Each Metal Shark has been designed to accommodate a wide array of mission requirements, and the easily trailerable, highly capable 21 Relentless patrol boat is no exception.

With its unique progressive-deadrise hull design, the 21 Relentless can traverse the shallows with ease, while still providing a comfortable ride in rough seas. Constructed of heavy duty 5086 aluminum alloy, it is rugged, tough, and ready to take on whatever comes its way.

Like the larger 24 Relentless (standard platform for the US Coast Guard SPC-SW response boat) this versatile 21 features a roomy layout and wide gunnels for 360-degree accessibility. Forward, you’ll find a dive relief on both port and starboard sides, facilitating on-water boarding or personnel recovery operations.

The 21 Relentless can be fully customized to suit a wide range of law enforcement, security, and response mission requirements. With an optional equipment list including dive tank storage, towing bits, gun racks, electronics packages, a foam collar fendering system, and more; Metal Shark will tailor the 21 Relentless to your exacting specifications.
