How to Make a Mooring Line

Boats dropping anchors can be tremendously damaging to coral and life below the surface. If you install a mooring buoy connected to a permanent anchor on the bottom, your boat doesn't have to drop an anchor but can still secure itself and avoid drifting. This can dramatically reduce damage to underwater ecosystems. You must make sure that the anchor you use for the mooring line will not be dragged by the boat and cause more damage.

Instructions

    • 1

      Make a concrete block by pouring concrete into a mould and allowing it to set around a steel ring, with half of the ring out of the block. The Frederiction Yacht Club recommends a block sized 4 feet by 4 feet by 18 inches.

      Feed the rope through the ring on the concrete block. Feed a cut section of fire hose over the loop to avoid the rope chafing against the ring. Make a loop in the rope behind the ring. Feed the loose end of the rope through the loop, around the neck and back through the loop. Pull the resulting bowline knot tight.

    • 3

      Wrap another section of fire hose around the knot. Secure it in place with cable ties.

      Attach the other end of the rope to a swivel with a bowline knot. Attach a shackle to the other end of the swivel. Secure the shackle to a mooring buoy.
