2 factors grouped questions on gastroparesis and diarrhea as 1 factor (a mixed upper gastrointestinal domain) and questions regarding constipation as a separate factor. The Cronbach α coefficient for these domains ranged from 0.71 to 0.93 and therefore exceeded the acceptable level of 0.70 for each of these 7 domains ( Table 2 ). The previous sleep domain was not identified as a separate factor of internal consistency and was therefore eliminated.

Domains Identified, Cronbach α Coefficients, and Number of Questions Retained Within Each Domain Based Solely on Statistical Measures (Exploratory Factor Analysis) With Factor Loading ≥0.40 a

Expert Revisions and Final Assessment of Content

Expert review confirmed the grouping of items into 7 factors as clinically meaningful domains with content that allows for retaining previous clinical designation of domains. It was believed, however, that retaining a separation between a gastroparesis/diarrhea domain and a constipation domain was not clinically useful, and the 2 gastrointestinal domains were combined, resulting in a total of 6 autonomic domains in the new instrument.

Review for redundant content allowed for elimination of 23 more items. Both experts believed that 5 items that were originally not retained in the factor analysis should be reinstated because of their clinical importance. These factors consisted of questions about changes in body sweating, dryness of the mouth, postprandial vomiting, cramping/colicky abdominal pain, and loss of bladder control.

The remaining 31 items and new scoring method were reanalyzed for Cronbach α coefficient of each domain. Compared to the statistically ideal 54-question set, Cronbach α coefficient values were similar for 3 of the 6 domains, slightly lower but still high for the gastrointestinal domain, and lower (and below 0.70) for the other 2 domains (0.62 for the bladder domain and 0.48 for the secretomotor domain) ( Table 3 ), which was expected because these domains include items with low factor loading that were retained on the basis of clinical importance alone. The Cronbach α coefficient for each domain was still notably higher than those for the original comparable domains within COMPASS. Table 3 delineates the 6 new domains, the number of questions per domain, and the maximum weighted scores of the new instrument. The original ASP is provided in Supplemental Appendix 1 , the COMPASS 31 instrument is provided in Supplemental Appendix 2 , the scoring system is shown in Supplemental Appendix 3 ( Supplemental Appendixes are available online at http://www.mayoclinicproceedings.org , linked to this article), and the weight factors for calculating weighted scores are listed in Table 3 .

Domains and Number of Questions Retained Based on Exploratory Factor Analysis and Clinical Revisions as Used in the Final Instrument (COMPASS 31) a

Using statistical measures and clinical autonomic expertise, we designed a new, refined, and abbreviated composite autonomic symptom score, the COMPASS 31. The need to develop this new instrument arose from problems with the old COMPASS instrument and the critical need for a straightforward, up-to-date, and broadly applicable self-assessment tool that can assess and quantify autonomic symptom severity across multiple autonomic domains.

Since its original description and validation, we have used the original COMPASS in many autonomic research studies and trials. 2-7 It has been an exceedingly helpful addition to our repertoire to assess autonomic nervous system function and to this point remains the only validated instrument assessing multiple domains of autonomic function. Other more recently developed instruments are helpful but are limited to specific domains. 14,15 We regularly receive requests to support the use of COMPASS by other groups and institutions, but for a number of reasons, we have been hesitant to do so.

First, we have seen inconsistencies and frank errors in scoring with this instrument, even among experienced users. There is little doubt that this relates to the highly complicated scoring algorithm that requires dedicated computer analysis for reliable score generation. Second, several questions included in the original COMPASS instrument have been identified over time as less meaningful or redundant for scoring autonomic function and symptom severity. Third, completion of the ASP, even if limited to the questions relevant for COMPASS, is time consuming. Finally, the questions within the domains assessed using COMPASS have never been evaluated for internal consistency.

