English law, by section 742 of the
Merchant Shipping Act 1894 (
57 & 58 Vict. c. 60), a pilot is defined as "any person not belonging to a ship who has the conduct thereof"—someone other than a member of the crew who has control over the speed, direction, and movement of the ship. The
Pilotage Act 1987 governs the management of maritime pilots and pilotage in harbors in the
United Kingdom. Pilots are required to have maritime experience prior to becoming a pilot, including local knowledge of the area. For example, the
California Board of Pilot Commissioners requires that pilot trainees have a master's license, two years' command experience on tugs or deep draft vessels, and pass a written exam and simulator exercise, followed by a period of up to three years' training, gaining experience with different types of vessel and docking facilities. Following licensing, pilots are required to engage in continuing educational programs. Typically, the pilot joins an incoming ship prior to the ship's entry into the shallow water at the designated "pilot boarding area" via
helicopter or
pilot boat and climbs a
pilot ladder, sometimes up to , to the
deck of the largest
container and
tanker ships. Before climbing the pilot ladder, the pilot performs a visual inspection of the boarding arrangement to confirm it is safe to use and in accordance with international requirements. As both the ship to be piloted and the pilot's own vessel are usually moving this may be dangerous, especially in rough seas. With outgoing vessels, a pilot boat returns the pilot to land after the ship has successfully negotiated coastal waters. Pilots are required by law in most major sea ports of the world for large ships. Pilots use
pilotage techniques that rely on nearby visual reference points and local knowledge of
tides, swells,
currents, depths and
shoals that might not be readily identifiable on
nautical charts without firsthand experience in certain waters. off the coast of Helsinki Legally, the master has full responsibility for the safe navigation of their vessel, even when a pilot is on board. If they have clear grounds that the pilot may jeopardize the safety of navigation, they can relieve the pilot from their duties and ask for another pilot, or, if not required to have a pilot on board, navigate the vessel without one. In every case, during the time passed aboard for operation, the pilot will remain under the master's authority, and always out of the "ship's command chain." The pilot remains aboard as an important and indispensable part of the bridge team. Only in transit of the
Panama Canal does the pilot have full responsibility for the navigation of the vessel. In some countries, deck officers of vessels who have strong local knowledge and experience of navigating in those ports, such as a
ferry or regular trader, may be issued with a pilotage exemption certificate, which relieves them of the need to take a pilot on board. == Remote pilotage ==
