The Futura hull (a Zodiac® patent) is a perfect technical combination of Zodiac know-how. It comprises a large diameter keel and two detachable, perfectly proportioned, cushioning inflatable tubes, under the boat (inflatable from inside the boat). The result is a fast, comfortable ride since the speed tubes reduce surface drag and absorb bumps from choppy water. The hydrodynamic lift and reduced drag resulting from this design allows Futura to plane easily, even with a full load, and to reach remarkable speeds with only moderate sized outboards. Stable, the Futura tracks straight and true and without sideslip or cavitation.
