With its wide 14-degree hull, the Advantage Inboard attacks shallow water with the performance you expect from a Duckworth. And getting on plane, and staying there, is of little consequence. The 18' and 19' Advantage Inboards feature a GM 305 cubic inch, V8 engine that produces 280 horsepower-a perfect thrust to weight ratio for a boat weighing less than 2500 lbs. The 20' and 21' Advantage Inboards achieve optimum performance with GM's 350 cubic inch V8. With 310 horses powering the American Turbine SD-309 jet, you get a fast, smooth handling boat. The Hydro-Flow hull comes standard, as does the HD intake and stainless rock grate. The Advantage Inboard is as comfortable as it is spacious. The interior features are nothing short of exceptional. The seating is signature Duckworth quality, as is the heavy-duty convertible top. With so much versatility going for it, it can go virtually anywhere. When you're along for the ride, just remember: take only pictures and leave only wakes.
