Bundock and Ashby together with 'Coach', Mike Fletcher, discussed the idea over 18 months ago and know that it could generate a lot of horsepower at low speed.

Ashby, a sailmaker, soon had one designed on his laptop, which they built. In addition they constructed the special snuffer and reinforced bowsprit within the class rules, and are thus ready to match the opposition.

Bundock commented: 'It takes quite a bit of time to work out the sail handling.'
