Date May 4, 1995A boat hull cleaning system, particularly for sail and motor yachts, prevents the contamination of sewers and open waters by recirculating the cleaning water within the system without discharging it therefrom. The system includes a trailerable container, of a size up to the size of conventional, large ocean-going shipping containers, which is fitted with a catch basin having side and end walls that extend upwardly thereon. Hinges between the basin and the walls permit the latter to be folded downwardly into a position in which the walls are downwardly inclined towards the basin. Corner plates connect the adjacent edges of the side and end walls and with the latter form a water drain surface which directs used, contaminated water into the basin. The basin is covered with a water permeable, metal mesh floor which carries supports for holding the boat hull during cleaning. A steam-hot water generator and a used water treatment apparatus are in flow communication with the catch basin and with connectors mounted on the basin for flowing steam and/or hot water through a flexible hose for discharge onto and cleaning of the exterior of the boat hull. Used water is recirculated from the basin and through appropriate piping via the used water treatment apparatus and the steam/hot water generator back to the flexible hose for discharge therefrom as a high pressure jet so that substantially all water can be repeatedly used for cleaning the hull and no water is discharged into sewers or the environment.
