About The Boat


Mix the guy who developed the hulls for the trimaran BMW Oracle, 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.
