The water-ballasted, all-carbon C-Boat...

Design

She’s good for 45 knots in flat water and, yes, for the rougher stuff, performance is boosted by pumping up to 250 litres of water into a bow tank. That weight forward allows her to punch more effectively through waves.

OCTOBER 2009

British grand-prix raceboat builder Jason Carrington got Rob Humphreys’ HYD team to design the new 9m (30ft 6in) model for him.
She’s pushed along by twin 230 Alamarin water-jets and was laminated using SE84 carbon prepreg over Nomex honeycombs and Corecell.
She’s got a deep-vee hull and long waterline length ‒ achieved with a vertical stem and careful design around the water jets to ensure minimum losses, plus the ballast system that delivers weight forward when needed.
The C‐Boat was on public display as a support boat for Edmiston throughout the 2009 Monaco Yacht Show. She’s said to be the first of new range of similar craft.
