Abstract

A steering system for steering a personal water craft when a high velocity water jet which is used for propelling and steering said water craft is cut off by an engine failure. In a first embodiment, a rudder is pivotally mounted on a nozzle for rotation about a horizontal axis between an elevated non-operative position and a lowered operative position. In a first embodiment, the rudder is automatically raised to the non-operative position by an impingement of the water jet on a baffle on the rudder. When an engine failure occurs, the rudder is automatically lowered to the operative position by hydrodynamic and gravitational forces which act on the rudder. In the operative position, braking forces are generated by a fin on the rudder. In a second embodiment, the rudder is manually elevated to a non-operative position and manually lowered to an operative position by a link or a cable.
