ABSTRACT:
A windvane powered, self-steering device for sail boats of the type employing a steering rudder and trim tab. The windvane pivots about an axis that is tiltably adjustable for light or heavy winds. The windvane axis is also rotatably adjustable with respect to the center line of the sail boat to provide course adjustment. When engaged for operation, the windvane senses the relative ship-wind direction and, when the ship is off course, translates the wind forces on the windvane into corrective movements of the trim tab and rudder to return the sail boat to course. In this operational or steering mode, the self-steering device is characterized by its ability to fully transmit wind power at all angles of tilt of the windvane axis, also, by its ability to be separately adjusted to any desired angle of tilt (wind sensitivity adjustment) or rotation (course adjustment). A preferred embodiment of the self-steering device includes means to initially employ the windvane in a trailing operation to establish a desired steering position for course (trailing mode) and thereafter to employ the windvane in a weathervaning operation for steering corrections (operational mode).
