This summer sailors on Lake Ontario will see an exceptional new multihull take to the water. This Catamaran, which has been built near Toronto, pushes back the boundaries of performance cruising further than has ever been attempted before. Furthermore this boat is intended as a test bed for an exciting new range of yachting instruments of manufactured by Tektron Equipment Corporation, and will therefore provide more data than has ever been gathered on a multihull before, in terms of rig and hull stress against performance on all points of sail, and sea states. After tuning up on Lake Ontario, the Tektron 50 is entered in the 1988 Quebec-St Malo race. Read more

I have been asked many times to talk about Performance comparisons and Rating Rules, so I will begin by discussing some of the ideas that went into the new MOCRA rating rule.

Over the last few years I have seen many questions (published in various yachting magazines) regarding multihull performance, and as a designer I am invariably asked 'how fast will she go?' and 'what is the weight carrying capacity?'.

This Paper evaluates how a multihull performs in waves with respect to rolling and pitching. Stability is evaluated both in relation to wind and wave action. In particular reference will be made to Prof. Marchaj's recent work - 'Seaworthiness the Forgotten Factor.' Multihulls are studied under the same criteria as monohulls are evaluated in the book, giving a clear comparison between old and new multihull designs, and monohulls, particularly with regard to capsize in wind and waves. Other factors affecting seaworthiness, such as pitching, surfing, rolling, yawing etc, are discussed. Read more.

Many people wonder about what the benefits of ocean races are to ordinary sailors. Races like the OSTAR and La Route du Rhum, where enormous sums of money are spent on the latest technology, materials, and systems, to assist the shorthanded sailors to sail boats as fast and as safely as possible.

All yachts must work in harmony with the sea: both in flow and in motion. The boat that does it best, and harnesses the forces of nature to her advantage (rather than opposes them), will surely be faster for it.
