ABSTRACT:
A control apparatus is disclosed for a sailboat automatic pilot comprised of a rotatable drum connected to a compass member, the drum having a series of light-reflective and light-absorbent stripes. A light source located adjacent to the drum illuminates the drum surface. A pair of light detectors provide signals to circuits which detect the transition between the light-reflective and light-absorbent stripes and determine the direction of rotation of the drum to provide corrective signals to a steering actuator.
