All ships over 50 gross tonnes or 20m in length carrying more than 12 passengers entering the harbour take a pilot on board 1 nautical mile due south of the west pier. The pilot cutter precedes the vessel into the harbour.
During the act of pilotage the harbour is closed to all other vessel movements. This is announced on VHF 71 by the pilot. An announcement on VHF 71 is also made by the pilot when the harbour is re-opened.
Whilst all ships are required to have a pilot on board, the pilot is not in command of the vessel. This responsibility remains with the Captain of the vessel. The pilot is there to advise the Captain so that the ship navigates safely into the harbour.
Most ships are well found and their equipment functions correctly, however failures and malfunctions can occur. Skippers of leisure craft must be alert to harbour announcements and give ships a clear passage.
