A patrol boat is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine, estuarine, or river environments.
The River class is a class of offshore patrol vessels built primarily for the Royal Navy of the United Kingdom. A total of nine were built for the Royal Navy (RN), four Batch 1 and five Batch 2. One Batch 1 (HMS Clyde), which was the Falklands guard ship, was decommissioned and transferred at the end of its lease to the Royal Bahrain Naval Force.
The SIGMA class is a Dutch-built family of modular naval vessels, of either corvette or frigate size, designed by Damen Group.
The Royal Australian Navy, although a significant force in the Asia-Pacific region, is nonetheless classed as a medium-sized navy. Its fleet is based around two main types of surface combatant, with limited global deployment and air power capability. However, in 2009, a white paper, Defending Australia in the Asia Pacific Century: Force 2030, was produced by the Australian government which set out a programme of defence spending that will see significant improvements to the RAN's fleet and capabilities.
The Damen Group is a Dutch defence, shipbuilding, and engineering conglomerate company based in Gorinchem, Netherlands.
HMS Severn is a River-class offshore patrol vessel of the Royal Navy. Named after the River Severn, the ship is the first to bear the name in 56 years. She was built by Vosper Thornycroft in Southampton, England, to serve primarily as a fishery protection unit within the United Kingdom's waters along with her two sister ships Mersey and Tyne. All three were commissioned into service in 2003 to replace the five older Island-class patrol vessels. The ship was decommissioned in 2017, but the Government decided to recommission her as part of Brexit preparedness. She returned to service in 2020 and was recommissioned into the Royal Navy on 28 August 2021.
Project Protector was a Royal New Zealand Navy (RNZN) procurement project that was undertaken during the 2000s. At the start of the decade, the New Zealand government tasked the New Zealand Defence Force to develop an equal combat, peacekeeping, and disaster relief capability, in which the RNZN was to focus on conducting sealift operations and patrols of the Economic Exclusion Zone. A series of reviews found that the RNZN was lacking in these capabilities, and Project Protector was established to acquire three new ship types: a single multi-role sealift ship, two offshore patrol vessels, and four inshore patrol vessels. After a two-year information-gathering and tender process, an Australian company, Tenix Defence, was selected as the primary contractor.
The Holland-class ocean-going patrol vessels are a class of four ocean-going patrol vessels constructed for the Royal Netherlands Navy. They are designed to fulfill patrol and intervention tasks against lightly armed opponents, such as pirates and smugglers, but have much higher level electronic and radar surveillance capabilities which are used for military stabilization and security roles, short of outright war. Without sonar or long range weapons, they utilize the surveillance capabilities of the Thales integrated mast, which integrates communication systems and two four-faced phased arrays for air and surface search.
DMS Maritime, formerly Defence Maritime Services, is a company providing port services to the Australian Defence Force and Marine Unit. It is a subsidiary of Serco.
The Arafura class is a class of offshore patrol vessels being built for the Royal Australian Navy (RAN). Initially proposed in the 2009 Defence White Paper and marked as procurement project SEA 1180, it was originally planned that 20 Offshore Combatant Vessels (OCV) would replace 26 vessels across four separate ship classes: the Armidale-class patrol boats, the Huon-class minehunters, the Leeuwin-class survey vessels, and the Paluma-class survey motor launches. Although having a common design, the ships would use a modular mission payload system to fulfill specific roles; primarily border patrol, mine warfare, and hydrographic survey. The 2013 Defence White Paper committed to the OCV project as a long-term goal, but opted in the short term for an accelerated procurement of an existing design to replace the Armidales, and life-extension refits for the other types. This resulted in the Offshore Patrol Vessel (OPV) project and the amount of vessels reduced to 12. However, this was further increased to 14 when 2 further Mine Counter Measures variants were proposed under SEA 1905.
Australian Defence Vessel (ADV) Ocean Protector is an auxiliary naval vessel of the Royal Australian Navy manned and managed by Teekay.
The Samarth-class offshore patrol vessel are a series of eleven offshore patrol vessels being built by Goa Shipyard Limited for the Indian Coast Guard.

They are an improvement over the earlier Sankalp class, with a larger beam and more powerful engines. The ships are being constructed in two batches—a batch of six ordered in May 2012 that was completed in December 2017 and a follow-on batch of five ordered in August 2016.

Sankalp-class offshore patrol vessels are a series of two offshore patrol vessels designed and built by Goa Shipyard Limited for the Indian Coast Guard. The vessels, also classified as Advanced Offshore Patrol Vessels, are the largest vessels constructed by Goa Shipyard Limited. Samarth class and Saryu class were derived from this class of offshore patrol vessels.
The Tun Fatimah class is an offshore patrol vessel (OPV) built by the Malaysian company THHE-Destini with the assistance of Damen company from the Netherlands based on the design of the Damen 1800-class OPV vessel.
