The resultant angular displacement of the wind vane is transmitted to a servo-tab of a rudder, the servo-tab in turn undergoing a corresponding angular displacement; so that the new rudder orientation varies the boat heading. The self-steering system further comprises a clutch for engaging and disengaging the system while setting a new course. The system also comprises means for raising the rudder out of the water.，下面是Self-steering system专利的具体信息内容。
1. A self-steering system for a boat, comprising; a hollow symmetrical wedge shaped wind vane mounted on said boat, said wind vane adapted to undergo angular displacements; a rudder comprising a body portion pivotally mounted with respect to said boat, and further comprising a servo-tab pivotally mounted on said body portion of said rudder; transmission means for transmitting said angular displacement of said wind vane to said servo-tab of said rudder to produce a corresponding angular displacement of said servo-tab; clutch means for engaging and disengaging said wind vane and said rudder; means for causing the underwater waterflow pattern to produce an increased water pressure on the exposed surface of said angularly displaced servo-tab, and to thus cause the increased water pressure to pivot said body portion of said rudder relative to said boat; whereby the power for pivoting said body portion to said rudder is obtained from the underwater waterflow pattern, and not from said wind powered wind vane.
2. The combination of claim 1 wherein said servo-tab and said body portion of said rudder are positioned with their upper ends slightly above the water level.
3. The combination of claim 1 wherein said transmission means comprises a first clutch element adapted to pivot with said wind-vane, and further comprises a second clutch element adapted to engage said servo-tab.
4. A self-steering system for a boat, comprising: a wind vane mounted on said boat, said wind vane adapted to undergo angular displacements; said wind vane being of a hollow symmetrical wedge shape, having a frame and cover therefor, said frame having a plurality of normally hidden permanent arms that can be exposed to a stiff wind by removing said cover from said frame; a rudder comprising a body portion pivotAlly mounted with respect to said boat, and further comprising a servo-tab pivotally mounted on said body portion of said rudder; transmission means for transmitting said angular displacement of said wind vane to said servo-tab of said rudder to produce a corresponding angular displacement of said servo-tab; means for causing the underwater waterflow pattern to produce an increased water pressure on the exposed surface of said angularly displaced servo-tab and to thus cause the increased water pressure to pivot said body portion of said rudder relative to said boat; whereby the power for pivoting said body portion of said rudder is obtained from the underwater waterflow pattern, and not from said wind powered wind vane.
