SP, the marine business of Gurit (Isle of Wight, U.K.), reported on Sept. 22 that it has supplied materials for a newly completed superyacht tender build. The boat, named C-Boat, is unusual for a tender in that an unusual level of design has been put into the project to create a boat that is as graceful, sleek and advanced as the vessel it will serve.

To be officially launched at Monaco Yacht Show this week, C-Boat is a clear-coated carbon fiber composite structure designed by Humphreys Yacht Design and built by Jason Carrington, known as one of the world's most experienced composite boat builders.

The choice of materials used in the build — which started in March 2008 — has ensured that the boat is light, strong and fast, with a maximum speed of up to 45 knots. The boat benefits from a level of composite manufacturing that is said to be unprecedented in a powerboat, and as a result is extremely light, weighing just 1200 kg/2,646 lb, including engines, and is very efficient in terms of fuel consumption. The boat is also notable for a number of unique features, including its shallow draft, waterjets, and modern high-end, sleek finish, and the fact that it was built using a combination of SP's prepregs including SE84 LV, SE70 and SPRINT ST70.

The main prepreg used, SE84 LV, has high compressive strength and is used in large, heavily loaded components. Due to its high-performance properties, it has previously been selected for use by various America's Cup syndicates and boats racing in the Volvo Ocean Race. SP's Corecell, a structural marine foam core for the construction of large, high-performance structures, was also used for the hull, deck and bulkheads and was instrumental in improving the speed of boat production as well as in creating significant weight reduction.
