Based on the proven Damen Stan Patrol 5009 and built by Metal Shark in Louisiana USA, the 165 Defiant is an ocean-capable patrol vessel featuring Sea Axe technology that combines greatly enhanced efficiency with unsurpassed seakeeping abilities. The Stan Patrol design has been extensively proven, with multiple parent craft vessels in service with US and foreign militaries. Metal Shark, a leader in patrol boat design and construction, has applied its own proprietary patrol boat enhancements to this proven hullform. The result is a reliable and efficient vessel boasting next-generation features that enhance mission capability.

Advanced Hullform

Metal Shark’s 165 Defiant utilizes the Damen “Enlarged Ship Concept,” where the hull of a ship is extended to create an elongated hull form that substantially enhances seakeeping, operability and crew comfort by reducing vertical ship motions. The “Sea Axe” bow design represents a further evolution of the Enlarged Ship Concept. An Axe Bow vessel features an extremely slender and deep bow, without any flare, that provides unparalleled soft seakeeping characteristics, unrivaled operability, and increased fuel economy over conventional hull designs.


All Defiant offshore ships feature durable welded construction. The 165’ Defiant features a steel hull with aluminum deck and superstructure. Metal Shark’s expertise in patrol boat production, with hundreds of vessels in service worldwide, coupled with Damen’s technical expertise and global presence with shipyards worldwide, ensures a state of the art, precision craft that is built to last. The 165 Defiant is produced at Metal Shark’s large vessel shipyard complex in Franklin, Louisiana USA where upon completion vessels may be easily launched in the Gulf of Mexico.


The 165 Defiant features Metal Shark’s pillarless glass windshield, which significantly reduces blind spots. This, combined with the vessel’s elevated superstructure, provides ideal visibility for the crew. The 165 Defiant’s wheel house has been placed at the location where ship motions are least: approximately one third distance from the stern. This positioning creates the best possible working environment for the crew. The 165 Defiant been designed to allow for custom accommodations. A high-speed tender can be easily accommodated on the aft deck, where it can be launched from and recovered into an integrated stern slipway.

Crew Ergonomics

The 165 Defiant’s major controls and communication devices are integrated into the helmsman’s seat. Even in the most inclement conditions, the helmsman can easily and comfortably control the ship. Throughout the vessel, flexible carpentry and floating floors have been deployed to reduce vibration. Like all Metal Sharks, the interior layout may be fully customized to suit virtually any mission requirement.
