High Modulus to Engineer the Largest all-Composite Motor Yacht

21 January 2008

High Modulus has begun the structural engineering design of the largest all-composite motor yacht ever built.

The 186ft (57m) vessel will be a vacuum-infused production motor yacht, and will be the first composite motor yacht to break the 500 gross ton threshold. These exciting ‘firsts’ are the work of Christensen Shipyards, headquartered in Vancouver, Washington. Christensen have been building fibreglass motor yachts between 47m - 50m (157ft-164ft) for over 20 years, and this new Custom 186 Series will offer similar features to the Custom 160 Series.

Despite all Christensen boats to date having been built in Vancouver, these impressive 186ft yachts will be constructed in a brand new, purpose-designed facility on a lakefront in Tennessee.

High Modulus is part of an international team that has been brought together to develop this landmark project. The company’s role is to develop all composite structural specifications, and to work with the yard and other consultants to ensure the challenging objectives are met. In particular, High Modulus will liaise with Flag and Class officers, as well as noise and vibration consultants, to deliver a yacht that meets noise and class requirements within a high-performance yet practical structural solution.

Tooling will start in early 2008 and the first boat, for current Christensen yacht owner John Rosatti, is due to launch in 2011.
