505 Sailing: Everything You Need to Know

505 sailboat weight

Short answer: 505 sailing

The 505 is a high-performance sailboat designed for racing purposes. Known for its maneuverability and speed, it features a single trapeze and a powerful rig. This two-person dinghy offers challenging yet exciting sailing experiences, often attracting experienced sailors looking for thrilling competition.

What is 505 Sailing? An Introduction to the Sport

Sailing, an ancient art that dates back thousands of years, has captivated human beings with its sense of adventure and freedom. From ocean voyages to leisurely cruises, sailing encompasses a wide range of activities that cater to all levels of enthusiasts. Amongst the myriad options available in the world of sailing, one particular class stands out for its versatility, excitement, and technicality – 505 sailing.

The 505 class refers to a specific type of high-performance racing sailboat that has gained immense popularity among sailors across the globe. First introduced in the early 1950s by John Westell, this double-handed, two-person racing dinghy quickly became known for its unmatched speed potential and exceptional handling characteristics.

So what sets 505 sailing apart from other forms of sailing? To put it simply – everything! Designed with meticulous attention to detail, these boats are precision-engineered for maximum performance on the water . With their lightweight hulls constructed from carbon fiber or fiberglass composite materials, coupled with a sleek design incorporating a powerful rigging system and innovative features like adjustable trapeze wires and hydraulic jib lead systems, 505 sailboats enable skilled sailors to achieve thrilling speeds while maintaining complete control.

While some may argue that any boat capable of reaching high velocities can offer an adrenaline rush on par with 505 sailing, what truly distinguishes this sport is its emphasis on teamwork and technical skill. Unlike single-handed sailing where the competitor must rely solely on their own abilities, 505 racing demands a dynamic partnership between skipper and crew.

In this thrilling dance on water, both individuals are tasked with optimizing their positions onboard – adjusting sails in perfect harmony based on wind conditions while skillfully manipulating weight distribution through strategic movements. The symphony of communication between skipper and crew ensures each maneuver is executed flawlessly – tacking into the wind at precisely the right moment, harnessing the power of gusts to accelerate when needed, and skillfully navigating tight turns with hair-raising precision.

It is this combination of technical expertise and synchronized teamwork that not only sets 505 sailing apart as a sport but also creates an incredibly rewarding experience for those who choose to take part. The sense of accomplishment derived from conquering the elements and mastering the intricacies of these high-performance boats fosters a deep camaraderie amongst sailors, making the 505 community one built on shared triumphs and mutual respect.

Beyond the excitement of competition, 505 sailing offers a unique opportunity to explore stunning bodies of water around the world. From picturesque lakes to majestic coastal regions, these versatile sailboats are equally adept at gliding across calm waters or challenging turbulent seas. Whether you’re racing against rival teams in international regattas or embarking on leisurely weekend cruises with friends, the 505 class allows you to immerse yourself in nature’s beauty while indulging your passion for adventure.

In conclusion, 505 sailing represents the perfect blend of speed, skill, teamwork, and exploration. It is a sport reserved for individuals seeking a thrilling challenge that pushes their limits both mentally and physically. If you find yourself captivated by the allure of sailing, yearning for an adrenaline-fueled activity that rewards dedication and precision, then look no further than 505 sailing – where every wave becomes an invitation to conquer new horizons.

How to Get Started in 505 Sailing: A Step-by-Step Guide

Sailing is an exhilarating sport that allows individuals to glide across the water, harnessing the power of the wind. One specific type of sailing that has gained popularity in recent years is 505 sailing. This high-performance two-person dinghy demands skill, teamwork, and coordination but offers a thrilling experience like no other. If you’re new to this exciting world and wondering how to get started in 505 sailing, look no further! In this step-by-step guide, we will walk you through everything from acquiring a boat to honing your skills on the water .

Step 1: Research and Familiarize Yourself with 505 Sailing

Before diving headfirst into any new endeavor, it’s essential to conduct thorough research. Get acquainted with the essentials of 505 sailing by reading books, watching videos, and talking to experienced sailors. Understand its history, rules, equipment needed (such as masts, sails, boards), and various techniques involved.

Step 2: Find a Suitable Boat

Now that you have a basic understanding of what 505 sailing entails, it’s time to find yourself a suitable boat. You have two options here: buying or renting a boat . If you’re committed to pursuing this sport long-term or are financially able, investing in your own vessel can be beneficial in the long run. However, for beginners who want to test the waters first or simply prefer not making such a substantial investment initially, renting is an excellent alternative.

When looking for a boat to buy or rent, consider factors such as quality (fiberglass vs. wooden hulls), availability within your area or local clubs/associations where fellow enthusiasts may provide helpful guidance.

Step 3: Seek Professional Guidance

To ensure you start off on the right foot (or paddle!), it is highly recommended that you seek professional guidance or training before venturing out on your own in a 505 sailboat. A certified instructor can help you understand the finer details of rigging, sailing theory, boat handling, safety procedures, and emergency protocols. They will teach you the essential skills needed to master the art of 505 sailing.

Step 4: Practice Makes Perfect

As with any skill or sport, practice plays a crucial role in improving your abilities as a sailor. Dedicate regular time to practice and refine your technique. Find a local club or community of 505 sailors to connect with like-minded individuals who can provide guidance and support along your sailing journey. Participate in training sessions, join group outings, and take part in races if available – these experiences will elevate your skills while fostering camaraderie.

