This “Heavy Duty” custom designed and built Fireboat for the City of Chicago is one example of the type of Fireboats offered. In this case the vessel is designed to break up to 12 inches of first year ice at a speed of 3 knots. This enables the vessel to operate “year round”. Although primarily a firefighting vessel, the vessel is also used for “multi-tasks”, such as diving support, search and rescue, distress response for recreational boaters, and a station pumping to supplement the Cities fire-main supply of water in the event of a major fire inland. The Fireboat normally operates with a crew of 5 but increases to 10 when firefighting. The vessel has a full galley, washrooms, medical treatment room, crew accommodations and Haz-Mat showers.
