A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade
licensed mariner who holds ultimate command and responsibility of a merchant vessel.
[Aragon and Messner, 2001, p.3.] The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board.
Duties and functions
The captain ensures that the ship complies with local and international laws and complies also with company and
flag state policies.
The captain is ultimately responsible, under the law, for aspects of operation such as the safe navigation of the ship,
[Aragon and Messner, 2001, p.4.] its cleanliness and seaworthiness,
[Aragon and Messner, 2001, p.5.] safe handling of all cargo,
[Aragon and Messner, 2001, p.7.] management of all personnel,
[Aragon and Messner, 2001, p.7-11.] inventory of ship's cash and stores,
[Aragon and Messner, 2001, p.11-12.] and maintaining the ship's certificates and documentation.
[Aragon and Messner, 2001, p.13-15.]
One of a shipmaster's particularly important duties is to ensure compliance with the vessel's security plan, as required by the

and responding to threats from terrorists, hijackers, pirates, and stowaways.
[Aragon and Messner, 2001, p.103-111.] The security plan also covers topics such as

asylum seekers, smuggling, and saboteurs.

[Aragon and Messner, 2001, p.211-223.] and managing the ship's
slop chest.

[Aragon and Messner, 2001, p.175-208.] Immigration issues can include situations such as embarking and disembarking passengers,
[Aragon and Messner, 2001, p.208.] handling crew members who desert the ship,
[Aragon and Messner, 2001, p.206-207.] making crew changes in port,
[Aragon and Messner, 2001, p.207.] and making accommodations for foreign crew members.
[Aragon and Messner, 2001, p.204, 206, 208.] Customs requirements can include the master providing a cargo declaration, a ship's stores declaration, a declaration of crew members' personal effects, crew lists and passenger lists.
[Aragon and Messner, 2001, p.183-187.]
The captain has special responsibilities when the ship or its cargo are damaged, when the ship causes damage to other vessels or facilities. The master acts as a liaison to local investigators
[Aragon and Messner, 2001, p.46-47.] and is responsible for providing complete and accurate logbooks, reports, statements and evidence to document an incident.
[Aragon and Messner, 2001, p.47-49.] Specific examples of the ship causing external damage include collisions with other ships or with fixed objects, grounding the vessel, and dragging anchor.
[Aragon and Messner, 2001, p.52-61.] Some common causes of cargo damage include heavy weather, water damage, pilferage, and damage caused during loading/unloading by the
stevedores.
[Aragon and Messner, 2001, p.65-69.]
All persons on board including public authorities, crew, and passengers are under the captain's authority and are his or her ultimate responsibility, particularly during navigation. In the case of injury or death of a crew member or passenger, the master is responsible to address any medical issues affecting the passengers and crew by providing medical care as possible, cooperating with onshore medical personnel, and, if necessary, evacuating those who need more assistance than can be provided on board the ship.
[Aragon and Messner, 2001, p.77-89.]
Performing marriages
There is a common belief that ship captains have historically been, and currently are, able to perform marriages. This depends on the country of registry, however most do not permit performance of a marriage by the master of a ship at sea.
In the
United States Navy, a captain's powers are defined by its 1913 Code of Regulations, specifically stating: "The commanding officer shall not perform a marriage ceremony on board his ship or aircraft. He shall not permit a marriage ceremony to be performed on board when the ship or aircraft is outside the territory of the United States." However, there may be exceptions "in accordance with local laws and the laws of the state, territory, or district in which the parties are domiciled" and "in the presence of a diplomatic or consular official of the United States, who has consented to issue the certificates and make the returns required by the consular regulations."
Furthermore, in the
United States, there have been a few contradictory legal precedents: courts did not recognize a shipboard marriage in
California's 1898 ''Norman v. Norman'' but did in
New York
New York most commonly refers to:
* New York City, the most populous city in the United States, located in the state of New York
* New York (state), a state in the northeastern United States
New York may also refer to:

* '' ...
's 1929 ''Fisher v. Fisher'' (notwithstanding the absence of municipal laws so carried) and in 1933's ''Johnson v. Baker'', an
Oregon court ordered the payment of death benefits to a widow because she had established that her marriage at sea was lawful. However, in ''Fisher v. Fisher'' the involvement of the ship's captain was irrelevant to the outcome.
New Jersey's 1919 ''Bolmer v. Edsall'' said a shipboard marriage ceremony is governed by the laws of the nation where ownership of the vessel lies.
In the
United Kingdom, the captain of a merchant ship has never been permitted to perform marriages, although from 1854 any which took place had to be reported in the ship's log. A ship's master can, however, conduct a church service, regardless of any clergy aboard.
Spanish and
Filipino law, as narrow exceptions, recognise a marriage ''in articulo mortis'' (on the point of death) solemnized by the captain of a ship or chief of an aeroplane during a voyage, or by the commanding officer of a military unit.

Southampton to Bermuda in 2011 to allow marriages to be conducted on their ships.
Some captains obtain other credentials (such as ordination as ministers of religion or accreditation as notaries public), which allow them to perform marriages in some jurisdictions where they would otherwise not be permitted to do so.
Another possibility is a wedding on a ship in port, under the authority of an official from that port.
In works of fiction, ship captains have performed marriages in various media, including the 1951 film ''
The African Queen'', and episodes of ''
The Love Boat'', ''

Uniform

Uniforms are worn aboard many ships, or aboard any vessels of traditional and organized navigation companies, and are required by company regulation on passenger and cruise vessels.
In the passenger-carrying trade a unified corporate image is often desired and it is useful for those unfamiliar with the vessel to be able to identify members of the crew and their function. Some companies and some countries use an
executive curl similar to that of the
Royal Navy.
In the United States, and in numerous other maritime countries, captains and officers of shipping companies may wear a
merchant navy or
merchant marine regular uniform in conjunction with their employment.

ship." At sea, or upon lakes and rivers, the skipper as shipmaster or captain has command over the whole crew. The skipper may or may not be the owner of the boat.
The word is derived from the
Dutch word ''schipper''; ''schip'' is Dutch for "ship". In Dutch ''sch-'' is pronounced and English-speakers rendered this as .
The word "skipper" is used more than "captain" for some types of craft, for example
fishing boats.
It is also more frequently used than captain with privately owned noncommercial or semi-commercial vessels, such as small
yachts and other recreational boats, mostly in cases where the person in command of the boat may not be a licensed or professional captain, suggesting the term is less formal. In the U.S., a "skipper" who is in command of a charter vessel that carries paying passengers must be licensed by a state or the USCG. If the vessel carries over six paying passengers, it must be an "inspected vessel" and a higher class license must be obtained by the skipper/master depending on the vessel's gross tons.
