Maritime pilot

A maritime pilot, marine pilot, harbor pilot, port pilot, ship pilot, or simply pilot, is a mariner who has specific knowledge of an often dangerous or congested waterway, such as harbors or river mouths. Maritime pilots know local details such as depth, currents, and hazards. They board and temporarily join the crew to safely guide the ship's passage, so they must also have expertise in handling ships of all types and sizes. Obtaining the title "maritime pilot" requires being licensed or authorised by a recognised pilotage authority.

The word pilot is believed to have come from the Middle French, pilot, pillot, from Italian, pilota, from Late Latin, pillottus; ultimately from Ancient Greek πηδόν (pēdón, "blade of an oar, oar").

The work functions of the pilot can be traced back to Ancient Greece and Rome, when locally experienced harbour captains, mainly local fishermen, were employed by incoming ships' captains to bring their trading vessels into port safely.

The pilot boat was made to quickly reach incoming ships from port. Harbor masters began to require licensing and insured pilots and placed regulations on incoming ships to bring pilots aboard.

Inland brown water trade also relies on the work of pilots known as trip pilots. Due to the shortage of qualified posted masters, these independent contractors fill the holes in the manning schedule on inland push boats on various inland river routes.

A Sandy Hook pilot is a licensed maritime pilot for the Port of New York and New Jersey, the Hudson River, and Long Island Sound. Sandy Hook pilots have been piloting ships in the New York Harbor for over 300 years. The pilots of New York and Boston first served on Square rigs before entering the pilot service as boat keepers, later receiving their warrants as pilots, then their full commissions as branch pilots authorized to pilot vessels of any draught size.

In 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.
