# Water police

Water police, also called bay constables, coastal police, harbor patrols, marine/maritime police/patrol, nautical patrols, port police, or river police are a specialty law enforcement portion of a larger police organization, who patrol in water craft. Their patrol areas may include coastal tidal waters, rivers, estuaries, harbors, lakes, canals or a combination of these.

## Duties and functions

Water police are usually responsible for ensuring the safety of water users, enforcing laws relating to water traffic, preventing crime on vessels, banks and shores, providing search and rescue services (either as the main provider or as an initial response unit before more specialized units arrive), and allowing land-based police to reach locations not easily accessible. They may also be responsible for coastal security, environmental law enforcement, immigration and smuggling interdiction, and diving operations (although many police organizations have separate units to handle this). Their operations may coordinate with other agencies with similar assets such as in the United States the various Federal, State or Local authorities may work together to promote or achieve similar enforcement or rescue outcomes. In the United States, some states have combined the duties of water police with those of conservation officers or state police.
Equipment used ranges from personal water craft and inflatable boats to large seagoing craft, but most police vessels are small to medium, fast motorboats. In some areas these vessels incorporate a firefighting capability through a fixed deck nozzle. The operators of these vessels are generally trained in many rescue disciplines including first aid, vessel dewatering, and firefighting. They may also be trained as divers for rescue and recovery and as boat operators who may engage in towing operations.
