Abstract
A device for scrubbing algae and other marine growth from boat hulls comprising a one-piece belt of fibrous fluorocarbon abrasive material and a plurality of floats mounted along the belt undersurface. A number of the floats are of oval cross section and are mounted to pivot at right angles to the belt longitudinal dimension. As the belt is drawn in the direction of its length back and forth beneath a hull, the floats urge the belt into frictional scrubbing contact with the hull surface. The pivotal floats operate synergistically to combine buoyant forces and water drag forces to provide enhanced scrubbing contact with surface irregularities such as stabilization chimes.
Claims5
A device for scrubbing marine growth and the like from the submerged surface of boat hulls, especially fiberglass boat hulls of a type having surface irregularities extending lengthwise of the hull, said device comprising an elongated scrubbing belt having upper and lower faces and longitudinally spaced ends, and being constructed of abrasive material, at least the upper of said faces being flat and forming a scrubbing surface, float means constructed of buoyant material extending along and permanently secured to said lower face, and means projecting from said longitudinal ends of said belt and adapted to be grasped by an operator including a closed rope loop extending along opposite longitudinal edges of said belt through at least some of said float means and having loop ends projecting from said opposite longitudinal ends of said belt for manually drawing said belt in the direction of its length back and forth laterally beneath a boat hull with said upper face in engagement with the submerged hull surface, such that buoyant forces exerted by said float means on said belt urge said belt into scrubbing engagement with the submerged hull surface.
