The described invention is intended for use primarily in the yacht repair industry and specifically in the repair of fiberglass hulls of yachts. However, its use will not be limited to fiberglass in yachts but fiberglass in general where applicable. The invention removes gelcoat (coating over fiberglass) and/or consecutive layers of fiberglass laminate. The invention is specifically designed to remove osmotically blistered gelcoat and/or fiberglass laminate in an efficient and in an environmentally attractive fashion. The invention "planes" off gelcoat and/or fiberglass laminate duplicating the existing contour of the hull or boat bottom. The cutterhead is continually flushed with water to prevent toxic dust from being released into the air. Interchangeable depth gauges allow change in the depth of the cut. Gelcoat and fiberglass are removed anywhere from a 0 to 1/4 inch depth at a rate of four square feet per five minutes leaving a consistent and fair surface.