When developing COMPASS 31, we sought to address each of these concerns. As a first step, we made considerable changes to the scoring algorithm by applying a much simplified, consistent scoring scheme. This new scoring scheme is more user friendly and also resulted in notably improved measures of internal consistency. Using exploratory factor analysis and critical clinical review of all questions included in the original ASP, we identified 6 internally consistent and meaningful clinical autonomic domains. With the exception of 5 questions that were retained on the basis of clinical importance alone, we retained only questions that fulfilled both preidentified statistical and relevance criteria. Redundancies were reduced as much as possible. As a final step, we assigned each domain a weighting factor based on the relevance of each domain for assessing autonomic function, with factors adjusted so that the minimum total score is 0 and the maximum score is 100. The result is an instrument with considerably improved measures of internal consistency across all domains and with an easily interpretable score of autonomic symptom severity.

COMPASS 31 does not include assessment of erectile dysfunction. Some may view this as a shortcoming of this instrument, but we decided a priori to exclude this domain for several reasons. Erectile dysfunction is a common accompaniment of aging, with prevalence rates as high as 52% in 40- to 70-year-old men. 9 Many factors contribute to erectile dysfunction, including psychological, hormonal, vascular, and neurologic factors. Erectile dysfunction as the result of medication adverse effects is common. 10 Although erectile dysfunction certainly may reflect autonomic dysfunction, we believe that because of its nonspecific nature, erectile dysfunction should not be included in an autonomic severity score. These symptoms should be elicited during a comprehensive autonomic symptom assessment via direct patient interview or by using the ASP, which is designed for that purpose. Finally, the old version of COMPASS was associated with difficulties in statistics and reporting of group results because of the difference in maximum scores between genders related to the male-specific extra domain; these problems are now resolved with the new instrument.

Another domain eliminated for scoring was the syncope domain. There was considerable overlap with the orthostatic intolerance domain, and questions related to reflex syncope were not considered to be a meaningful measure of autonomic dysfunction. 8 Questions previously comprising the sleep domain were found to have very low internal consistency and were not identified as an independent domain in our factor analysis. We did not think that retaining this domain could be justified on the basis of clinical relevance alone.

Our previous separation of the gastrointestinal domain into gastroparesis , constipation , and diarrhea domains was not maintained by factor analysis. The analysis suggested an advantage in grouping questions related to gastroparesis and diarrhea into one domain and questions related to constipation in a second domain. We believe that such grouping would be artificial and that the future users of the instrument would be better served by providing a single gastrointestinal domain score akin to the single score for all the other domains. If further discrimination is needed, this could be achieved by review of individual questions.

The COMPASS 31 was developed as a self-assessment instrument of autonomic symptoms and function that is up-to-date, broadly applicable, easy to administer in a short amount of time, and based on a scientific approach. It was designed to provide a global autonomic severity score and domain scores that are both clinically and scientifically meaningful. We believe that these goals have been achieved. Further validation of this new instrument in various autonomic disorders and degrees of autonomic failure is now in progress.

COMPASS 31 is based on the well-established ASP, a comprehensive questionnaire assessing autonomic symptoms across multiple domains. All questions in COMPASS 31 are contained in the ASP. It is, therefore, easily possible to derive a COMPASS 31 score either from the comprehensive ASP or from the 31 selected questions that comprise the COMPASS 31 instrument, depending on the goals of the clinician or investigator. The new instrument is compatible with data previously acquired using the ASP.

We have included the complete instrument and tools necessary for its application and score generation in this publication. It is our hope that COMPASS 31 will be embraced by many autonomic clinicians and researchers as a concise quantitative measure of autonomic symptoms and function and that it will find broad application in clinical autonomic research and practice.

Swinging the Compass

compass 31 sailboat review

You can employ a compass adjuster to swing your compass or you can do it yourself quite easily. There are several ways to do it, but the quickest and easiest is to have the helmsman steer due north (000°C) on the steering compass while another person uses a hand bearing compass to sight along the centerline of the boat while standing at the stern, well clear of any magnetic interference.

Make sure there is no deviation at your chosen spot, by taking a bearing of a chartered transit and checking it on the chart. Note the course steered and the reading from the hand bearing compass, then turn to 030°C and repeat the procedure.

