Ultra Magnum Inboard Jet Boat by Duckworth Boats (2008)

Throttle one up. Now with a wider 7′ bottom, redesigned gunwale, and available 6.0 liter supercharged V8, the new Ultra Magnum is the biggest, boldest, and baddest inboard jet ever! The Ultra Magnum’s Hydro-Flow jet hull accelerates at a stunning rate, achieving planing speed in mere seconds. But it’s hard to fathom how all that thrust and horsepower can be achieved with such smoothness and shear grace. The Ultra Magnum is supremely capable of navigating everything from intimidating whitewater rapids to extremely shallow riffles and wide open lakes. Its styling is unmistakable on the water, highway, and driveway. The craftsmanship is detailed to the point of absolute perfection. It’s no wonder the Ultra Magnum is the flagship of the Duckworth line.
