ABSTRACT:
Apparatus for shielding the submerged portion of a moored water vessel, such as a boat hull and driving gear, from direct contact with water. The apparatus protects the hull and driving gear from marine growth, electrolysis, water deterioration of underwater hull fittings and driving gear, fiberglass hull blistering, wood rot, and water leakage. The preferred form of the assembly includes a rigid frame which is secured to support brackets which are attached to a boat dock. This frame is larger than the perimeter of the water vessel hull above the water line. The rear of the frame includes a gate which is attached to the front portion of the frame by horizontal lag bolts. Attached to and dangling below the frame and gate is a water-impervious bag which is larger than the underwater portion of the water vessel. Gate lines which extend from the gate to cleats on the boat dock are lowered, thus lowering the gate to allow the water vessel to enter the bag. Then the gate lines are raised, thus raising the gate above the water line so that the hull is enveloped by the bag below the waterline. The bottom of the bag contains a low area containing an electric water pump with a water evacuation hose running to the outside of the apparatus. When the water pump is turned on, it will pump out the water which is inside the bag, leaving the boat hull floating, but shielded from direct contact with water. The vessel exits the enclosure by lowering the gate lines which lower the gate.
