ABSTRACT:
An apparatus for controlling a vessel's horn and automatically sounding navigational signals is disclosed. The apparatus provides a plurality of predetermined horn signals and horn modes, any of which may be selected by pressing an appropriate key on a keypad. The apparatus includes fog modes which will automatically repeat an appropriate horn signal within a predetermined period of time. The apparatus permits a helmsman and other crew members to attend to other duties without constant attention to the vessel's horn.
