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.
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.
The 55 Defiant’s spacious arrangement features wide-open work spaces that facilitate easy 360-degree crew movement around the boat.
