Abstract
Auxiliary control of fluid actuated steering apparatus for ships, boats and the like (hereinafter, 'water vessels') includes isolating the existing steering control system from the steering apparatus and providing flow-communication between fluid under pressure and the steering apparatus through an auxiliary directional control sub-system enabling control of the steering apparatus independently of the main steering control system. According to a preferred embodiment, the source of the fluid includes a quantity of fluid stored under pressure and another quantity of fluid adapted to be provided under pressure. Isolation of the existing steering control system is carried out by coupling the source of fluid to a by-pass control sub-system preferably adapted both to isolate the main steering control system and to couple the auxiliary directional control sub-system to the steering apparatus. Initiation of the auxiliary steering control may be carried out by electrical, hydraulic or pneumatic actuation or, preferably, by a combination thereof.
