Abstract (en)
[origin: EP0373913A1] An improved keel arrangement for sailing vessels, comprising a hydrofoil surface (10) mounted for rotation about an axis (4) parallel to the vessel's centreline and capable of producing a hydrodynamic lift force acting in a direction perpendicular to its axis (4) of rotation, the hydrofoil surface being selectively orientable to vary the direction of the lift force with respect to the vertical. Preferably two such hydrofoil surfacs (10L, 10W) are provided, so that their lift forces may be oriented to provide a net windward force and a righting moment to the vessel (3).
