What are bitts used for on a ship?

Bitts are specifically designed to secure mooring lines on a ship. They are cylindrical posts or fittings, often made of steel, that provide strong anchor points for ropes and lines used during docking and undocking maneuvers. By securing the mooring lines to the bitts, crews can effectively control the ship's position at the pier or within a harbor, especially in adverse weather conditions or strong currents.

This use of bitts is critical for ensuring the ship remains safely moored and does not drift away from the docking point or collide with other vessels or structures. Their sturdy construction allows them to withstand the tension and forces exerted by the mooring lines, making them an essential feature in maritime operations.
