Summary Analysis of the Design Ratios for the Tayana 37

1. A Sail Area/Displacement Ratio of 17.4 suggests that the Tayana 37 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.

2. A Ballast/Displacement Ratio of 35.6 means that unless the bulk of the ballast is concentrated in a bulb at the foot of her keel, the Tayana 37 will have a tendency to heel excessively in a gust, and she'll need to be reefed early to keep her sailing upright in a moderate breeze. 

3. A Displacement/Length Ratio of 337, tells us the Tayana 37 is clearly a heavy displacement cruising boat. You can load her down with all your cruising gear and equipment and it will hardly affect her waterline. Not an ideal choice for coastal sailing, but she'll come into her own on an offshore passage in testing conditions.

4. Ted Brewer's Comfort Ratio of 41.1 suggests that crew comfort of a Tayana 37 in a seaway is similar to what you would associate with the motion of a heavy bluewater cruising boat. Pitching and rolling will be well damped - your cup of coffee on the salon table stands a reasonable chance of staying there in most conditions.

5. The Capsize Screening Formula (CSF) of 1.6 tells us that a Tayana 37 would be a considerably safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0. 

The Tayana 37 below decks...

The interior could be customized to suit the owner's preferences, but a typical configuration has sleeping accommodation for six people, with a V-berth in the forecabin, a U-shaped settee with a drop-down dinette table and a straight settee opposite, and a quarter berth on the starboard side extending under the cockpit. The head was located on the port side between the forecabin and the main cabin. The galley was U-shaped and located at the foot of the companionway steps on the port side. The navigation station was located opposite the galley, on the starboard side.

Cruisers' Questions about this Sailboat...

How many versions of the Tayana 37 were produced and how do they differ?

There were two main versions of the Tayana 37: the cutter-rigged sloop and the ketch rig. The cutter rig was more popular and had a sail area of 846ft 2 (78.6m 2 ), while the ketch rig had a sail area of 1,000ft 2 (92.9m 2 ). There was also a pilothouse version for those that prefer more protection from the elements.

How does the Tayana 37 perform under sail?

The Tayana 37 is known for its excellent performance under sail, especially in heavy weather and long passages. It is stable, balanced, and responsive, with good windward ability and speed potential. In light winds however, its heavy displacement and large wetted are work against it.

How much does a Tayana 37 cost?

The price of a new Tayana 37 depends on the options and customizations chosen by the owner, but it is estimated to be around $250,000 USD as of 2020. The price of a used Tayana 37 varies depending on the year, condition, and equipment of the boat, but it can range from $40,000 to $100,000 USD or more.

What is the history of Ta Yang Yacht Building?

Ta Yang Yacht Building is a Taiwanese company that specializes in building semi-custom sailing vessels ranging in size from 32 to 72 feet. The company was founded in 1973 in Kaohsiung, Taiwan, by C.T. Chen, who also co-founded Ta Chiao Yacht Building. The company's name means "big ocean" in Mandarin, and its brand name Tayana means "belongs to big ocean" .

The company's first model was the Sea Wolf 41, also known as the Yankee Clipper, followed by the Tanton cat ketch. In 1979 the company introduced the Tayana 37.

The company has since produced many other models, such as the Tayana Vancouver 42, the Tayana 48, the Tayana 55, and the Tayana 72. The company also offers deck saloon and pilothouse versions of some of its yachts. The company's yachts are known for their quality, performance, and seaworthiness. As of 2012, the company had built over 1,400 yachts.

Unfortunately, Ta Yang Yacht Building has been closed of business since September 2020.

Who is Robert Perry and what other boats has he designed?

Robert Perry is a U.S. yacht designer based in Seattle, Washington. He is one of the most influential and prolific designers of modern cruising yachts, with over 200 designs to his credit.

He started his career in 1970, working for Jay Benford and then Dick Carter. His first design was the CT 54, a clipper-bowed ketch built by Ta Yang Yacht Building in Taiwan. His breakthrough design was the Valiant 40, a performance cruiser that introduced the concept of a fin keel and skeg hung rudder on a double-ended hull.

