The Metal Shark 55 Defiant Fire Rescue is a next-generation welded aluminum monohull vessel designed for fire fighting, command and control, and other emergency response and security missions.The 55 Defiant employs Metal Shark’s Defiant-class hull design, which has been extensively tested and proven with hundreds of parent-class vessels in service worldwide. The 55 Defiant offers impressive capability, extended range and duration, large crew capacity, and easily carries a full complement of wholly integrated tactical fire fighting equipment. Like all Metal Sharks, each 55 Defiant Fire Rescue vessel is specially tailored to meet the specific needs of the customer.

Hull Design & Construction

The 55 Defiant features a proven Metal Shark hull design that has been engineered and built to precise tolerances. To achieve its superior hull life rating, the vessel’s hull, deck, and superstructure are composed entirely of heavy, welded plates of premium 5086 aluminum-magnesium alloy. The Defiant-class running surface has been designed for maximum efficiency and performance. This efficiency, combined with the vessel’s durable construction, results in the lowest possible operating cost while at the same time assuring maximum performance. Thanks to its wide beam, pronounced reverse chines, and ample heft, the 55 Defiant is exceptionally stable while underway, at rest, or pumping water. To meet specific mission requirements, the 55 Defiant may be equipped with inboards, water jets, or pod propulsion systems.

Deck Layout

The 55 Defiant’s spacious arrangement features wide-open work spaces that facilitate easy 360-degree crew movement around the boat. The large aft cockpit and available hydraulic crane can easily accommodate a deployable RIB, dive gear, and other rescue equipment or large payloads. Wide, non-skid walkways feature low-level LED lighting for night missions, and crew members will find hand rails and grab handles within easy reach at all times. Port and starboard dive recesses and a full-width transom platform provide easy access to and from the water. Heavy duty rub rail provides impact protection, and the vessel may be equipped with a urethane-sheathed closed-cell foam collar for additional fendering capability. Forward pusher knees are available to provide extra versatility



Metal Shark’s signature “pillarless” glass pilothouse sets the industry standard for visibility and safety. Proven extensively on Metal Shark’s military and law enforcement patrol boats and utilized on all Metal Shark pilothouse fireboats, this design drastically improves the view from the helm by reducing the dangerous blind spots commonly found on conventional pilothouse vessels. Firefighters and other emergency responders appreciate the near 360-degree view from a Metal Shark pilothouse, especially while on night missions or operating during other periods of reduced visibility.

Firefighters will find all controls for the vessel, fire fighting equipment, and other onboard systems within easy reach thanks to the 55 Defiant’s large port and starboard helm stations. These offer ample room for the installation of navigation electronics and controls for fire pumps and remote-operated fire monitors.

Crew Accommodations

The vessel shown here is equipped with basic helm seats, and port/starboard bench seats that convert to dual stretcher bunks in a water ambulance seating arrangement. Seating may be configured to suit. Metal Shark offers a wide range of options including shock mitigating military seating.

Down below, the 55 Defiant features a large convertible V-berth with dinette table, a galley, and an enclosed head compartment. A large mid-cabin area may be configured with additional bunks or used as a multi-use storage area.
