Mooring Cross Bitts have two types, single bitt and double bitts, it is a system for connecting and disconnecting tugboats onboard mercant vesels. The system can be installed on all types of vessels and the main purpes whith the system is to help the crew and owner to reduce the risks and difficulties during the operation. 


Shipboard bitts aboard wooden sailing ships (sometime called cable-bitts) were large vertical timbers mortised into the keel and used as the anchor cable attachment point. Shoreside bitts are carefully manufactured and maintained to avoid any sharp edges which might chafe and weaken the mooring lines.


Mooring lines may be laid around the bitts either singly or in a figure-8 pattern with the friction against tension increasing with each successive turn. As a verb bitt means to take another turn increasing the friction to slow or adjust a mooring ship's relative movement.