Continue recording bearings every 30° until you have completed a full 360°. Plot the results on graph paper to produce a curve giving the amount and direction of deviation for each course steered.

If deviation exceeds about 6° on any course, employ a compass adjuster to correct the compass.

Hi guys, I am living in Australia, looking forward to buy my first boat. Anyone has experience with an Adams 31? The one I like was built 1984 half-tonner(what does it mean?) I am new to the sailing world, only took a few days sailing lessons and have some small boat experience. All I want is a cruiser for weekends. Any suggestions? Thanks in advance. Jacky  

Jeff_H

Welcome to sailing. Half tonners are a type of race boat designed to race under the IOR, an now obsolete rating rule. While I am not familiar with the Adams per se, the IOR of that era generally produced pretty unseaworthy and difficult boats to handle. Generally they don''t make very good cruisers as they tend to be pretty spartan and are not terribly robust. They are also difficult boats to race requiring comparatively large crews and sail inventories. Jeff  

Thank you very much for your advice. Seems I need to continue my "boat hunting". How about Compass 29? Ever heard of it? Thanks heaps. Jacky  

I think that is an old Farr designed IOR era boat. The 29 is actually a Farr 9.14 which was also built overseas as well. They seem to be pretty nice boats as old IOR boats go. Jeff

Review of Compass 31

Basic specs..

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can enter even shallow marinas as the draft is just about 1.40 - 1.50 meter (4.59 - 4.89 ft) dependent on the load. See immersion rate below.

Compass 31 is typically equipped with an inboard Volvo Penta engine at 36.0 hp (26 kW), which gives a max speed about 6.8 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.

The fuel tank which is made of fibreglass has a capacity of 155 liters (40 US gallons, 34 imperial gallons).

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Compass 31 is 1.77, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Compass 31 is about 176 kg/cm, alternatively 988 lbs/inch. Meaning: if you load 176 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 988 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is Displacement Length Ratio?

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 29m 2 (312 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.

This section shown boat owner's changes, improvements, etc. Here you might find inspiration for your boat.

John Kretschmer Sailing

Ultima was designed by Angelo Lavranos who began his career as a naval architect working for Angus  Primrose in the United Kingdom and then Sparkman & Stephens in New York, before setting up his own business  design office in Cape Town, South Africa in 1975. Lavranos is at least in part responsible for world-class  designs of the S&S Swan 40 and 48. Shortly before we bought the boat I wrote to Mr. Lavranos who  graciously replied “The Compass 47, was built mostly by Compass Marine in the late ’70s & early ’80s in  Cape Town under my supervision. These were a first-class product.”   

The most traveled and popular large cruiser from South Africa, Compass 47 has an interesting  history. Many of the 50 produced were bought and sailed to Europe or the Americas to be sold as a way  to get money out of apartheid South Africa. Virtually every Compass 47 built has crossed at least one  Ocean, and most of them two or more and at least three have circumnavigated. The boat was the class  winner in the ’82 South Atlantic Race and ’85 Beachcomber Race showcasing her speed and stability.

This is indeed South Africa’s most classic and pedigreed big boat. We found Ultima after a three-year long boat search done while working on other people’s boats. When ​ ​ John proposed to us that we start doing some training passages we knew we needed a thoroughbred ​ ​ bluewater cruiser that could sleep at least 6 and found her on the Eastern Shore of Maryland. In similar ​ ​ circumstances to John’s description of finding Quetzal in Sailing a Serious Ocean, his sister, Liz and ​ ​ brother-in-law Trevor had a look at her before we could get there and gave us a helpful assessment. We ​ ​ made the trip up to see her as soon as we could and once we set eyes on her we knew that she would ​ ​ be the perfect boat for us. After several hours going over her and some careful negotiation, we bought ​ ​ her for a steal.

