    Metal Shark introduces new Swamp Shark propulsion system

    Louisiana, USA based boatbuilder Metal Shark has partnered with Angelle Development, LLC of Breaux Bridge, Louisiana to introduce an entirely new vessel propulsion system featuring patented technology and several industry firsts, the Company said in a media release.

    The “Swamp Shark Drive” is an all-terrain propulsion system specially engineered and built for operation in extreme shallow water, riverine, and mud flat environments. The highly durable system will safely and reliably propel a vessel through dense vegetation, mud, and debris-strewn waters.

    Originally designed to allow fishermen and hunters to access the extreme shallow backwaters of Louisiana’s Atchafalaya Basin, Metal Shark executives saw potential advantages for military and commercial operators. The system has been tested and proven on Metal Shark test vessels throughout the research and design process.

    The Swamp Shark propulsion system consists of several key components: A CNC-cut, machined-steel surface drive, internal/external stabilizing hydraulics, and a specialized internal cooling system, all of completely original design.

    Swamp Shark drives are currently available in configurations capable of handling up to 550 propshaft horsepower and 1,250 ft.-lbs. of torque, all while operating in extreme conditions. The specially-designed outdrive with custom cavitation plate features hydraulic power trim and steering, and its stainless steel surface-piercing propeller easily powers through mats of vegetation, bushes, or branches, while offering outstanding control on open water even at high speed.

    A patented hydraulic / electric rebound system, which consists of actuators inside and outside of the vessel, allows the drive to smoothly and automatically adapt to conditions. When the drive impacts a solid object, such as a log, stump, or other submerged hazard, it swiftly “kicks up” so that the propeller will not be impacted. The system then exerts reverse pressure to instantaneously return the drive to its normal trim position as soon as the object has been cleared.

    Swamp Shark features a fully self-contained, patent-pending, onboard keel cooling system, with no appendages beneath the hull and no need for overboard raw water. This allows for smooth operation over underwater obstacles and allows a Swamp Shark-propelled vessel to traverse shallow, vegetation-clogged water or even loose mud with no cooling issues. The highly-efficient system cools engine oil, power steering and transmission fluid, and also boost-air intercoolers for turbo or supercharged engines, all with no reliance on outside water.

    Swamp Shark Drives are available in a range of sizes to accommodate a variety of gas and diesel-powered boats for military, commercial, and extreme recreational operators. Metal Shark is the exclusive OEM installer of Swamp Shark Drives for military and government agencies.

    Established in 1986, Gravois Aluminum Boats LLC, and its government/commercial boat entity Metal Shark Boats are leading suppliers of custom boats for defense, law enforcement, and commercial entities. Key customers include the United States Coast Guard, Navy, Air Force, Army, foreign militaries, law enforcement agencies, passenger vessel operators, pilot associations, fire departments, and other operators worldwide. Under the direction of its owner/operator Allard and Gravois families, Metal Shark has produced over 500 vessels in the past three years at its two fully self-contained South Louisiana production facilities. Metal Shark produces a wide range of custom monohull and catamaran vessels up to 250’.
