High Modulus (Hamble, U.K.) announced in January that it is working with Christensen Shipyards (Vancouver, Wash.) on the structural engineering design of what is expected to be the largest all-composite motoryacht ever built. The 186-ft/57m vessel will be a vacuum-infused production motoryacht and reportedly will be the first composite motoryacht to break the 500-ton gross weight threshold.
Christensen has been building fiberglass yachts for 20 years, producing craft ranging from 157 ft to 164 ft (47m to 50m) long. The new 186-footer will be part of the Custom 186 series; owners will be able customize the design of the superstructure, window shapes, hull colors and interior selections.
The boats will be produced at Christensen’s new 55-acre purpose-built facility on a lakefront in Tennessee. High Modulus is part of an international team assembled to develop the yacht. It will develop all composite structural specifications and liaise with Flag and Class officers as well as noise and vibration consultants, to deliver a yacht that meets noise and class requirements. Tooling will start in early 2008, and the first boat, for current Christensen yacht owner John Rosatti, is due to launch in 2011.