Step 5: Learn from Your Mistakes

In sailing (and life!), mistakes are inevitable and should be viewed as valuable learning opportunities. Embrace setbacks as chances for growth and development. Reflect on what went wrong during a sail, analyze the situation objectively, consult with more experienced sailors if necessary, and work on avoiding similar errors in the future.

Step 6: Dive into Racing

If you’re seeking an adrenaline rush, consider registering for local or regional races within the 505 sailing community. Racing not only showcases your newly honed skills but also allows you to challenge yourself against skilled competitors and gain further insights into strategic maneuvering. Remember that racing is not only about winning but also about embracing competition as a means of bettering oneself.

To conclude…

Embarking on a new adventure such as 505 sailing can be both exhilarating and daunting at first glance. Yet armed with dedication, persistence, proper training, and an unwavering spirit of curiosity – there is no limit to what you can achieve! So dive into this exciting world headfirst by conducting thorough research; finding suitable boats; seeking professional guidance; practicing regularly; learning from mistakes; and eventually challenging yourself through competitive racing. Remember always to stay safe on the water while having the time of your life. Happy sailing!

Mastering 505 Sailing Techniques: Tips and Tricks for Success

Sailing enthusiasts often find themselves captivated by the challenging yet rewarding sport of 505 sailing. A high-performance two-person dinghy, the 505 is known for its speed, agility, and tactical prowess. However, mastering this sailing technique requires not only skill but also a profound understanding of the boat’s dynamics and strategic thinking. In this blog post, we will delve into some essential tips and tricks that can help you navigate your way to success in the competitive world of 505 sailing.

Before we dive into the specifics, it’s important to note that improving your performance in any sport comes down to practice, perseverance, and passion. The same applies to 505 sailing. You must commit yourself to regular training sessions on the water and continually strive for improvement.

Now let’s explore some techniques that can give you an edge over your competitors on a 505 sailboat:

1. Familiarize Yourself with Boat Dynamics: Understanding how your boat behaves in different wind conditions is crucial . Spend time observing how the wind interacts with your sails, centerboard, rudder, and hull shape. By studying these dynamics closely during various scenarios on the water, you’ll gain valuable insights into how to optimize your speed and maneuverability.

2. Balance Is Key: Achieving balance on a 505 sailboat is crucial for maintaining control and speed. As both crew members work together in harmony, distributing their weight strategically becomes essential during maneuvers such as tacking or gybing. Maintaining a balanced position helps prevent capsizing while allowing for quick adjustments when needed.

3. Harness the Power of Sail Trim : Proper sail trim plays a pivotal role in making your boat perform optimally across diverse wind conditions. Start by ensuring your mainsail is set correctly by adjusting both the halyard tension and Cunningham controls accordingly. Pay attention to twist control – it affects overall power and balance. Experiment with different positions for jib lead and sheet tension to fine-tune your boat’s performance.

4. Master Speed Techniques: The art of maintaining consistent speed while sailing is critical for staying ahead in a 505 regatta. Work on refining your techniques of maximizing power through acceleration off the starting line and executing efficient maneuvers around marks. Small adjustments such as easing or trimming sails, weight distribution, and anticipating gusts can make a significant difference in gaining an edge over your competitors.

5. Embrace Strategic Thinking: Successful 505 sailing also involves being able to think several steps ahead of other boats. Anticipate wind shifts, current variations, mark roundings, and any obstacles that may come your way. Keep a close eye on your competition to identify tactical opportunities that you can exploit swiftly and effectively.

6. Communicate Effectively with Your Crewmate: The synergy between the two crew members is vital for success in 505 sailing. Establish clear communication channels to relay information about timing adjustments, sail trim variations, or any other factors affecting boat performance promptly.

7. Analyze Races Post-Sailing: Invest time in post-sailing analysis regularly to understand what worked well and areas that need improvement during races or training sessions. Embrace technological tools like GPS tracking or video recordings to revisit specific instances where you excelled or encountered challenges.

Remember, mastering 505 sailing techniques is an ongoing journey that requires a combination of technical knowledge, physical skills, mental agility, and camaraderie with your crewmate. By devoting yourself diligently to these tips and tricks while continuously seeking opportunities for growth and learning, you’ll increase your chances of achieving success on the competitive waters of 505 sailing!

Exploring the Thrills of 505 Sailing: Why It’s Worth Trying

Have you ever felt the exhilaration of slicing through the water with only the wind to guide you? If not, then it’s high time you tried 505 sailing. This adrenaline-pumping sport combines speed, strategy, and skill to create an experience like no other. In this blog post, we will delve into why 505 sailing is worth trying and why it leaves sailors hooked for life.

To truly grasp the essence of 505 sailing, let’s start with its history. Developed in the early 1950s by John Westell in Great Britain, this cutting-edge design quickly gained popularity for its versatility and performance capabilities. Named after its length of five meters and five centimeters, the 505 sailboat continues to be a class recognized worldwide and embraced by enthusiasts who crave adventure on the water.