Perry has designed boats for many well-known brands, such as Tayana, Cheoy Lee, Valiant, Baba, Ta Shing, Islander, Passport and Saga. He has also designed many custom yachts for individual clients, ranging from 24 to 97 feet in length. Some of his most famous and iconic designs include the Tayana 37, the Tayana 48, the Saga 43, the Nordic 44, the Passport 40, and the Flying Dutchman 12 meter (FD-12).

Perry has also taught yacht design at Evergreen State College and written several books and articles on yacht design and sailing. He is active on social media and runs his own website where he showcases his designs and shares his insights on yacht design. He is still designing new boats and enjoys sailing on his own boat, a Perry-designed Saga 43 named 'Flashgirl' .

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)

From BlueWaterBoats.org :

The Tayana 37 is perhaps the most successful semi-custom cruising yacht to be built. It was designed by Bob Perry and introduced in 1975 as a response to the Westsail 32 which were selling in enormous numbers. Today looking back, with the boat still in production with a boat count of 588, most still sailing, and an active and owners community, it’s very apparent that Perry has succeeded.

One could say the yacht was designed to ignite imaginations of tropical sunsets in exotic locations; think oodles of teak and a beautiful custom interior, wrapped into traditional double-ender hull with a full keel. Beneath the alluring romance, you’ll find a boat that is solidly built, and indeed many Tayana 37s can be found on the blue water cruising circuit around the world.

When in June of 1973 Time Magazine featured a four page spread on the “cruising life” with a photo of the Westsail 32 it was clear that this diminutive boat had caught the imagination of a generation. They sold like hotcakes and the cruising life came out of the fringes and into the mainstream. Meanwhile, fresh from the success of his groundbreaking Valiant 40 and having more recently designed the CT 54 Perry was approached by Bob Berg, former owner of Flying Dutchman Yachts in Seattle, to design a boat to capitalize on the success of the Westsail. It is said that the success of the Westsail was not that it was the right boat at the right time, it was also the right style; it was exactly what Americans thought a cruising boat should look like. This may explain the Tayana’s copious amounts of teak, her traditional full keel, and double ender style.

The boatyard that was originally selected to build the boat was Ta Chaio Brothers of Taiwan, builders of CT yachts. Interestingly, they declined thinking the boat would not be a commercial success. Thus the contract to build the boat was passed to Ta Yang, another high quality Taiwanese boatbuilding concern.

The boat, which was first known as the “CT 37”, was introduced in 1975 and offered as a semi-custom boat, with all manner of internal options and layouts. The rig was offered with options of cutter or ketch, however cutters were the fashion of the day and only 20 boats were built as ketches. In 1979 the CT 37 name was discontinued, instead boat inherited an offshoot of the Ta Yang name, changing to the Tayana 37.

The Tayana 37 continues to be in production today in very low numbers, they have declined in sales as buyer tastes have favored boats with more expansive interiors, stern entry, and avoidance of higher maintenance teak on the exterior. However the Tayana 37 remains popular in the used boat market, at the time of writing the Tayana Owners Association reports the latest hull number is 588 or 589.

Boat Configuration

The Tayana 37 is a classic full keel double-ender which when we look back today marks the start of modern design philosophy for full keel boats. Perry took a very traditional Atkins 1930s inspired design and worked his “boatspeed” magic firstly by cutting away forefoot of the keel, a common technique to reduce wetted area with gains in maneuverability. He then connected the keel to the bilge of the hull as a distinctly separate surface without the traditional wine-glass blend, which tends to help with close-windedness and form stability. Other deviations to the Archer theme included his own flavor of a canoe stern which had worked well in his radical at the time Valiant 40 design as well as opting for a modern inboard rudder over the traditional aft hanging rudder that Archer used.

Most boats are configured with cutter rigs carrying a lot of sail area with the help of a bowsprit. Those with a keen eye may notice the mast position quite far aft from the usual position on most yachts and this has been the cause for some windward helm issues which in the early days was corrected by raking the mast forward. It’s rare to find a Tayana 37 sporting the optional ketch rig which Perry notes is a pity as he thought the ketch examples were particularly fast and well balanced.

