DH550 Catamaran - US$1,000,000

This is a big and powerful boat and it is intended for cruising the oceans of the world. To take on that role, it has 1m (39") bridgedeck clearance to minimize slamming in big seas. The hull/bridgedeck junction has received particular attention to ensure that the loads imposed by rig and ocean are properly transmitted and shared between them. Carbon composite chainplates are laminated to the inside and outside of the hull and spread the rigging loads down into the hull skin, longitudinals and bulkheads.

The mast stands on top of a major transverse bulkhead that is configured as an I-beam to spread the compression load laterally into the hulls and is tied into longitudinal bulkheads that spread the load fore/aft into the bridgedeck structure.

Photos are of hull #4 "Spice". This boat (Hull #4) is currently under construction, expected completion summer 2009.
