Traditional round fenders protect hulls fairly well, but not gunwales. Ski boats, bass boats and runabouts with step-down gunwales are especially vulnerable to damage from docks. The HULL HUGR Contour Fender hinges to wrap around the gunwale and hull, following the contours of the boat. It is contructed of incredibly durable tri-laminate material with polycarbonate grommets. It stows conveniently under seats or inside storage compartments.