One of the most captivating aspects of 505 sailing is its inherent thrill factor. Picture yourself at the helm of a sleek boat soaring across racing waters – that rush is unparalleled! The combination of high speeds propelled solely by wind power gives an adrenaline kick that will leave your heart pounding in excitement. There’s an undeniable sense of freedom as you harness nature’s forces to glide effortlessly through open seas or challenging lake courses.

But it’s not just about speed; strategy plays a crucial role too. Every decision counts when racing a 505 sailboat. From gauging wind conditions and adjusting sail trim to outsmarting competitors during mark rounding, this sport demands acute mental agility alongside physical prowess. It’s like a game of chess on water as sailors carefully weigh their choices while predicting opponents’ moves – all while tearing through waves at breakneck speeds.

What sets 505 sailing apart from other forms of competitive sailing is its unique teamwork requirement. Unlike single-handed boats, such as Laser or Optimist dinghies, helming a 505 requires a crewmate who handles various tasks while onboard. This aspect fosters camaraderie and trust between sailors, creating an unbreakable bond on and off the water. The synchrony required between skipper and crew is a delicate dance that elevates the overall sailing experience .

Beyond the thrilling nature of 505 sailing, it also offers opportunities for personal growth and development.

From local regattas to international championships, there is no shortage of events where you can connect with like-minded individuals who share your passion for this incredible sport. The sense of belonging to a global network of sailors fosters lifelong friendships and a sense of belonging to something greater than oneself.

So, whether you’re a seasoned sailor searching for your next challenge or a newcomer looking to dip your toes into an adrenaline-fueled adventure – give 505 sailing a try. Feel the wind in your hair, embrace the rush of speed, and witness firsthand why this sport has captivated sailors worldwide for decades. It’s time to explore the thrills of 505 sailing because once you do, there’s no turning back – prepare to embark on a journey that will leave you breathless and craving more.

Safety First: Essential Gear and Precautions for 505 Sailing

When it comes to sailing, safety should always be the top priority. Whether you’re a seasoned sailor or just starting out, having the right gear and taking necessary precautions is essential for a smooth and secure sailing experience. In this blog post, we will delve into everything you need to know about staying safe while 505 sailing.

The 505 sailboat is known for its speed and agility on the water, making it a popular choice among competitive sailors . However, with great power comes great responsibility – ensuring your safety depends on being adequately prepared and using the right equipment.

One of the most important pieces of gear for 505 sailing is a personal flotation device (PFD). Wearing a PFD not only keeps you buoyant in case of an emergency but also provides an added layer of protection against potential injuries. Look for a PFD specifically designed for sailing as it will offer greater freedom of movement and comfort.

Sailing in all weather conditions is part of the thrill but can also be unpredictable. To stay dry and protected from harsh elements such as wind and rain, invest in high-quality foul-weather gear. This includes waterproof jackets, trousers, gloves, and boots – items that are designed to keep you warm and dry even when faced with challenging weather conditions .

A properly fitted helmet is often overlooked by sailors but can make all the difference in terms of safety. During high-speed maneuvers or unexpected jibes, there’s always a risk of hitting your head on rigging or other equipment onboard. A lightweight helmet designed specifically for sailing will provide crucial protection without hindering movement or comfort.

In addition to protective gear, certain precautionary measures should be taken before setting sail on your 505 boat. Regular maintenance checks are crucial to ensure that your vessel is in optimal condition – paying attention to essentials such as rigging tension, hull integrity, and keel bolts can prevent potential accidents while out on the water.

Before heading out, it’s also vital to evaluate weather conditions and plan your route accordingly. Being aware of potential hazards and adjusting your course or timing can prevent unnecessary risks. Don’t forget to inform someone onshore about your sailing plans, including estimated return time, to assure that help is readily available should an emergency arise.

Lastly, staying knowledgeable about safety procedures and techniques is key for any sailor. Enroll in a sailing safety course specific to 505 boats to gain insights into best practices and emergency protocols. These courses will equip you with the necessary knowledge and skills to handle unforeseen situations that may occur while out at sea.

To sum it all up, when it comes to 505 sailing, “safety first” is the golden rule. Equipping yourself with essential gear such as a PFD, foul-weather gear , and a helmet is paramount for your protection during high-speed maneuvers or changing weather conditions. Additionally, diligent maintenance checks and route planning are crucial precautions before setting sail . Lastly, never underestimate the value of learning and refreshing your knowledge through dedicated safety courses.

Remember, the real enjoyment of 505 sailing lies not only in its exhilaration but also in knowing that you have taken all necessary steps to keep yourself safe onboard. Stay prepared, stay informed, and embrace the thrill of this incredible sport with peace of mind!

