PCT No. PCT/SE85/00413 Sec. 371 Date Jun. 25, 1986 Sec. 102(e) Date Jun. 25, 1986 PCT Filed Oct. 23, 1985 PCT Pub. No. WO86/02614 PCT Pub. Date May 9, 1986.A wind vane steering gear for a yacht comprises a bracket adapted for attachment to the transom of the yacht, a rocker which is pivotally movable on the bracket about a rocker axis in the longitudinal vertical center plane of the yacht, rudder coupling tackle connecting the rocker with the yacht rudder, a servo oar mounted on the rocker and pivotally movable therewith and rotatable relative to the rocker about an oar axis perpendicular to the rocker axis, and a steering arm which is provided with a wind vane and pivotally mounted on a support member carried by the bracket with the pivot axis situated in the same plane as the rocker axis, the steering arm being coupled to the servo oar by a linkage so that pivotal motion of the steering arm causes the servo oar to be rotated and thereby, under the action of hydrodynamic forces, to be pivotally moved together with the rocker about the rocker axis. The wind vane is adjustable to different positions by means of an actuating member at the upper end of the steering arm. |
