A patrol boat (also referred to as a patrol craft, patrol ship or patrol vessel) is a relatively small naval vessel generally designed for coastal defence duties. There have been many designs for patrol boats. They may be operated by a nation's navy, coast guard, police force or customs and may be intended for marine (blue water) or estuarine or river ("brown water") environments. They are commonly found engaged in various border protection roles, including anti-smuggling, anti-piracy, fisheries patrols, and immigration law enforcement. They are also often called upon to participate in rescue operations. Vessels of this type include the original yacht (from Dutch/Low German jacht meaning hunting or hunt), a light, fast-sailing vessel used by the Dutch navy to pursue pirates and other transgressors around and into shallow waters.
They may be broadly classified as inshore patrol vessels (IPVs) and offshore patrol vessels (OPVs). They are warships typically smaller in size than a corvette and can include fast attack craft, torpedo boats and missile boats, although some are as large as a frigate. The offshore patrol vessels are usually the smallest ship in a navy's fleet that is large and seaworthy enough to patrol off-shore in the open ocean. In larger militaries, such as in the United States military, offshore patrol vessels usually serve in the coast guard, but many smaller nations navies operate these type of ships.
During both World Wars in order to rapidly build up numbers, all sides created auxiliary patrol boats by arming motorboats and seagoing fishing trawlers with machine guns and obsolescent naval weapons. Some modern patrol vessels are still based on fishing and leisure boats. Seagoing patrol boats are typically around 30 m (100 ft) in length and usually carry a single medium caliber artillery gun as main armament, and a variety of lighter secondary armament such as machine guns or a close-in weapon system. Depending on role, vessels in this class may also have more sophisticated sensors and fire control systems that would enable them to carry torpedoes, anti-ship and surface-to-air missiles.
Most modern designs are powered by gas turbine arrangements such as CODAG, and speeds are generally in the 25–30 knots (46–56 km/h; 29–35 mph) range. They are primarily used for patrol in a country's Exclusive Economic Zone. Common tasks are fisheries inspection, anti-smuggling (usually anti-narcotics) duties, illegal immigration patrols, anti-piracy patrols and search and rescue (law enforcement-type of work). The largest OPVs might also have a flight deck and helicopter embarked. In times of crisis or war, these vessels are expected to support the larger vessels in the navy.
Their small size and relatively low cost make them one of the most common type of warship in the world. Almost all navies operate at least a few offshore patrol vessels, especially those with only "green water" capabilities. They are useful in smaller seas such as the North Sea as well as in open oceans. Similar vessels for exclusively military duties include torpedo boats and missile boats. The United States Navy operated the Pegasus class of armed hydrofoils for years, in a patrol boat role. The River Patrol Boat (PBR, sometimes called "Riverine" and "Pibber") is a U.S. design of small patrol boat type designed to patrol waters of large rivers.

HMAS Advance (P 83) was an Attack-class patrol boat of the Royal Australian Navy (RAN). Constructed during 1967 and commissioned into the RAN in 1968, Advance operated from Darwin and patrolled northern Australian waters.
During her career, the patrol boat shadowed a Soviet trawler, survived Cyclone Tracy, was used for filming of the television series Patrol Boat, and participated in the RAN's first anti-terrorism patrol of the North West Shelf. Advance was replaced in 1980, but continued to operate as a training ship until she was decommissioned in 1988.
Advance was donated to the Australian National Maritime Museum, which has maintained her in an operational condition.HMAS Bombard (P 99)
HMAS Bombard (P 99) was an Attack class patrol boat of the Royal Australian Navy (RAN).Insect-class gunboat
The Insect-class gunboats (or large China gunboats) were a class of small, but well-armed Royal Navy ships designed for use in shallow rivers or inshore. They were intended for use on the Danube against Austria-Hungary (the China name was to disguise their function). The first four ships—Gnat, Mantis, Moth and Tarantula—were first employed during the World War I Mesopotamian Campaign on the Euphrates and Tigris rivers.Island-class patrol boat
The Island-class patrol boat is a class of cutters of the United States Coast Guard. 49 cutters of the class were built, of which 37 remain in commission. Their hull numbers are WPB-1301 through WPB-1349.List of United States Coast Guard cutters

Boltenhagen (GS09) was a Kondor I-class minesweeper built in East Germany. After the Volksmarine was disbanded just before the reunification of Germany, she was sold to Malta in 1997 and renamed P29 and was used as a patrol boat. After being decommissioned, she was scuttled as a dive site in 2007 off Ċirkewwa.Maltese patrol boat P31
Pasewalk (GS05) was a Kondor I-class minesweeper built in East Germany. After the Volksmarine was disbanded just before the reunification of Germany, she was sold to Malta in 1992 and renamed P31 and was used as a patrol boat. After being decommissioned, she was scuttled as a dive site in 2009 off Comino.Marine Protector-class patrol boat
The Marine Protector class is a class of coastal patrol boats of the United States Coast Guard.