On deck, you will find lots of teak, some owners have removed the teak in order to reduce maintenance. The side decks are wide. There are two deck versions, the first being designed by Perry, which was later revised by Ta Yang which according to Perry is far nicer, more aesthetic, with a better cockpit. Most boats have the original Perry designed cockpit. Both versions sport small volume cockpits well suited to mitigating the risk of the cockpit flooding from large following seas. The cockpit has been described as safe secure with high coamings. Visibility forward from the helm is usually impeded by on most boats by butterfly hatches, boom gallows, and mid boom sheeting.

Going below deck you will find a high quality interior reflecting some of the best boatbuilding craftsmanship to come out of Taiwan. The interiors are all semi-custom and it’s unlikely to find two boats identical. While some interiors were well suited to blue water sailing others were not so functional. Blue Water Sailing Magazine writes, “We have seen some interiors that were simply inappropriate for a seagoing boat. Truth is many people who ordered new Tayanas did not have the knowledge to make the choices that were required of them, and either made bad choices or tried to fit too much into a hull already restricted by its design”.

Of note is the location of the fuel tank. In the original design, Perry located the 90 gallon tank below the saloon settee, but Ta Yang relocated them forward to in the fore peak, with the idea of creating more stowage space in the saloon. A full tank weighing 700 pounds so far forward has resulted in trim problems and hobby-horsing. It’s reported a some owners have relocated their fuel tank back to the original spot that Perry intended.

Construction

The Tayana 37 hull is built from solid GRP, generous amounts of glass is used, the hull is 3/8″ thick at its sheer. Perry has been quoted as saying there has never been any consistent structural problems with the boat. The deck is balsa cored to save on topside weight. The ballast is cast iron and internal to the keel cavity and glassed over. The hull-deck join is built into a strong hollow box section, which forms a high standing bulwark.

Sailing Charateristics

One would not expect the Tayana 37 to progress with much vigor from a fleeting glance, however the Bob Perry makeover of the traditional Atkins configuration gives the boat a new lease of life. The boat performs faster than similar boats of this period, especially in a fresh breeze.

The Tayana is relatively tender initially. The first reef is usually thrown in at about 18 knots, in 20-25 knots it’s usually a staysail and the single reefed main. The boat tracks well to windward, but its forte is off the wind, particularly in a broad reach; ideal for the trades.

The cockpit is dry, Tayana 37 owner Rolland Hartstrom writes of a passage between from San Francisco to San Pedro in Mar 2009, “I surfed down 20 footers in this boat doing 14 knots, and they were breaking about 3 feet of white water on top; never took a drop of water in the cockpit”.

Probably the most common bugbear of the Tayana 37 under sail is its often cited weather helm in boats configured with cutter rigs. Many of these problems have been corrected through the years by their owners, some by raking the mast forward. Harvey Karten from the Tayana Owners Association notes, “When properly rigged with a good adjustable traveler and well made sails, rather than their original factory configuration, the much reported weather helm is no longer a problem.”

Buyers Notes

There is an enthusiastic and active owners association with a wealth of information and tips to share, well worth contacting prior to purchase. Particular areas for inspection are listed below:

• Teak decks have proved high maintenance, many boats have had their teak removed which is considered an advantage.
• Look for delamination around through deck fitting, the balsa cored deck is susceptible to abuse.
• Water tanks are made of black iron and are prone to rusting over time, check for leaks.
• Some boats have fuel tanks relocated back into their proper amidships intended location, its a recommended modification.
• Glaring inconsistencies between boats have been noted
• Boats before 1981 should have their wiring and standing rigging inspected closely.
• Early boats had spreaders made from spruce which can be susceptible to dry rot, alloy spreaders on later boats are an advantage.
• There have been reports of leaking from the scuppers and hawsepipes, this problem has been solved in later models by glassing the bulwark from the insides.

As of 2010 asking prices range from $55k-$115k USD.
