Montreux Convention (1936) ..
Flag of convenience (FOC) is a business practice whereby a ship's owners
register a
merchant ship in a ship register of a country other than that of the ship's owners, and the ship flies the
civil ensign of that country, called the
flag state. The term is often used pejoratively, and although common, the practice is sometimes regarded as contentious. Each merchant ship is required by
international law to be registered in a registry created by a country, and a ship is subject to the laws of that country, which are used also if the ship is involved in a case under
admiralty law. A ship's owners may elect to register a ship in a foreign country which enables it to avoid the regulations of the owners' country which may, for example, have stricter safety standards. They may also select a jurisdiction to reduce operating costs, avoiding higher taxes in the owners' country and bypassing laws that protect the wages and working conditions of
mariners. The term "flag of convenience" has been used since the 1950s. A registry which does not have a
nationality or
residency requirement for ship registration is often described as an open registry. Panama, for example, offers the advantages of easier registration (often online) and the ability to employ cheaper foreign labour. Furthermore, the foreign owners pay no income taxes.
The modern practice of ships being registered in a foreign country began in the
1920s in the
United States when shipowners seeking to serve alcohol to passengers during
Prohibition registered their ships in Panama. Owners soon began to perceive advantages in terms of avoiding increased regulations and rising labor costs and continued to register their ships in
Panama even after Prohibition ended. The use of open registries steadily increased, and in 1968,
Liberia grew to surpass the
United Kingdom with the world's largest ship register. As of 2009,
more than half of the world's merchant ships were registered with open registries, and almost 40% of the entire world fleet, in terms of
deadweight tonnage, were registered in
Panama, Liberia, and the Marshall Islands. In 2006, up to 20% of high-seas fishing vessels were registered in states they were not connected to. According to
IHS Markit, in March 2017, Panama had 8,052 ships on its registry,
Singapore had 3,574 ships, Liberia had 3,277 ships, the Marshall Islands had 3,244 ships and
Hong Kong had 2,594 ships.
Open registries have been criticised, mainly by
trade union organisations based in developed countries, especially those in the European Union, United States, Japan, Canada, or the United Kingdom. One criticism is that shipowners who want to hide their ownership may select a flag-of-convenience jurisdiction which enables them to be legally anonymous. Some ships with flags of convenience have been found engaging in crime, offering substandard working conditions, and negatively impacting the environment, primarily through
illegal, unreported and unregulated fishing. Prior to the implentation of the
International Convention on Tonnage Measurement of Ships, 1969, shipowners may have selected a jurisdiction with measurement rules that reduced the certified
gross register tonnage of a ship, to reduce subsequent port of call dock dues. Such was a consideration when
Carnival Cruise Line changed the flag of the RMS
Empress of Canada in 1972 to that of Panama.[

Cunard Line registered all its ships in
Bermuda, which, besides other considerations, enabled its ship captains to marry couples at sea. Weddings at sea are described as a lucrative market.
As of 2009, thirteen flag states have been found by
international shipping organisations to have substandard regulations. On the other hand, maritime industry practitioners and seafarers from other countries contend that this is a natural product of globalisation. Supporters of the practice, however, point to economic and regulatory advantages, and increased freedom in choosing employees from an international labour pool. Ship owners from developed countries use the practice to be competitive in a global environment. As of 2009, ships of thirteen flags of convenience have been targeted for special enforcement by countries when they visit ports in those countries, called
port state control.
The
United Nations Convention on the Law of the Sea (
UNCLOS), also called the
Law of the Sea Convention or
the Law of the Sea treaty, is an international agreement that resulted from the third United Nations Conference on the Law of the Sea (UNCLOS III), which took place
between 1973 and 1982. The Law of the Sea Convention defines the rights and responsibilities of nations with respect to their use of the world's oceans, establishing guidelines for businesses, the environment, and the management of marine
natural resources. The Convention, concluded in
1982, replaced the
quad-treaty 1958 Convention on the High Seas. UNCLOS came into force in
1994, a year after
Guyana became the
60th nation to ratify the treaty. As of
June 2016, 167 countries and the
European Union have joined in the Convention. It is
uncertain as to what extent the Convention
codifies customary international law.
UNCLOS replaces the
older 'freedom of the seas' concept, dating from the
17th century. According to this concept, national rights were limited to a specified belt of water extending from a nation's
coastlines, usually
3 nautical miles (5.6 km; 3.5 mi) (
three-mile limit), according to the '
cannon shot' rule developed by the Dutch jurist
Cornelius van Bynkershoek. All waters beyond national boundaries were considered
international waters: free to all nations, but belonging to none of them (the
mare liberum principle promulgated by
Hugo Grotius).
In the
early 20th century, some nations expressed their desire to extend national claims: to include
mineral resources, to
protect fish stocks, and to provide the means to
enforce pollution controls. (The
League of Nations called a
1930 conference at
The Hague, but no agreements resulted.) Using the customary international law principle of a nation's right to protect its natural resources, President
Harry S. Truman in
1945 extended United States control to all the natural resources of its
continental shelf. Other nations were quick to follow suit. Between
1946 and 1950,
Chile, Peru, and Ecuador extended their rights to a distance of
200 nautical miles (370 km; 230 mi) to cover their
Humboldt Current fishing grounds. Other nations extended their territorial seas to
12 nautical miles (22 km; 14 mi).
[7]By
1967,
only 25 nations still used the
old three nautical mile limit, while
66 nations had set a
12-nautical-mile (22 km) territorial limit and
eight had set a
200-nautical-mile (370 km) limit. As of
28 May 2008, only
two countries (Jordan and Palau) still use the
3-mile (4.8 km) limit. That limit is also used in certain
Australian islands, an area of
Belize, some
Japanese straits, certain areas of
Papua New Guinea, and a few
British Overseas Territories, such as
Gibraltar.
