  • Boat hull having the capability of installing an optional transducer
    Patent number: 5697319
    Abstract: A removable form is positioned within a boat hull and may be removed to optionally install a sonar transducer and a method of optionally positioning a sonar transducer within a boat hull after the hull is fabricated. The removable form is defined by a distal end and an opposing proximal end. The proximal end includes a retaining flange extending beyond a nominal thickness of a portion of the hull for anchoring the removable form within the boat hull. The distal end is substantially flush with the outer surface of the hull. The removable form is temporarily adhered to a boat mold and the hull is formed therearound. When the hull is hardened, it is removed from the mold with the removable form secured therein. The hull is operative in this condition, or the removable form may be removed and a sonar transducer may be positioned in its place.
