The Telstar 28 Trimaran is a trailerable trimaran with great sailing performance complimented by good motoring capability. Her outriggers extend to an 18’ beam providing safe, stable and comfortable sailing.
She combines optimal hull shapes, a performance rig, a convenient deck arrangement and a roomy cockpit - all with a large and comfortable interior.
The salon has a full 6’ of headroom. A large teakwood table with comfortable seating for 6 adults is on the port side. A convertible sofa is on the starboard side. Up forward a separate head provides privacy.
The galley is located on the port side with a sink, two burner stove with broiler (LPG). Opposite the galley is a navigation station with space for a 12v cooler.
She features a Telstar Mast raising System - a patented triple “A” Frame Mast Raising/Lowering System. A Bow Sprit - 4’ Extendable Bowsprit with white spinnaker.
Rigging features include an Asymmetrical Spinnaker (590 square feet), Roll-Gen Roller furling Spinnaker system with lines led aft, Schaffer Adjustable Genoa Cars with lines led aft, Adjustable Main Sheet Car with continuous line and cam cleats, Mast Climbing ladder system, Ama retraction system with lines led aft with jam cleats, Bungee and clips to prevent Ama cables from entering the water when Amas are closed, Sender line from rudder to rudder raising system should a line need to be replaced, Main with Sail Cover, and a 150 Roller Furling Genoa.
Armstrong Hatches and deck plates replace the original Bomar ones.
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
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
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
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
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
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 Beam1.33)
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)
An entirely new TELSTAR model (2003). (An earlier TELSTAR 9M was also designed and built by Tony Smith until about 1980.)
This version is ‘foldable’ reducing the beam from 16.0’/4.8m to 8.5’/2.6 m) for road transport and easier mooring where space is restricted. The Double-hinged beams swivel the amas alongside the main hull without extending the boat’s overall length.
