Obtaining the title "maritime pilot" requires being licensed or authorised by a recognised pilotage authority.
[2] 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.
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.
[13] 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.
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."
[16] 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.
[20] A 2008 review of pilot salaries in the United States showed that pay ranged from about US$250,000 to over US$500,000 per year.
[21] The Sandy Hook Pilots Association in Staten Island, New York, has 50 employees across its locations and generates $7.15 million in sales (USD).
