Abstract:
1. An underwater plow having negative buoyancy so that said underwater plow sinks when said underwater plow is placed in water, said underwater plow further comprising: a frame having a plow end and a float end; a plow assembly attached to said plow end; a propulsion assembly attached to said float end, said propulsion assembly providing a propulsion force F said propulsion assembly having at least one float and at least one propulsion means that is rigidly coupled to said float, said float providing sufficient buoyancy so that said frame establishes a rake angle β with an ocean floor when said plow end contacts said ocean floor; and, said propulsion assembly and said frame connected at a pivot point such that when said underwater plow contacts an obstacle on said ocean floor, said frame pivots about said pivot point and decreases said rake angle β during application of said propulsion force F
