The displacement of patrol ships and boats varies from several tons to 6,000 t, and the maximum speeds vary from 10 to 65 knots depending on the diversity of their missions and the specifics of operational areas.
Actually, patrol ships and boats are peacetime vessels designed to:
- guard the state border, exclusive economic zones and continental shelf;
- protect individual freighters and vessels loaded with hazardous cargoes in ports (harbors, roads), as well as underwater pipelines and communications cable lines;
- suppress smuggling, drug traffic and illegal migration;
- support customs, sanitary and other types of clearance of arriving and departing vessels;
- search for and rescue aircraft, helicopters, other flying vehicles, ships and vessels during accidents in coastal areas;
- maintain sea navigation aids;
- monitor ecological situation and reveal pollution sources.
In terms of missions and appropriate technical characteristics, patrol boats can be classified as:
- high-speed border guard boats designed to intercept trespassers;
- patrol boats intended to guard the exclusive economic zone and continental shelf from unauthorized activities (fishery, mining, etc.) of foreign vessels;
- coast guard boats well-equipped for search and rescue operations and used to monitor legally established navigation procedures in coastal areas and to help vessels and flying vehicles in emergency;
- police boats with a maximum displacement of 15 t intended to maintain order in port water areas and harbors, as well as to protect vessels loaded with hazardous cargoes;
- customs boats used to deliver teams of customs officers to and from arriving and departing vessels;
- special-purpose boats used to guard underwater pipelines and cables, monitor ecological situation in coastal areas and in airspace and to maintain navigation aids.
Considering high demand for patrol boats, the world's leading naval manufacturers pay much attention to this market segment. The analysis of world's naval fleets allows the identification of major exporters of patrol boats. The

The diagram shows that the
The long history of patrol ship operation and the rates of replenishment of naval inventories indicate that the patrol ship market is rather stable. This fact is confirmed by the diagram presented in Fig. 2. The forecasted growth of patrol boat purchases in 2000-2010 is attributable to the intensive development of coast guard and maritime police forces in some countries and patrol boats' expiring service lives.
The analysis of patrol boat imports in the total amount of acquisition is shown in Fig. 3 (acquisition before 2000, discarding after 2000). According to a retrospective analysis, on the average only half of commissioned ships was imported. The increase in the number of countries independently capable of building patrol boats with a maximum displacement of 600 t reduces the market by 10 to 15 percent and expands the opportunities of military-technical cooperation by establishing license production facilities.
