ABSTRACT:
An apparatus for shielding the keel and/or bow of a watercraft is disclosed in one presently preferred embodiment comprising a protective cover member having an elongated body substantially tapered in cross-sectional thickness from a midsection to at least two opposing sides. Protective cover member is preferably configured having one or more elongated channels formed therein. Preferably, the elongated channels are integrally formed in an exterior surface of the protective cover member and longitudinally disposed substantially parallel to the linear length of the protective cover member from a first end to a second end thereof. The protective cover member is preferably formed having an opposing contacting surface comprising a fastening means preferably disposed thereover for securing the protective cover member over the keel and/or bow of the watercraft. In current design, the tapered cross-sectional thickness of the body of the protective cover member in combination with the configuration of the elongated channels formed in the exterior surface of the protective cover member preferably provides means for creating turbulence in the water by forming pockets of air in the water which promote a hydroplane effect against the body of the watercraft, thereby improving the hydrodynamic flow of water across the keel and/or bow of the watercraft.
