Stopper
In maritime context, a stopper is a device used to secure a line or rope in place. It is typically made of metal or wood and is designed to prevent the line from slipping or running out. Stopper knots are also used to secure lines, particularly when tying off to a cleat or bollard. Stopper knots are tied at the end of a line and are designed to prevent the line from slipping through the cleat or bollard. Stopper knots are commonly used in mooring operations to secure a vessel to a dock or pier.
