Metal Shark’s versatile 29 Defiant combines groundbreaking, crew-friendly features with a nimble and robust hull. Hundreds of 29 Defiant patrol boats are currently in service with the US Coast Guard, with new boats delivering weekly to USCG stations across the US. In addition, the 29 Defiant continues to gain popularity among state, local, and municipal law enforcement agencies due to it’s highly versatile and practical layout, its handling and ride, and its durability. A truly global platform, 29 Defiant patrol boats are also in service with over a dozen foreign militaries across Latin America and the Caribbean, Africa, Asia, and the Middle East.

Hull Design

The 29 Defiant features all-aluminum construction, with its precision-welded hull, deck, and pilothouse composed entirely of premium-grade 5086 aluminum alloy. An 8’6” beam makes the 29 Defiant ideal for over-the-road transport, however, thanks to wide reversed chines and the ample heft of its stout hull, the vessel is stable while underway or at rest. Twin outboard engines require minimum maintenance while reliably propelling the vessel to speeds up to 50 knots. The 29 Defiant is also available with diesel inboards with water jets. A twin stern drive configuration is also available. In any configuration, the 29 Defiant delivers quick acceleration, nimble handling, and a soft smooth ride.

Deck Layout

The 29 Defiant boasts a clutter-free deck arrangement that allows for easy, surefooted passage from bow to stern, with wide-open workspaces and non-skid walkways throughout. Low-level LED pathway illumination has been provided for night missions, and grab rails are ideally placed and always within easy reach. The 29 Defiant is offered with various configurations to suit operator needs. The vessel may be equipped with an open-bow configuration with the bow cockpit easily accessed through a large sliding companionway door in the pilothouse. A closed-bow version with v-berth is also available (both versions shown).


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 that are an unfortunate drawback of conventional pilothouse vessels. Further, the 29 Defiant’s quickly opening side and aft pilothouse doors offer added flexibility and greatly facilitate communication when docking or maneuvering alongside another vessel. Multiple seat options and seating arrangements are available, including shock-mitigating military seats, to meet the needs and requirements of specific customers.

Convertible Window System

Metal Shark developed a unique window system for the USCG that allows the side and aft windows to quickly drop into the hull, converting the vessel from a full cabin to an open boat. No longer must a choice be made between the utility of an open boat and the all-weather capability of a pilothouse; the Metal Shark Defiant deftly combines the best of both. The convertible window system is available on all standard-cabin 29 Defiants.

Short-Cabin Configuration

The 29 Defiant is available in a short cabin configuration, which offers increased aft cockpit space. This layout is popular among law enforcement agencies and emergency responders who require more working room outside the pilothouse. There is space within the shortened cabin for four, instead of the maximum six-person seating layout available with the standard cabin.


With a deep vee hull and power options up to 600 HP, the 29 Defiant will slice through the waves, and its wide reverse chines provide stability while at rest. Available with a wide range of power options and propulsion types, the 29 Defiant is responsive and maneuverable. Thanks to its 8’6” beam, the 29 Defiant is legal for over the road transport. Its radar mast quickly folds down into the aft cockpit to achieve trailerable clearance. Powered by twin outboard engines, the 29 Defiant reaches speeds in excess of 50 knots.

Twin Diesel Waterjet Configuration

The 29 Defiants shown here were built for a foreign military and equipped with twin Yanmar 6LPA-STP2 diesels mated to Hamilton 241 jet drives. This package delivers the reliability and economy of inboard diesels, plus the shallow-draft capability and maneuverability of water jet propulsion. By utilizing the water jet’s split-duct thrust-reversing “buckets,” the vessel can be brought from planing speed to a full stop within two boat lengths. Pivoting, turning, crabbing sideways, and other maneuvers are accomplished with ease. Top speed as equipped exceeds 40 knots. Also shown here are the available tubular swim platform, aft guard rails, and tow rope line spool.

Twin Diesel Stern Drive Configuration

The 29 Defiant shown here, built for the New York City Department of Environmental Protection, is a short-cabin version powered by twin Volvo D4-225 diesels and stern drives with duo-props. This package provides outstanding low-end torque and slow-speed stability, yet still provides nimble handling at speed. This setup also costs less than the water jet package, while still offering diesel reliability and operating economy. Additional features shown on this vessel include full-height aft cockpit safety rail, aft davit, and oversized pusher knee. 

Choice of the United States Coast Guard


In 2012, Metal Shark won the 470-boat contract to replace the USCG’s aging response boat fleet with its new design, based on the Metal Shark 29’ Defiant-class monohull pilothouse platform. Powered by twin Honda 225 HP outboards, the trailerable, C-130 transportable RB-S II reaches speeds of 50 knots. The RBS-II features Metal Shark’s signature “pillarless glass” pilothouse, which rewards crews with significantly enhanced visibility and safety compared to conventional pilothouse designs using smaller, framed windows. For the Coast Guard, Metal Shark designed the RBS with quickly-lowering side and aft windows, which convert the enclosed pilothouse to an open cockpit for maximum operational versatility. 

The $192 million contract for the RBS-II was one of the largest boat buys of its kind for the U.S. Coast Guard. Metal Shark was selected as one of two finalists for the contract and won out after an exhaustive series of head to head tests proved the merits of the company’s innovation and substantial investment in new technology. Serialized production of the RBS is ongoing at Metal Shark’s Jeanerette, Louisiana production facility, with new vessels completing weekly. RBS production reached a milestone in July, 2016, with the delivery of the 200th RBS-II to the USCG.
