ABSTRACT:
An improved, personal, submersible marine vehicle with a fluid-tight elongated hull having an open back and a removable cover. Within the hull is a battery compartment. A shrouded propeller and motor depend from the hull. A dense, rigid cellular foam section fills substantially all of the air space in the hull and surrounds the battery compartment. Electrical speed control means for the motor are embedded in the foam section so that the battery is shielded from contact with any source of spark in the electrical control means. Further, the foam section provides a substantially greater effective hull thickness than the actual thickness of the hull so that the vehicle can be safely used at far greater depths. Also, the foam section renders the vehicle substantially leak-proof.
