ABSTRACT:
An automatic pilot for a sailboat includes a mode switching arrangement which permits a person to operate the sailboat in any one of several modes. One is the STEER mode, a second is the OFF mode, a third is the STANDBY mode, a fourth is the WIND mode and a fifth is the COMPASS mode. Another switching arrangement enables either the WIND mode or COMPASS mode to be operated in COURSE CHANGE sub-mode manners. Various mechanisms and circuitry further are included to enable the sailboat to be manually steered, to stabilize the rate of change of rudder position, to null a control that is a function of the change in heading error, to wash out certain signals under certain conditions, to inhibit certain signals under certain conditions, and to provide a steering command that furnishes a visual direction to the steersman when the automatic pilot is in a COURSE CHANGE sub-mode.
