A complete list of the details.


Mix the guy who developed the hulls for the trimaran BMW Oracle and Sodebo Ultim, with one of the best race boat builders from Australia and Asia, with the most experienced trimaran spar builder, and the know-how to build sails for thousands of offshore racing multihull miles…to create the ñ53. A  truly fast  cruising trimaran optimized for safety, speed, single-handed cruising. When plugged into handicap formulas the boat appears to be the same as a Formula 40.

Priority design considerations (in order): safety, speed, max reliability, ease of maintenance, least complexity.

Wave piercing bows.  Tiller steering at out board tractor seats. Three rudders. Main hull daggerboard.

Hull #1 cruising grounds: Eastern Maine to Grenada.

On deck, FINN is all business with brilliant white gloss hulls and pilothouse, matte grey crossbeams and rig, and a dark red power blister on the pilothouse roof. Going below down the semi-spiral to port, the color shifts warm with Sepele wood veneers, carbon counters and warm white paint. The true luxury of the boat is the utter silence that is achieved by the whisper wall insulation system throughout the interior.

Whisper Wall: The only way to conquer the hard surface characteristics of modern composite interiors is through a whisper wall system. On FINN, the typical panel system weight was eliminated by using a simple track system which creates very tight surface fabric over 25mm of lightweight adhesive backed foam insulation. A weight study showed that this system was less weight than paint and fairing an interior. The advantage is a soothing very quiet environment under power or while sailing, and a cool temperate atmosphere without the need for AC.

Awning System: FINN sports a bow to stern, ama to ama mesh and canvas awning system that zips to the boom and attaches in as little as 10 minutes to provide complete rain protection and ventilation in winds to 30 kts.  All hatches remain open. This means that in the tropics or extended periods on anchor, the interior temperature stays stable and cool with moving air. At anchor, the cockpit is dry in the rain. The downstream consequence of this awning system is that there are fewer mechanical systems with their weight penalties to maintain, and a far more livable floating home.
