A fireboat is a specialized watercraft with pumps and nozzles designed for fighting shoreline and shipboard fires. The first fireboats, dating to the late 18th century, were tugboats, retrofitted with firefighting equipment. Older designs derived from tugboats and modern fireboats more closely resembling seafaring ships can both be found in service today. Some departments would give their multi-purpose craft the title of "fireboat" also.
They are frequently used for fighting fires on docks and shore side warehouses as they can directly attack fires in the supporting underpinnings of these structures. They also have an effectively unlimited supply of water available, pumping directly from below the hull. Fireboats can be used to assist shore-based firefighters when other water is in low supply or is unavailable, for example, due to earthquake breakage of water mains, as happened in San Francisco due to the 1989 Loma Prieta earthquake.
Some modern fireboats are capable of pumping tens of thousands of gallons of water per minute. An example is Fire Boat #2 of the Los Angeles Fire Department, the Warner Lawrence, with the capability to pump up to 38,000 US gallons per minute (2.4 m3/s; 32,000 imp gal/min) and up to 400 feet (122 m) in the air.
Fireboats are most usually seen by the public when welcoming a fleet or historical ships with a display of their water moving capabilities, throwing large arcs of water in every direction.
Occasionally fireboats are used to carry firefighters, Emergency Medical Technicians, and a physician with their equipment to islands and other boats. Some may be used as icebreakers, like the Chicago Fire Department's Victor L. Schlaeger which can break 8 to 12 inch ice. They may also carry divers or surface water rescue workers. Passengers from ships in danger can be also transferred to various kind of rescue boats. Rescue boats may be used also for oil and chemical destruction on rivers, lakes and seas.For example, the Helsinki Rescue Department in Helsinki, Finland has various kinds of boats for various kind of firefighting, rescue, and oil destruction tasks.
Also hydrocopters, rigid-hulled inflatable boats, fanboat and even hovercrafts and helicopters are used in fire, rescue and medical emergency situations.
Cities with fireboats are usually located on a large body of water with port facilities. Smaller fire departments lacking resources will use rigid-hulled inflatable boat or borrow boats from local rescue agencies (EMS, coast guard, military).[en]