Fleet 4 505, report on year one

This spring the Nepean Sailing Club (NSC) supported the Ottawa 505 Fleet in purchasing a 505 to promote fleet building and encourage participation in the class. The boat maintenance, sailors’ selection and mentorship were managed by a team of three 505 sailors: Paul Place, Shona Moss and Marie Gendron. Following are the program highlights:

  • The boat was sailed by over 15 individuals (several repeat users); 
  • Used at four regattas and two training clinic’s.
  • Sailed at 7 Wednesday evening dinghy racing nights at NSC;
  • Several practice outings by users of the fleet boat throughout the summer.
  • One of the objectives at the start of the season was to see the boat sailed at both NSC regattas. We had two different teams sail both the Nepean One Design and Nepean FANFARE Regatta. Notably, the team that sailed at FANFARE had several strong finishes. The boat was also used at out-of-town events during the fleet’s annual clinic at the Kingston Yacht Club, the 505 Canadians at CORK and at the 505 East Coast Championships in Sakonnet, Rhode Island. One of the highlights was that the fleet boat provided an opportunity for two former NSC sailing school instructors to experience the 505 fleet throughout the summer. They decided to participate in the 505 East Coast Championships and were able to borrow the boat to sail at this event. 
  • The Fleet boat was used at the annual 505 Espoir Camp held in late September. The Espoir Camp is an annual clinic organized by the fleet to provide an opportunity for new and young sailors to try the class. Participants are usually sailors from the local 420 and ILCA youth race teams. Boats are lent to the participants for the day by members of the fleet. This year the camp had 13 participants and 6 boats.
  • Structured and unstructured mentorship was provided to those using the boat at regattas by 505 fleet members. This was often done by pairing the new sailor with a more experienced crew or driver with strong experience in the 505 along with on land debriefing after races. 
  • The team feels as though it has provided an opportunity that did not previously exist for experienced sailors to test the boat. It has generated more interest in the class mainly from youth sailors in the Britannia Yacht Club and NSC dinghy programs along with other dinghy sailors at NSC. The fleet remains the most active and competitive dinghy fleet at NSC. We had one new boat join the fleet this year and another one is set to join next year (currently 14 boats in the NSC dinghy yard). The fleet boat contributes to this activity and growth in the fleet. 
  • The 505 Fleet Boat team is looking forward to continuing the program next year and building on the success from this year while taking stock of lessons learned.

The regatta spanned three days, but the first day proved challenging due to strong winds ranging from 25 to 30 knots and sizable waves. While some teams ventured out, it was collectively decided that the conditions were too extreme for racing.

The second day brought a shift in the weather, with light southeast winds and lingering rolling waves and chop. Ted Heubner and Aiden Naughten from the USA got off to a strong start, securing two first-place finishes. Remarkably, this was Aiden’s first 505 racing experience. The Toronto/Ottawa duo of Robert Bartlewski and Adam Gesing were solidly in second with two third-place finishes. Craig Thompson and Adam Wolnikowski from the USA rounded out the top three with scores of 2 and 5, demonstrating excellent speed on the water. Jeff Boyd and Martin Ten Hove from Kingston were in fourth with a 7th and a second place, despite the difficult sailing conditions.

Consistency became paramount, a challenging feat given the shifting winds and pressure variations. Sunday ushered in a refreshing northeast breeze, characterized by shifts but initially full trapezing. Four races were completed, with the first three conducted under wire-run conditions and the last featuring slightly less wind. Thompson and Wolnikowski found their rhythm on Sunday, tallying scores of (18), 1, 4, 3, which, when added to their 2nd and 5th from Saturday, led to a net score of 15, catapulting them into the lead (with a throw-out provision).

Duane Delfosse and Mike Hull from the USA scored (14), 5, 6, 2 on Sunday, which, combined with their 5th and 6th-place finishes from Saturday, resulted in a score of 24, gaining them second place. Henry Amthor and Chris Pfrang, also from the USA, showcased consistent improvement over the two days, earning (14), 9, 12, 4, 2, 4, and ultimately claiming third place with 31 points. Impressively, five different teams notched victories in individual races.

Among the Canadian teams, Robert Bartlewski and Andrew Gesing placed highest, finishing in 7th place, followed by Jeff Boyd and Martin ten Hove in 8th. A special mention goes to Ali Meller and Russell Miller, who mounted a strong comeback on Sunday with 3rd and 1st-place finishes in races 4 and 5 but regrettably had to return to shore before the last race of the day following a collision with another boat (for which they were not at fault).

Kudos to Craig Thompson and Adam Wolnikowski from the USA for their outstanding performance in this championship, which served as an excellent warm-up for the upcoming Worlds. We extend our immense gratitude to John Ingalls for his meticulous organization of the regatta, PRO Cushing Anderson, and the numerous volunteers, especially the generous housing hosts. John’s efforts were instrumental in accommodating over 20 people, including most of the Canadian sailors, in homes in Little Compton, a remarkable achievement.

Kingston 2023 Canadian 5O5 Championships

Regatta report courtesy of Peter Scannell, emeritus chair of sailing instruction studies at 505 University.   

The 2023 Canadian Championships was held on July 22-23 rd   as part of the CORK skiff week in Kingston, Ontario.  Fourteen Canadian entries were joined by five visiting US boats, making a fine turnout of 19 boats.   Forecast was uncertain, with light winds expected for both days. 

Saturday started out with about 10kts from the NW with large gusts and lulls across the course.  For race 1, logic suggested going left to avoid the shadow of the land, and for a while it worked, with Tom Kivney and Gordon Russell looking like early leaders.  However it was the rabbit, Jeff Boyd and Martin ten Hove who continued right and found a large right hander with pressure to lead into the first mark.   

