Calculations

Hull Speed
7.6 kn
Classic: 7.39 kn

Hull Speed

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.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

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

7.55 knots
Classic formula: 7.39 knots
Sail Area/Displacement
15.1
<16: under powered

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.

Formula

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.
15.11
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
42.9
>40: stiffer, more powerful

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.

Formula

Ballast / Displacement * 100

42.94
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
323.0
275-350: heavy

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.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
322.95
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
36.6
30-40: moderate bluewater cruising boat

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.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
36.58
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.7
<2.0: better suited for ocean passages

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.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.72
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

From BlueWaterBoats.org:

Introduced in 1986, the Tashiba 36 along with its smaller sibling the Tashiba 31 are the last of the full keel double-enders by designer Bob Perry; he considers them his best. The boat shares many of the innovations Perry made with his Baba 40 design and evolves them further to produce a boat with traits all sailors love. They are fast, close-winded, stiff, and well balanced.

The boats were built by Ta Shing, the best of the Taiwanese boatbuilders and recognized as one of the best quality yards worldwide. Some have described the interior of the boat as a piece of fine furniture.

History

The Tashiba 36 heritage is intertwined with the Baba line of boats. It’s said the name “Tashiba” is probably a play of words, bringing together the name “Ta Shing” with “Baba”. These boats were the brainchild of developer Bob Berg who brought together Perry and discovered the boatyard that was to become the best in Taiwan. The three boat line-up of the Baba 30, 35, and 40 became a hit.

The last of these boats, the Baba 40, eventually got renamed to the Tashiba 40 when Ta Shing took over the marketing and decided to forge ahead with their own line of yachts. Two smaller boats were required to fill out the new Tashiba line.

Having designed the entire Baba line of boats, Perry was the natural choice for the two new boats that became the Tashiba 36 and the Tashiba 31. They were designed together in California with Ta Shing’s Taiwanese representative working closely with Perry.

The Baba/Tashiba 40 having been derived off the lines of the legendary Valiant 40 performance cruiser showed such a marked improvement from Perry’s earlier full keel designs he decided to evolve the design further. Perry writes, “The turn to the bilges got even more firm for increased stability. The bows were finer”. The resulting design produced a boat that sailed incredibly well; fast and close winded enough to challenge many fin keel designs.

Construction

The boat’s hull is of hand-laminated fiberglass. The outer layers employ water and hence osmosis resisting vinylester resin. The interior of the boat is optionally lined with polyurethane insulation. Ballast is a single iron casting encapsulated in fiberglass.

The deck is in GRP and cored with end-grain balsa. In areas where through-deck fittings are bolted, marine-plywood is used as coring and stainless steel backing plates are used.

Variations

The boat was offered in a pilothouse version as well and the standard rear cockpit model. Rear cockpit models have a large stateroom forward and a quarterberth aft whereas the pilothouse has two large staterooms, one forward and the other amidship. The pilothouse has an inside steering station as well as the pedestal steering from the cockpit. Both versions feature a pressurized hot water system with a shower in the head area.

Buyers Notes

As with many of the Baba/Panda/Tashiba boats built by Ta Shing, the Tashiba 36 has black iron fuel tanks which have proven susceptible to corrosion, these tanks have been replaced in many boat but it’s worth checking out. Prices for the Tashiba 36 has remained quite high and generally not many come up on the used market. As of 2010, the asking price is in the range of: $130k-$160k USD
