A more economical alternative to its larger 85’ sibling, Metal Shark’s 80 Defiant is still highly capable. Based on Damen’s 2505 Stan Patrol design, the 80 Defiant offers key attributes of larger Defiant-class vessels including excellent performance and seakeeping, large payload capacity, economical operating cost, proven durability, and a modern crew-friendly design.

Hull Design & Construction

The 80 Defiant’s deep vee hull incorporates a raked bow, wide reversed chines, and spray rails to deliver a comfortable, dry ride. Integrated propeller tunnels enhance efficiency, reduce draft, and mitigate noise and vibration while underway. The stout welded aluminum hull features multiple watertight bulkheads and oversized scantlings throughout. A wide 19’ beam assures ample stability while underway or at rest. All integrated tanks and machinery areas have been designed for easy accessibility via watertight manholes or access hatches.

Deck Layout

Like its larger sibling, the 80 Defiant delivers ample payload capacity while allowing for safe and surefooted passage from bow to stern. Wide, non-skid walkways feature low-level LED lighting for night missions, and hand rails and grab handles are within easy reach at all times, allowing crew members to safely traverse the vessel, day or night, even in adverse weather conditions. Ample impact protection has been provided for docking or alongside maneuvers, and integrated stern ladders facilitate water access and recovery.

Payload Particulars

The 80 Defiant’s aft deck accommodates a 4.7-meter, 8-person Rigid Hulled Inflatable Boat (RHIB), which is deployed and retrieved via an integrated stern slipway. The vessel may serve as a fuel carrier, with 55-gallon drums securely stowed in ejection racks. The 80 Defiant’s versatility, combined with stability, endurance, and ample belowdecks crew accommodations, make the vessel ideal for extended patrol missions at sea.

Wheelhouse Details

The most immediately apparent advancement in Metal Shark’s Defiant pilothouse design is the use of pillarless glass to substantially enhance visibility. The result is a near elimination of the dangerous blind spots which are an unfortunate drawback of conventional pilothouse vessels. Large spotter windows allow the crew to see overhead aircraft. Further, the 80 Defiant’s quickly opening side and aft pilothouse windows offer added flexibility and greatly facilitate communication when docking or maneuvering alongside another vessel. The 80 Defiant is shown here with shock-mitigating seating for six. Other arrangements are available.

Metal Shark’s Franklin Shipyard

The 80 Defiant is produced at Metal Shark’s large vessel shipyard complex in Franklin, Louisiana. This 25-acre waterfront facility is situated with direct access to the Gulf of Mexico. Metal Shark’s Franklin yard supports aluminum and steel shipbuilding efforts for vessels up to 250’. Metal Shark is an experienced builder of custom patrol boats, with hundreds of vessels in service with the United States Coast Guard, Navy, Air Force, Army, the militaries of partner nations worldwide, and numerous port security and law enforcement agencies.
