If you are looking for an exciting cruiser for day sails or a platform to cruise along the coast, you have found it with this 1978 Norman Cross 36 MK II Trimaran. Classic design by Norman Cross who was strongly influential in the refinement of designing multihulls in San Diego, California.
Cross introduced the 34 and provided a stretched version 36 MK II to take a step up from the traditional “cruiser” model designed for a higher potential of speed without getting into racing.
Two large berths on port and starboard, a centralized salon and forward storage and head. The galley has an electric mini-fridge, foot pump sinks and counter space for your navigation charts, radio and other equipment of your choosing.
The head is pleasantly designed to do the basics without the odor or muck of holding tanks.
This trimaran is perfect for the minimalist with the true basics and functional life of sailing on the water.
With 6’ 1” head clearance, there is easy movement forward or aft without crowning your head when maneuvering below deck.
Plenty of self-reliant power with the two Kyocera marine grade solar panels.
The seller has done over $12,000 in newer hull and deck paint and other improvements.
Per the previous owner, the inboard engine was seized and costly to repair due to limited parts. The inboard engine and fuel tank have been removed. She is powered with the simplicity of a 9.9 HP outboard and customized motor mount.
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 √LWLA 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)
