Abstract:

A system for inhibiting growth of barnacles and other marine life on the hull of a boat. The system includes a plurality of transducers or vibrators mounted on the hull and alternately energized at a frequency of 25 Hertz through a power source preferably the boat battery, and a control system. The system has two selectable operating modes one being continuous and the other being periodic. Also when the voltage of the battery falls below a predetermined level, transducers are automatically de-energized to allow charging of the battery after which the transducers are energized.