The 87-foot-long vessels are based on the Stan 2600 design by Damen Group, and were built by Bollinger Shipyards of Lockport, Louisiana. Each boat is named after a marine predator.The Coast Guard placed its original order in 1999 for 50 boats, which were delivered by mid-2002.
Several additional orders brought the class to a total of 74 ships, with the last, USCGC Sea Fox, being completed in October 2009.
Four additional vessels were built for Foreign Military Sales, with two each going to Malta and Yemen.The Marine Protector class replaced the 82-foot Point class. These older boats had one small and one large berthing area, and they had to stop for five or more minutes to deploy or retrieve their pursuit inflatable boat via a small crane. The last Point-class cutter was decommissioned in 2003.Patrol Boat, River
Patrol Boat, Riverine or PBR, is the United States Navy designation for a small rigid-hulled patrol boat used in the Vietnam War from March 1966 until the end of 1971. They were deployed in a force that grew to 250 boats, the most common craft in the River Patrol Force, Task Force 116, and were used to stop and search river traffic in areas such as the Mekong Delta, the Rung Sat Special Zone, the Saigon River and in I Corps, in the area assigned to Task Force Clearwater, in an attempt to disrupt weapons shipments. In this role they frequently became involved in firefights with enemy soldiers on boats and on the shore, were used to insert and extract Navy SEAL teams, and were employed by the United States Army's 458th Transportation Company, known as the 458th Sea Tigers. The PBR was replaced by the Special Operations Craft – Riverine (SOC-R)Stenka-class patrol boat
The Stenka class is the NATO reporting name for a class of patrol boats built for the Soviet Navy and Soviet Allies. The Soviet designation was Project 205P Tarantul (not to be confused with the Tarantul-class corvette). The boats are an anti-submarine (ASW) patrol boat version of the Osa-class missile boat.Super Dvora Mk II-class patrol boat
The Super Dvora Mark II-class patrol boats is a high-speed class of patrol boats meant for a variety of naval missions from typical off-shore coastal patrol mission profiles to high-speed, high-maneuver littoral warfare. Built by Israel Aerospace Industries for the Israeli Sea Corps, the Super Dvora Mark II is the successor to the Dvora-class fast patrol boats. The Super Dvora Mark IIs have been employed by the Sri Lanka Navy to counter LTTE operations at sea.Svetlyak-class patrol boat
Svetljak-class patrol boats (NATO name "Svetlyak") are patrol boats designed and built in Russia, and mostly used by the Russian Navy in various missions.USCGC Citrus (WLB-300)
USCGC Citrus (WAGL-300/WLB-300/WMEC-300) was a Cactus (A)-class seagoing buoy tender built in 1942 in Duluth, Minnesota, and now operated by the navy of the Dominican Republic.
During World War II, the 180-foot ship helped build LORAN stations on the Aleutian Islands. From 1945 to 1979, Citrus largely helped maintain aids to navigation in Alaskan waters. In 1980, she was converted into a medium-endurance cutter homeported at Coos Bay, Oregon.
In 1995, after 51 years' service, it was transferred to the Dominican Navy, which commissioned it Almirante Juan Alejandro Acosta.USCGC Point Hannon (WPB-82355)
USCGC Point Hannon (WPB-82355) was an 82-foot (25 m) Point class cutter constructed in 1967 for use as a law enforcement and search and rescue patrol boat.USS Genesee (AT-55)
USS Genesee (AT-55), formerly Monocacy, was a fleet tug in the U.S. Navy in World War I and World War II built in 1905. She was scuttled on 5 May 1942 at Corregidor to avoid capture. Nevertheless, she was raised by the Japanese and designated as Patrol Boat No. 107. She was sunk by American planes on 5 November 1944.USS Stewart (DD-224)
USS Stewart (DD-224) was a Clemson-class destroyer in the United States Navy during World War II. She was the second ship named for Rear Admiral Charles Stewart. Scuttled in a port, she was later raised by the Japanese and commissioned as Patrol Boat No. 102. She came back under American control in 1945 after the occupation of Japan.VMV-class patrol boat
VMV-class patrol boat (Finnish: Vartiomoottorivene) was a series of Finnish patrol boats, which served with the Finnish Coast Guard and the Finnish Navy during World War II.Zhuk-class patrol boat
The Zhuk-class patrol boat, also known as Project 1400M "Grif", is a small border patrol vessel of less than 40 ton displacement built in the Soviet Union and later in Autonomous Republic of Crimea, Ukraine. Over 300 boats were built between 1969 and 1991. Out of those, 110 were sold to 23 other countries.
Exact numbers are unknown, but they were widely exported by the Soviet Union in addition to use in home waters as harbor patrol. The vessels were excellent for this task thanks to a cheap design for mass production. With only a single simple radar unit and manually-aimed machine guns, they made ideal patrol boats. The dissolution of the Soviet Union in 1991, and the abolition of its primary user the, KGB Maritime Guard, it was taken over by the Russian Federal Coast Guard. By 2007 only 15-20 remained in service with the Russian Navy.
