The ITD5301 Weld-On Bow Chock is made out of marine grade Billet aluminum. The Fish Fighter™ Products Weld On Bow Chock is a must for any serious anchor fisherman. By using our Bow Chocks, you can Chock your boat over to Port or Starboard while on anchor. It’s your choice on how many you want to use. These bow chocks have a compact design that takes up very little bow space. They have a sleek, clean aluminum look and can be welded to any aluminum surface. Each Bow Chock is CNC machined to allow the rope to slide around without chafing while still holding it down to the boat and in the desired position. Our Bow Chocks also work great as a grab handle and extra method to cleat your boat off. (These are the Bow Chocks we use on our 23 ft Precision Weld Jet Boat) Note: each Bow Chock has a Structural Rating of 2,000lbs, but is limited to the surface it is mounted to. Anchoring can be very dangerous so please read our complete instruction manual before use.
