The Harbour Master operates a Harbour Patrol Launch service within the limits of the Port of Southampton throughout the year. This service is mainly used to escort large commercial vessels safely into or out of the harbour area to ensure that the main navigable channels are kept clear for the safe transit of these ships.
The Harbour Patrol launches maintain a VHF R/T listening watch on channel 12 (call sign Southampton Patrol) and their crews will be pleased to offer advice on the Harbour and Approaches on request.
These vessels, having a royal blue hull with white upper works, are easily recognisable by the broad yellow stripe on each side of the bow. At night, in addition to steaming lights, each carries an all round blue light at the mast head.
