The Cope 11ft Jet Boat is the big brother of the Cope 10ft Jet Boat that has proven so successful and popular. The 11ft boat is 10 inches wider on the bottom and 4 inches taller than the 10ft boat. The 11ft Jet Boat is able to carry the weight of engines not only from a jet-ski, but also larger engines such as a Subaru Engine. The wider bottom gives lower planing speeds and the longer length and taller sides give a little better ride and more comfort. The cockpit is large and comfortable with extra legroom. The bigger engines can give eye-watering performance.
