<p>A yacht (10) includes a mast (12) that is mechanically connected to a keel (14) via a bearing (16), located in the base of hull (18) of the yacht (10). A sail foil (30) is pivotally mounted to the top of the mast (12) via a rotating bearing (34). In use, as the wind forces the sail foil (30) and mast (12) to leeward, a corresponding movement to windward is induced in the keel (14) and thus the yacht's hull (18) can remain substantially horizontal with respect to surrounding flat water.</p> |
