High Modulus to engineer largest all-composite motoryacht

9th January 2008

High Modulus has begun the structural engineering design of the largest all-composite motor yacht ever built. This 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 benefits to the Custom 160 Series, such as owner specified superstructure, window shapes, hull colours and interior selections, but always relying upon a proven hull and systems.

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 and has been tasked with developing all composite structural specifications.

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