ABSTRACT:
A screw-rudder assembly is mounted at the bottom of a steering shaft which rotates in a tubular casing which is mounted on slide shoes which slide in vertical slide guides fixed to a support which is mounted on a floating vehicle. A power cylinder connects the tubular casing to the support and slides the casing upwardly to regulate the depth of immersion of the screw and pivots the casing upwardly about upper slide shoes when bottom slide shoes are released through passages in the slide guides, to lift the screw-rudder out of the water.
