Chock
Chock is a piece of wood or other material put next to cargo to prevent it from shifting.
Chocks are structural reinforcements on ships which guide the mooring lines to and from the shore / other vessels. Chocks need to be of a much higher SWL than the mooring line to avoid structural damage and withstand various forces when a vessel is moored.
