Ed Horstman designs started in 1960 with the TRI-STAR 40. In 1966, it was the first trimaran to race in the Transpac and took second place! The TRI-STAR 38's fine sailing features are complemented with high under wing clearance and full bouncy amas that are spaced to reduce wave interplay. The TRI-STAR's flush deck unitized construction gives strength and maximum interior accommodations and the safety of an uncluttered deck for lounging and easy sail handling area for the most inexperienced of sailors. True windward performance is achieved with raisable high aspect ratio dagger boards in each ama. Horstman trimarans are usually home built, but this one was built by a seasoned shipwright in Seattle.

Description

Draft 3.5’, beachable with reinforced keel and retracting daggerboards

6’3” headroom throughout vessel

Sleeps 6 in three areas. Port and Starboard double wing berths with privacy curtains and aft cabin V-berth

bow-to-stern: anchor locker, head with sink, on-demand hot water shower, nav station, wing deck storage both sides, full height closet with many shelves for crew, salon with fold-down table and window to the water, galley, engine room below cockpit, aft cabin

bow-to-stern: dinghy and running rigging locker, waterproof bulkhead, standing height workshop with tools, supplies and spares, quarter locker with water hoses, electrical cords and emergency Whale manual bilge pump

bow-to-stern: sail and additional anchor tackle locker, waterproof bulkhead, standing height flexible storage space with bins full of fishing gear, sanding and painting supplies, sailmaker and canvas makers tools and supplies, engine and driveline servicing tools and supplies, quarter locker with water jugs, fenders, dock lines and chafe gear, four PFDs

Scooped bows allow easy tacking, excellent watchkeeping, make docking easier, and funnels a breeze down the hatches.

Three large Lewmar Ocean Series deck hatches provide excellent ventilation

Full beam solid decks and minimal nets make for the safest deck working area, allowing sail handling and boat projects to be done on deck, and transfer all rig and wave loads through the entire structure rather than just through crossbeams

All transitions from one area to another are one step. One step from galley to cockpit. One step from cockpit to outer cockpits and one step from outers to deck.

High bridge deck clearance minimize wave pounding and sneezing.

Batteries are located high in the cockpit seating, keeping them out of the bilge and engine room. Maintaining power if the hull ever floods.

The moulded swimstep and handles in the transom make getting in and out of the water easy.

Built to be self-serviceable and self-reliant, everything is accessible and serviceable.

Built by a seasoned shipwright in Seattle, Robert Braggins built three of these Horstman trimarans. This hull was his personal yacht for 15 years.

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)