Downwind, there was a mix of wiring and sitting.  Peter Scannell and John Dunlea elected to gybe-set and were rewarded with good pressure to allow them to wire and gain about 8 places.  The remainder of the race was all about finding the pressure, with lots of opportunities for big gains.  Jeff and Martin held on for the win, with Tom/Gordon second and Peter/John crossing the line in third.  

In Race 2, Scannell/Dunlea took control at the midway point and led the fleet home ahead of John Ingalls and stand-in helm Alex Bowdler, with Dave Kirkpatrick and Sol Marini in third and Jeff and Martin fourth.  At this point, Scannell/Dunlea realized it would have paid to have read the sailing instructions, when they realized they had failed to finish correctly for both of the opening races.  Going back around, they managed to salvage a 7 th  by refinishing race 2.          

Bowdler/Ingalls were starting to gel and won race 3 from Kirkpatrick/Marini with Scannell/Dunlea in third. 

Race 4 went to 2021 Canadian Champ Robert Bartlewski sailing with Andrew Gesing who succeeded in sniffing out shifts and pressure to hold on to win over Scannell/Dunlea with Shona Weldon and Michael Wonnacott in third. 

 Day 2’s forecast promised more wind with a typical SW Kingston breeze that would build if the sun stayed out.  

Race 5 was light, with Scannell/Dunlea chasing Ingalls/Bowdler around the course before stealing the lead on the last run to finish ahead by a boatlength.  Bartlewski/Gesing were third with Kirkpatrick/Marini in fourth.  

Race 6 was in similar conditions with Scannell/Dunlea leading from the first mark to the finish.  Behind them, 5 or 6 boats converged at the finish to all cross the line within seconds of each other.  Ali Meller and Steve Lovshin grabbed the second spot with Duane Delfosse and Mike Hull in third. 

The legendary Kingston thermal finally started to build by Race 7 and Kirkpatrick/Marini took the win in great wire-running conditions ahead of Ingalls/Bowdler with Kivney/Russell in third. 

Race 8 was a carbon-copy for 1 st  and 2 nd  places, with Delfosse/Hull grabbing third place. 

Overall, that left John Ingalls and newcomer Alex Bowdler in first place, one point ahead of Dave Kirkpatrick and Sol Marini.  Peter Scannell and John Dunlea salvaged third place overall by sailing the last race without a tiller extension, having used up their discard with Saturdays finish-line antics. 

Best placed Canadian boat was Jeff Boyd and Martin ten Hove in 4 th  place.

Special thanks to the local Kingston fleet who housed many of the visitors. 

CAN notes: Second Canadian team and 5 th overall were Robert Bartleski/Andrew Gesing (only 1pt behind Boyd/ten Hove) and 3 rd Canadian and 8 th overall Shona Moss Lovshin/David Mincoff who were sailing Marek’s boat.  Special mention to Ali Meller/Steve Lovshin who lost their rake/tension system on Saturday. They spent the day onshore rebuilding the system. They got back on the water Sunday to finish 5 th , 2 nd , 8 th , then RET due to another boat failure, this time to their spi pole system.  

Thank you to all CORK volunteers for hosting the event. (–Marie Gendron)

Ten Technique Tips for New 505 Crews by Jesse Falsone

Home » Library » Improve Your 505 Sailing » Ten Technique Tips for New 505 Crews

Having crewed a 505 continuously for 15 years and 9 world championships gives one a very good perspective on proper technique. Being a student in the evolving art of crewing, and now moving part-time to the back of the bus, I am in a unique position to see how a new 505 crew approaches the craft, and moreover, to give these people useful instruction. As Mike Martin has shown, a helmsman knowledgeable about crewing technique can quickly develop a new crew, and make experienced crews better.

A major goal in the 505 class is not only to attract the best sailors to 505 crewing, but to keep them motivated, and ultimately, to share in the dream of winning at the highest levels in our class. The best way to keep someone motivated is through continual improvement, and it is with that premise that I offer the following tips and also an accounting of the most common technique mistakes made by new 505 crews.

As a card-carrying member of the Crew’s Union, I can’t go back on the #1 rule –“It’s always the skipper’s fault”. In fact, this article could just as well be a treatise on the most common technique mistakes made by new 505 drivers, and highlight my antics holding the tiller in several regattas. However, this would be too easy, because we all know it’s harder to crew the 505, and this subject matter is best saved for a separate article. But, be certain that one will follow! I’m still waiting for an experienced helm to write a technique article, but in all the time I’ve sailed the 505, not a single driver has ever stepped up to the plate to do so despite my prodding. Will I become so lazy as a driver?

I have made nearly every conceivable mistake in the front of the 505, and some that seem inconceivable, so I will restrict this piece to basic techniques, which are the most important for rapid improvement. I have omitted any discussion on jibing with a single pole for now because it seems that the double pole phenomenon has taken hold and has made OBE many technique-related issues. Jibing a 505 from the front now seems too easy in breeze. I will have to wait until I actually have experience using the double pole before I make the necessary mistakes to comment accurately!

I would also recommend reading the many other articles I and others have written on crewing technique which are available in previous issues of Tank Talk online. Also, Drew Buttner’s recent interview with Mike Martin in Sailing World (http://www.sailingworld.com/0911martin) has some special insights into his approach and how experience in both positions is extremely valuable.

