A maritime pilot, also known as a marine pilot, harbor pilot or bar pilot and sometimes simply called a pilot, is a sailor who maneuvers ships through dangerous or congested waters, such as harbors or river mouths. They are highly experienced shiphandlers possessing detailed knowledge of the particular waterway, e.g. actual depth, direction and strength of the wind, current and tide at any time of the day. The pilot is a navigational expert for the port of call.
Maneuvering a ship through the shallow water to berth / unberth in a port requires teamwork which involves, apart from the port pilot, the ship's captain (jointly responsible), ship's crew, port tugs, and shore linesmen. Since the pilot is on board the ship, they control the tugs and linesmen through a radio, and the ship directly. The ship's captain ensures their crew carry out the pilot's orders.
High skill is required to be a pilot as the channels through which the ships move towards the port are normally too narrow and shallow for the size of the ships, with the stopping distance of the ships being only a few nautical miles and the fact that ships do not steer at slow speed. Even if a ship captain is a regular visitor to a certain port, they can not match the expertise and experience of the Pilot.
In an unfortunate case of an accident, high pollution is a risk as a ship may carry thousands of tonnes of fuel for her own consumption.(Clean up cost and other damages of the Exxon Valdez disaster was around $5 billion). Also if a ship is wrecked in the channel, the channel and the port could be closed for months until the shipwreck is removed.
Most ports have compulsory pilotage.
Legally, the master has full responsibility for safe navigation of their vessel, even if 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 compulsory to have a pilot on board, navigate the vessel without one. Only in transit of the Panama Canal and in Canada does the pilot have the full responsibility for the navigation of the vessel.
In English law, Section 742 of the Merchant Shipping Act 1894 defines a pilot as "any person not belonging to a ship who has the conduct thereof." In other words, someone other than a member of the crew who has control over the speed, direction, and movement of the ship. The current United Kingdom legislation governing pilotage is the Pilotage Act 1987.
Pilotage is one of the oldest professions, as old as sea travel, and it is one of the most important in maritime safety. The oldest recorded history dates back to about the 7th century BC.  The economic and environmental risk from today's large cargo ships makes the role of the pilot essential[ citation needed].
The work functions of the pilot go back to Ancient Greece and Roman times, when locally experienced harbour captains, mainly local fishermen, were employed by incoming ships' captains to bring their trading vessels into port safely. Eventually, because the act of pilotage needed to be regulated and to ensure that pilots had adequate insurance, the harbours licensed pilots. The California Board of Pilot Commissioners was the first government agency created by California's legislature, in 1850.
Before harbour boards were established, pilots known as hobblers would compete with one another. The first to reach an incoming ship would navigate it to the docks and receive payment.  In Dún Laoghaire, Ireland, there is a monument to the hobblers who lost their lives.  In Kent they were known as "hovellers" and worked alongside and in competition with the licensed pilots, but were sometimes blamed as wreckers.  George Byng Gattie defends the hovellers or "hobilers" as lifesavers in his 1890 book about the Goodwin Sands. 
Although licensed by the harbour to operate within their jurisdiction, pilots were generally self-employed, and so had to have quick transport to get from the port to the incoming ships. As pilots were often still dual-employed, they used their own fishing boats to reach the incoming vessels. But fishing boats were heavy working boats, and filled with fishing equipment, hence a new type of boat was required.
Early boats were developed from single-masted cutters and twin-masted yawls, and later into the specialist pilot cutter. These were effectively light-weight and over-powered single masted boats with large steeply angled keels, making them deep draft under power and shallow draft in lighter sail. Joseph Henderson was an early American harbor pilot. He is well known for being a Sandy Hook Pilot for the New York harbor and along the Atlantic Coast during the Civil War.
Some historic pilot vessels are still sailing:
- Eighteen Bristol Channel Pilot Cutters are believed to survive worldwide. In addition to them...
