Abstract
A dredge vehicle having remote steering for moving on the ocean floor on a skid surface, or preferably a pair of runners. The steering is provided by a steering member extending downwardly below the bottom surface of the skid surface into the mud on the ocean floor, which can be moved so as to vary the resultant sideways force exerted against a surface of the member. The movement is provided by pivotally connecting the steering member to the dredge vehicle about a vertical axis. Specifically, the steering member can be rotated by an hydraulic cylinder. Preferably, the downwardly extending steering member is also vertically movably secured to the dredge vehicle so as to be able to be pushed upwardly and out of the way should the steering member strike against a submerged, hard-surfaced object. Preferably, at least a pair of pivotable steering members disposed in tandem are provided.
