Is it true you have designed a canting keel yacht for the Formula 100 – Open One Metre (F100) class rules?
A Yes. This project was commissioned by Doug Lord of Florida, USA so that he can add a canting ballast twin foil (CBTF) yacht to the range of yachts offered by microSAIL – see www.microsail.com. The CBTF concept has been patented by DynaYacht with whom Doug has a commercial agreement allowing him to use the technology on RC yachts. In essence, in a CBTF yacht, the normal fixed fin and ballast is replaced by a canting strut and ballast. By canting the strut and ballast to one side or the other stability can be matched to the heeling moment and the hull can be sailed upright. The relatively large angle that the strut makes to the vertical means it is inefficient at generating side force to resist the side force of the rig. So the strut’s only task is to support the ballast with a very low drag. Ability to generate adequate side force and steerage is achieved by using twin rudders, one being placed ahead of the strut and one being aft. Each is larger than the normal single rudder. Steerin
