An innovative solution to modern small boat protection, the Sentry protects your boat both above and below the rub rail, requires a total of 0 knots to attach and is incredibly easy to adjust and adapt. Now that's innovation! No Knots No ropes, no hassle. An integrated strap easily attaches to boat cleats and docks for super fast installation. Traditional fender ropes get tangled and moldy. Sentry does away with rope and incorporates a woven strap featuring DRYLINE technology that stays dry and resists mold. The compact profile of the strap also leaves more space on the cleat for easily attaching dock lines. Hugs Contours Sentry Fenders have a hanging point that's lower than traditional fenders. This allows them to hang at an angle that aligns with the contour of your boat's hull. This keeps Sentry fenders from getting caught on top of the dock. It also looks better. Pass Through The large opening in the front face allows dock lines to pass through in situations where the fender covers the boat cleat. This keeps the lines straight and Sentry aligned and ready for action. Complements Your Boat Styled to mirror the fresh aesthetic of boats today. 4 available colors complement a wide range of boat colors. Maximum Protection An innovative hanging system enables easy positioning on a boat or dock offering protection both above and below the rub rail, unlike traditional fenders.
