ABSTRACT:
The invention is a marine growth wiper and method of wiping for a waterborne object. The wiper includes at least one cord and a device for positioning the cord so that the cord is located below the waterline and within wiping distance of a submerged surface area of the waterborne object. With this arrangement, any water movement will cause the cord portion to wipe across the submerged surface area to remove primary marine growth therefrom. The wiping action is enhanced by utilizing a plurality of the cords either spaced from one another with respect to the surface of the object or attached to the object at a common location. The cords may be either positively or negatively buoyant depending upon the manner of their positioning. The method includes providing a plurality of such cords, positioning the cords so that the cords will wipe across the object, and suspending the cords free in the water so that water movement will activate the cords to wipe across the object.
