Mooring Chock

A mooring chock is a fitting with a gap at the top, through which a rope or line is run. The mooring chock on this page is called a bulwark mounted chock. It is a round or oval shaped cast steel component that is usually embedded into the bulwark of ships. As the contact area of the ship chock and the mooring rope is a circular arc shape, the cutting action of the bulwark to the mooring ropes in prevented. By doing so, the mooring rope and the eye splice can run through the chock easier. Mooring chocks are essential deck fittings for different ships and vessels.