Upon purchase, we knew very little of Ultima’s recent history. She was obviously sailed to the US in the ​ ​ ’80s. We knew from the yard where we found Ultima, she had been sitting on the hard virtually ​ ​ untouched for the last 3 years. The last major work done on her had been the brand new 54 horsepower Yanmar Engine install done in 2015 by the yard. After a brief sea trial with the new engine, she ​ ​ was hauled and there she sat until we found her. The previous owner must have had big cruising dreams ​ ​ to install such a nice engine, but they never materialized. According to the listing, Ultima had undergone ​ ​ an extensive refit in 2010 with the entire electrical system being rewired, heads rebuilt and plumbed, ​ ​ and new bottom paint. It also stated that in 1995 she was stripped to structural glass dried, hand-laid ​ ​ with 3 layers of cloth and polyester resin the barrier coated before receiving 5 coats of bottom paint.

During our time in the yard at Spring Cove Marina, we changed out the plastic thru-hulls for bronze, ​ ​ replaced steering cables, life-lines, standing and running rigging. The rest of the summer was spent ​ ​ painting the decks and bottom, varnishing teak inside and out, replacing headliners and floorboards, fitting new electronics and getting her ready to once again do what she was built for, head offshore and ​ ​ cross oceans.  

compass 31 sailboat review

Ultima, a 1981 Compass 47, was built in Cape Town, South Africa by Compass/Anchor Marine. Ultima is constructed of solid fibreglass with longitudinal stringers and a keel-stepped mast. She features moderate displacement with a long fin keel and rudder on skeg. Dual companionways allow for easy access to a large, protected cockpit and midship deck.

Her bright interior layout is a 3 cabin and 2 head configuration that is comfortable and roomy with long portlights and several hatches that line the cabin top. The Main Salon has a centerline drop-leaf table and straight settee to starboard and U shaped settee to port. There are pilot berths outboard and storage under. The L shaped galley is to port with a walk-thru to the aft cabin to port and head to starboard. Across from the galley is the Nav. station with a third, single berth stateroom next aft on the starboard side. V berth is forward with hanging lockers to starboard and enclosed head next aft to port.

compass 31 sailboat review

2019: We had Spring Cove Marina build a bulkhead at first fitted by PVC tubes and then a custom made stainless steel support arch. We replaced all of the warped plywood coated in vinyl with white PVC sheets custom cut. They are lighter, flexible and if they wet, they won’t warp.

Contest 31 - Offshore reliability?

Capt. Andrew

Recently purchased a 1975 Contest 31. While reading Hal Roth's "How To Sail Around The World", he shared the tale of "Banjo", a Contest 31, that suffered a six-foot tear in its hull during a hurricane (between Bahamas and east coast of US). Boat was abandoned. Sustained 60 knot winds in what were described as 50-foot breaking seas. Have other small Contests, like the 31, crossed oceans?  

Contest 31 I read the same book and also recently purchased a 1980 Contest 31HT. I think the main thing to take away from that portion of Hal Roth's book is that a Contest 31 can take several knock downs from 50+ foot waves and still stay afloat. In fact, I think Roth implied that the excellent construction of the Contest 31 was the main reason the owner, and friends, made it back alive. As you know, the Contest 31HT (there are two versions of the 31HT designed by Dick Zaal and another version of a different Contest 31 designed by different designer) has a small cockpit which is perfect for open ocean sailing. In addition, she is built like a tank - real solid, with flat uncluttered

Compass 47 (Lavranos)

Compass 47 (Lavranos) is a 47 ′ 0 ″ / 14.3 m monohull sailboat designed by Angelo Lavranos and built by Compass/Anchor Marine starting in 1980.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The COMPASS 47 is a popular cruiser from South Africa. Of the 50 that have been built, 7 are cold-molded PLY and the remainder in solid FG. Variations include center and aft cockpits, sloop and ketch rigs.

  2. Compasses: Winners, Losers Abound

    The US Navy thoroughly tested Ritchie's design and found that the new compasses possessed adequate sensitivity and superior steadiness, without being in any way deficient in directive power when compared to an Admiralty dry-card compass. The Navy's endorsement of Ritchie's innovation helped Edward Ritchie secure a U.S. patent.
