Nautical Term: Chock roller
Definition of Chock roller
A chock roller is a maritime device, specifically a type of chock. It is designed with a sheave or groove to prevent chafing of ropes as they pass over the device. This is particularly important in heavy seas or when using large ropes, as chafing can cause damage and reduce the effectiveness of the rope.
For example, when securing a large sailboat during a storm, the crew might use a chock roller to prevent the mooring ropes from chafing against the boat’s hull or the dock. By using a chock roller in this way, the crew can ensure that their mooring ropes remain in good condition, and that the boat is securely tied to the dock, even in the roughest seas.
