Abstract: A boat hull cleaning apparatus having a plurality of uniquely designed brushing units is disclosed. The apparatus comprises a plurality of brushing devices each device being disposed in an associated housing. The brushing device comprises a rotatable base member having an axis of rotation, and a plurality of cleaning bristles extending outwardly from the base member. The bristles are disposed on the base member so as to be substantially parallel to the axis of rotation. A motor is disposed in the housing having a rotatable shaft. The brushing device is disposed at one end of the shaft and a propeller is disposed at the other end of the shaft. Rotation of the shaft causes (i) the propeller to drive the housing toward the boat hull; and (ii) the base member to rotate about its axis. The boat hull cleaning apparatus of the present invention has particular utility in thoroughly cleaning various shaped boat hulls and removing tenacious growths therefrom.