Crews should remember that their largest asset and driving force is the desire to get better, and to approach learning with an open mind. While there may be more than one technique that works in a maneuver, there will be only one that works best for a team. Even if you’ve been crewing for a long time, and have become relatively set in your ways, it may be that another technique, once perfected, will work better. Be open to change.

Wire-to-Wire Tacks in Medium and Heavy Air

Always uncleat with the back hand and unhook from the wire with the front hand before the boat is turned into the tack. This assures that a cleated jib or hooked crew won’t force a capsize during the tack.

You know you’ve done it right when you don’t have a mad scramble across the boat because your timing was destroyed by a cleated jib or unhooked ring.

Get across the boat quickly! Don’t wait for the driver to turn. Make the driver “tack around the crew”. Once the driver indicates they are about to tack, the crew should go. A good driver will regulate the speed of the turn to the speed of the crew.

You know you’ve done it right if the boat remains relatively flat through the tack, and the crew gets to the new side ahead of the driver.

Toss the uncleated jib sheet forward before crossing the boat so your feet don’t get tangled during the tack. Also, resist the temptation to hold the jib sheet too long causing the jib to backwind or the old sheet to wrap on fittings. This is especially important in heavy air when you want to get the bow through the wind quickly with a minimum of rudder movement and boat heel.

You know you’ve done it right when the rate of turn is measured and consistent and not extreme and abrupt.

Rather than standing on the side of the hull during a wire-to-wire tack as you might in a skiff, un-weight your body by swinging in on the wire. I like to lift my back leg and point it to the opposite side as I swing in. This technique allows the crew to move more smoothly into the boat by promoting transverse movement rather than vertical. It also allows the crew to place his back foot completely over the trunk and onto the new weather side, which is crucial for a smooth tack. Lead with the back foot through a tack rather than your head. No bunny hopping over the trunk! It’s slow and clumsy.

You know you’ve done it right when your tacks feel smooth with less effort.

Grab the new jib sheet at the cleat with the goal of getting it trimmed and cleated as quickly as possible. The trimming motion is a combination of spinning and pulling with your new back hand as you come to the weather side and sit. Mechanically, it may help to pull with your hand skimming along the top of the new weather tank rather than up in space. This allows for the trimming and cleating in one motion with no need to take extra time to get the sheet in the cleat. It also assures that the sheet won’t blow out of the cleat when loaded.

Get out on the wire before the boat heels up. It took me a few years to convert to the “Hook and Go” tack, but I can tell you that done properly, it’s better in every respect. I believe the trick is to grab the trapeze ring with your new front hand and place it in the hook. The best crews can do this without looking, and they are then free to throw their torso over the side and get their feet on the rail. Watch Peter Alarie do it because he’s the best in the business.

You know you’ve done it right when you pop out on the wire with ease just as the driver is ready to trim the main. You have expended far less energy during the tack, the boat immediately accelerates, and you have that “I’m a rock star” feeling as you roll over some chump with poor technique!

Trapeze Technique

Don’t allow yourself to get pushed around by waves, boat motions, and inertial forces during a hard turn. Recognize that there’s extraordinary strength in your legs to counter these things, and that being alert at all times will allow you to anticipate them. Be careful of being too low on the wire in heavy seas, and in extreme conditions, you may need to stabilize your body by spreading your legs slightly and holding the jib sheet more tightly to create a “tripod” stability effect.

You know you’ve done it right when you remain aft of the shrouds and forward of the driver!

Optimize your leverage for the conditions. The goal is to ring as much driving force from the rig as possible at all times. When the breeze is on and the crew is in a relatively static position on the wire, focus on getting your weight as far out as possible by going low on the wire, straightening your legs and torso, placing one or both hands behind your head, and pointing your toes. Don’t over-adjust your height. Find the sweet spot for the conditions, and if you’re low on the wire, consider bending at the torso slightly to reduce leverage if necessary rather than making a height adjustment. When sailing on a tight spinnaker reach with the boat heeled and riding on the leeward quarter, get very low on the wire to counter the heel.

You know that you’ve done it right when you are focused more on trim and tactics and less on ring height. Also, you are able to sense when more leverage is required, especially when the driver needs to trim the main harder.

Trimming Technique

Be sensitive to changes in wind speed by adjusting your jib sheet tension accordingly. Changes in wind speed can dramatically alter the shape of the jib, especially at the leech. Making timely and accurate changes are a great way to improve performance. Try using the transverse distance from the leech at the telltale to the shroud as a reference. Keeping the leech just outside the shroud at all times may be a good starting point in most conditions. Learn to calibrate this distance depending on the conditions, using your jib sheet numbers as a guide for repeating fast settings quickly.

You know you’ve done it right when the driver doesn’t need to say “trim” or “ease” the jib.

In very windy conditions, the crew needs to be ready to blow the jib instantly and momentarily (very quick in-out) to keep boat on it’s feet without losing speed through the waves. Personally, I do not like risers or angles on jib cleats in a Waterat or Rondar (jib cleat heights vary with thwart height for other boats). The risers and angles make it more difficult to get the jib blown in heavy air. In all likelihood, the crew should have a fairly tight grip on the jib sheet in heavy air anyway, and this should make it easier to effect a quick adjustment.