- The German pilot schooner No. 5 Elbe was launched in 1883 and had a long history as pilot boat, as private yacht named Wander Bird and later as home to hippies in San Francisco, before returning to Germany and being restored as a traditional sailing boat.
- The German pilot schooner Cuxhaven was launched in 1901 and survived as a sailing boat, renamed Atalanta and still active as a traditional sail training ship under that name.
- The US motorboat USS California was completed in 1910 and served in World War I on harbor patrol duty.
- The US two-masted gaff-rigged schooner Adventuress launched in 1913 also saw service as a pilot boat, and during World War II served with the United States Coast Guard.
- The US two-masted gaff-rigged schooner Zodiac was built as a racing sailboat in 1924 and also named California after being acquired by the San Francisco Bar Pilots Association for use as a pilot boat.
- The US schooner Roseway, built in 1925, owned by the Boston Pilot Association for thirty years until 1973, now a registered U.S. National Historic Landmark operating in Boston and St. Croix, USVI by World Ocean School, Camden, ME.
In the Inland Brown Water Trade another type of pilots are 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.[ citation needed]
Their size and mass makes large ships very difficult to manoeuvre; the stopping distance of a supertanker is typically measured in miles/kilometers and even a slight error in judgment can cause millions of dollars in damage. For this reason, many years of experience in an operating area are required to qualify as a pilot.[ citation needed] For example, the California Board of Pilot Commissioners requires that pilot trainees must 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 all types of vessel and docking facilities. Following licensing, pilots are required to engage in extensive continuing educational programs. 
By far the most challenging part of any ship's voyage is the passage through the narrow waterways that lead to port and the final docking of the ship. The pilot brings to the ship expertise in handling large vessels in confined waterways and expert local knowledge of the port. In addition to bringing local maritime expertise on board, unlike the vessel's captain the pilot is insulated from the economic pressures (e.g., getting the ship from point A to point B on time, regardless of weather conditions, traffic, or other navigation issues) that can compromise safety. Instead of being part of the ship's crew, pilots are employed locally and therefore act on behalf of the public rather than of the shipowners.[ citation needed]
Normally, 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 40 feet (~12 metres) to the deck of the largest container and tanker ships. Climbing the pilot ladder can be dangerous, even more so in rough seas considering that both the ship to be piloted and the pilot's own vessel are usually both moving. With outgoing vessels, a pilot boat returns the pilot to land after the ship has successfully negotiated coastal waters.[ citation needed] 
Pilots specifically use pilotage techniques relying 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 first hand experience in the waters in question.[ citation needed]
Beyond the experience and training of regular ships' captains, pilots also receive special, ongoing training to stay on top of their profession. Pilots are required by law in most major sea ports of the world for large ships.[ citation needed]. In every case, during the time passed aboard for operation, the pilot will remain under the Master's authority, and always out of "ship's command chain". The pilot remains aboard as an important and indispensable -Consultant of the Master-.
However, in some countries, Masters (and sometimes other ranks too) of ships that call at only a few ports and so have strong local knowledge and experience of navigating in those ports, such as a ferry, may be issued with a pilotage exemption certificate, which relieves them of the need to take a pilot on board.

Because maritime pilots have advanced to the top of the maritime profession and are responsible for the most dangerous part of a voyage, they are generally well compensated.[ citation needed]
The Florida Alliance of Maritime Organizations reported that Florida pilots salaries range from US$100,000 to US$400,000 annually. This was similar to other US states with large ports.  Columbia River bar pilots earn about US$180,000 per year.  A 2008 review of pilot salary in the United States showed that pay ranged from about US$250,000 to over US$500,000 per year. 
Pilot compensation has been controversial in many ports, including Los Angeles and Long Beach, California, especially regarding pilots who are employed by public agencies instead of acting as independent contractors.  
Compensation varies in other nations. In New Zealand, according to the government career service, pilots earn NZ$90,000-120,000.
