A STEERABLE OCEAN FLOOR DREDGE VEHICLE ABSTRACT OF THE DISCLOSURE Disclosed is a dredging system designed and adapted to be towed along the ocean floor via a surface vessel connected thereto by a tow line. The dredge system includes a dredge vehicle, lower tow connector means secured to the dredge vehicle, and positioning means for pivotally and telescopically securing the lower tow connector to the tow line including a tow-line coupling. A first and a second longitudinally reciprocally movable steering linkage means extends between the tow-line coupling and opposing first and second sides of the dredge vehicle. Means are provided for simultaneously but oppositely shortening and lengthening the first and second steering linkages. Thus, the dredge vehicle can be skewed in a first direction relative to the tow line by shortening the first steering linkage, while simultaneously lengthening the second linkage, and thus pulling the first side of the dredge vehicle towards the coupling, and can be skewed in the opposite direction relative to the tow line by shortening the second steering linkage while simultaneously lengthening the first linkage, and thus pulling the second side of the dredge vehicle towards the coupling.
