The Barefoot International Gunnel Mount Barefoot Boom is designed to work on outboard and inboard outboard boats that do not have a factory mounted ski pylon to clamp a boom on. Barefoot International Deluxe Booms are the world's only solid 100% aluminum booms. This helps prevent dangerous spring back. These booms feature easy on/off quick release, cut-down knurled grip, and cut-down rope holder. Come with gunnel saver, boom pad, and 100% stainless steel hook and cables. All adjustments to these booms are made inside the bow protector eliminating clamps and turnbuckles. Gunnel Mount Boom - Can be attached to virtually any boat - inboard, outboard, or I/O.