You know you’ve done it right after a big gust when the driver thanks you and recognizes that the team would’ve been swimming had you not been ready for the gust.

Rudder stall downwind is most commonly caused by an over-trimmed kite. Mike Martin says “Next Time you are driving on a tight reach in breeze, have the crew slightly overtrim the kite. You wont believe how much the helm loads up!” The crew has to retain focus on the kite when it’s critical, and let the driver worry about downwind tactics. If the rudder begins to stall, the only way to stop it is to immediately flog the kite. Easing it partially or too slowly will not save you!

Note: Experienced crews can sense when rudder is beginning to stall, and knows the motion the boat takes that can cause a rapid stall. This motion is caused by the leeward bow hitting the back of a wave suddenly, causing a pitch/heel coupling that forces the bow up. The driver instinctively pulls the rudder hard causing the stall.

You know you’ve done it right when boats around you are wiping out and you’re flying past them.

You may have heard that 505’s are some of the most well-made dinghy’s around. Many 505’s can stay competitive for an indefinite period of time when well cared for. Some older 505’s were not built as well, and may not be worth spending time and money on to get back on the race course. This page is organized in a way to help you determine which boat is right for your own 505 sailing goals. Visit the list of builders for more information on all the various 505 builders throughout the years. Also, hull numbers are sequential, and are issued upon initial measurement after the boat is built. The minimum weight of a 505 (weighed with all equipment required for racing except sails) is 127.4kg or 280.9 pounds. Many boats have lead corrector weights (50% located at front of CB trunk, 50% located at rear of CB trunk) to bring the boat up to this minimum weight.

The used boat ads on this page are organized based on the following classification scheme:

The Surtees Service Award was dedicated at last year’s NA’s to commemorate outstanding service to the American Section. The inaugural award was presented to Ali Meller.

It is a pleasure to introduce the 2003 winner of the Surtees Service Award – Jesse Falsone.

As all of you know, Jesse is the epitome of the “go-to guy” for our Class. When a valuable role within the American Section needs to be filled, Jesse has never been afraid to put his money where his mouth is and step up to the task.

In the eight years that he has been in the Class, Jesse has served as both Class Secretary/Treasurer, and President of the American Section.

Upon “retiring” as Class President, Jesse took on the role of Tank Talk Associate Editor, and over the past few years, no one has contributed more material to Tank Talk than Jesse.

Jesse is an incredibly focused competitor who has always found time to pass his knowledge along. After working for years to become one of the top 5o5 crews in North America, Jesse published a compendium on “High Performance Dingy Crewing,” utilizing both his knowledge and that of other top NA 5o5 crews. This pamphlet runs 33 pages, and is literally a textbook of how to climb the learning curve for a 5o5 crew. Any skippers out there up to the challenge?

Jesse has set the bar for 5o5 class members, dedicating a superhuman amount of time & effort into making the American Section the solid organization that it is today.

Although he is taking a well-deserved break from the 5o5 and cannot be here today, let’s have a big round of applause for Jesse.

Ted Ferrarone

I’m very proud to have commissioned this new service award bearing the name of one of our most distinguished members: Dennis Surtees’. Dennis is a legend in this class, both for his outstanding performance and for his superlative service. I’m equally proud to have Ali Meller as the first recipient. Ali has served in so many capacities for this class, most of which many of you don’t know about or may have forgotten. Ali has been fleet captain in the US for two different fleets (maybe more in Canada?). In one of these he was largely responsible for the creation of this fleet at a new club. He served as VP of the American Section, Editor of Tank Talk, VP of international (an office created for him), and is now completing his term as President of international. As webmaster, Ali took the 505 web page and made it the most informative class page on the Internet. US Sailing used our web page as an example of what a great class web page should look like. Ali was also instrumental in introducing countless people to the 505 through personal communications and through sailing time.

Ali’s leadership came along at a crucial time for the 505 class. In the early 90’s we were a class teetering precariously on the seesaw of success and failure. Our numbers in the US had steadily declined, and the class lacked direction. Ali was the catalyst for our resurgence, and a large reason why we all enjoy fine competition today.

Simply put, nobody in the world has put more into the 505 class in the past decade than Ali Meller.

Ali, on behalf of the 505 American Section, it’s my honor to present you with the Dennis Surtees Service Award for 2002.

“I nominate Bill McKinney and Stine Cacavas for the Cahn award. Bill has been with the San Diego for over ten years, and is the guy who always spends regattas in good spirit, with lots of humor, humbleness and grace. And style. After coming in from the race course early one day in Santa Cruz, while sitting in his chair, he greeted every sailor at the ramp with a cold Corona with lime. Yes, his regatta kit includes chairs, a cooler on wheels, and a cutting board. Stine has been sailing with Bill for a few years now, and while she shares Bill’s positive attitude, she also brings a new level of competition to the team. They competed in the 2010 worlds in Denmark sailing Fever Pitch, Dave Cahn’s own Lindsay. For the 2012 worlds in France they upped their game, buying a newer Waterat. I take this as a good sign that they will continue to favor us with their company for many years to come.”

Aaron Ross, USA 7156

The Dave Chan award goes out to the individual or team that expresses sportsmanship in the unique way of 505 sailing because they love 505 sailing. The award is not necessarily for the guy that wins all the races, but the guy you would most like to have a beer with at the end of the day.

