The Metal Shark 140 Defiant is based on the venerable Damen Stan Patrol 4207, which has been extensively proven with over 60 vessels either in service or under construction for multiple customers worldwide. The 140 Defiant was designed using the Damen “Enlarged Ship Concept” and offers superb operability and seakeeping characteristics coupled with outstanding fuel economy.

Advanced Hullform

The 140 Defiant is based on a globally-proven Damen hullform. The vessel 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 140 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. Most importantly, all Metal Shark-built Damen designs are supported by Damen’s global network of shipyards, so service is readily available worldwide. The 140 Defiant Offshore Patrol vessel is produced at Metal Shark’s large vessel shipyard complex in Franklin, Louisiana USA where upon completion it may be easily launched in the Gulf of Mexico.


The 140 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 140 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 140 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 140 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.
