Protects your boat hull during loading, launching and transport Rubber bow stop assembly includes a soft rubber roller, Vframe bracket and mounting hardware sized for 1/2' (13.5 mm) shafts. The rubber roller absorbs contact at the bow, reducing wear and stress on fiberglass, aluminum and inflatable hulls. Durable, impact‑absorbing construction Soft rubber face minimizes scratches and dings to kayaks, canoes and small boats while guiding the bow into place. Componentry has been tested under pressure to resist deformation and maintain integrity. Two bracket size options for secure mounting Available dimensions: 170 × 83 × 110 mm and 166 × 18 × 82 mm. Mounting apertures: 14 mm (0.55') and 13.5 mm (0.53') to fit common trailer frames and hitch setups. Vframe bracket provides stable support and simple attachment to trailer crossbars or winch stands. What makes this product useful Prevents concentrated impact damage during repeated launching and retrieval. Simple, hardware‑included installation for retrofitting most general trailer frames. Suitable for use with kayaks, canoes and small boats that rely on bow rollers for alignment and support. Typical applications Loading a fiberglass day boat onto a trailer at a launch ramp to avoid chipping the bow. Transporting a canoe or kayak over long distances where repeated vibration and movement could abrade the hull. Securing an inflatable boat on a trailer where soft contact surfaces help prevent punctures and pressure damage.