These guys fit that description perfectly. They both came into the 505 picture from illustrious lead mining careers. After the first day of proper breeze in a 505 they were hooked. Since then they have enjoyed attending many of the events in northern and southern California. At the end of the day they are always thrilled with whatever they experienced and learned on the water. They are always willing to lend a helping hand despite the fact that they are usually involved in some major repair project themselves. It is always a pleasure having these guys around both on and off the water and we would all have more fun if we adopted their attitude. That is why this year the Dave Cahn award should go to Brad Wheeler and Bill Mais.

As most of you know, the Dave Cahn trophy was created in 1998, in memoriam of Dave Cahn, and his special brand of sportsmanship. Past winners have included Eric Willis/Wendy Herzburg, Barney Harris, Dan Merino/Bill Jenkins, Henry Amthor, and in 2002, Stuart Park.

Please give a big round of applause for the winner of the 2003 Dave Cahn Trophy: Paul Von Grey.

Paul’s nomination for this award was so excellent, that we will just read it to you:

“I would like to Nominate Paul Von Grey of the Pacific Northwest Fleet for the Dave Cahn Trophy. Paul has virtually single-handedly (no pun intended) been the motivation for the resurgence of the 505 fleet in Washington. He has helped push attendance at regattas from an average of three boats to a recent high of 16. He regularly rounds up sailors following races to debrief on successful and unsuccessful strategies and rigging tips. He serves as the unofficial parts warehouse for most of the sailors in Washington and probably has contributed parts, time or rigging advice to a majority of boats in Washington, Oregon, and British Columbia. He helped obtain a container of highly competitive boats that have raised the quality of racing dramatically. Whether you are a current 505 owner who needs to locate crew or a prospective 505 competitor who wants to go for a test ride, Paul is the guy who helps make the connection. He successfully poaches new 505 sailors from other fleets at regattas and every new sailor in the local fleet has probably been pointed to Paul as the guy to talk to about 505’s.

The Pacific Northwest fleet is a knowledgeable, friendly and helpful group of people and the description above could apply to every person in the fleet, however, no person embodies all of those qualities as completely as Paul.”

Let’s give another round of applause for Paul Von Grey!!

Nominated by Dave Stetson

Jesse, I wish to nominate Graham Alexander for an honorary life-membership in the class.

Graham first became a 5-oher around about 1967 and he has been one ever since. I know only a few on this side of the pond with that kind of longevity in the class. He has owned at least six boats, beginning with a 2XXX series boat; he currently owns two, a 45xx Rondar rigged to race with other classics, and Parker 7685. Not only has Graham been loyal to the class with his presence, he has been one of the class’ most ardent recruiters here in the Midwest. Within two weeks of the day I moved to Columbus in 1985, he was in my kitchen pushing me into the fray, getting me onto the boat, and helping me to find a crew slot. He has introduced dozens of people to the boat during the 17 years I have been around to watch.

In addition to recruiting, Graham has been the organizer of the class in Region 3 for as long as anyone can remember. Ki Kaiser and Graham have worked together ensuring a variety of regattas and spreading the word. He was the formal Midwest coordinator for most of the years since 1970.

Graham has been extremely generous with his time helping people to buy boats, helping them to rig them well, and helping to repair them when they broke. He has loaned his garage, his tools and equipment, his hands, and his expertise for fiberglass work, vacuum bagging, and rigging. Each winter, he has taught Sunday-evening courses on racing rules and tactics, crewing and helming skills to groups of local sailors, including newbees and hardened veterans.

Graham has been one of the true fixtures in the class and he has been one of its best public-relations specialists. Through his energy and love of the boat and the class, he has kept 505s in the Midwest and has kept Fleet 17 alive at Hoover Yacht Club. He may not be the most jolly of 505 sailors because he takes his sailing very seriously. It is integral to his core as a person and his love for the class is infectious. Because of his dedication and generosity, I believe he is as close to a life member as one could come.

Nominated by: Mike Martin and Ryan Cox Presented by: Dennis Surtees

Most of the time when we think about an award for service to a class we think about class officers or people that have volunteered their time in a very broad manner. Howard has served this way in the past by being an international class president but that is not why he deserves this award. Everyday Howard provides service to the class on a much more personal level.

The services that he provides range from straightening a mast, to loaning out his coach boat out free of charge, or letting people use his tools or even his entire garage. If you don’t know how to fix something on your 505, you need a tool or a part, who is the first person that you ask?

His services are organizational as well. Howie is always thinking of ways to better himself and always passes what he learns on to the fleet, even if it is one boat at a time. The Long Beach fleet would simply not exist without Howie. Every year howie takes the lead in organizing our weekly practices. A few years ago Team Tuesday was 1 or 2 boats, this year we often see 7 or 8.

Howie has also provided a huge service to the development of the equipment that we use today. 25 years ago he built molds and long lasting Honeycomb Kevlar boats that are still competitive today. Howies funding of the blade development program resulted in production centerboards that cost every one else much less than the developmental price that he paid.

There is no one more valuable to our fleet than Howard. So whether or not he wins this award, next time you see him, just say “Thanks Howie”!

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
