Avoid mooring lines hitting and rubbing on your boat with Accon Marine’s 500 Series Pull-Up Line Chocks. The chocks come in two sizes, 4.5 and 6 inches, to accommodate different rope sizes. They also come in different models depending on intended location: Port, starboard, or stern. What’s special about these is that they retract flush into the deck so you won’t even know they’re there. Install the chocks onto a brand new boat or by yourself. All it takes are two screws and a drain cup. Get your own single stern chock for $70.27, or a pair starting at $140.54.
