The Viper 4S is a enhanced version of the Viper 4, with many inclusions that provide improved comfort and performance.
The Viper 4S, like all our hovercraft retains a beautiful finish, with well layout features that provide comfort and safety. It is simply a joy to fly without the need to for full power, or struggling in high winds or large chop.
The Viper 4S is manufactured using the best materials and engine. The hull is light just by design and incredibly strong, by taking advantage of high end fibreglass fabrics, resins and fabrication techniques.
The Viper 4S incorporates localized Kevlar reinforcement which provides weight reduction, whilst adding additional strength and durability.
The Viper 4S Hovercraft is a stable floating platform for fishing, diving and retrieving. Our positive buoyancy system ensures a unsinkable Hovercraft, even if it is completely swamped. Easy passage to all interior deck areas, gives this design the edge over all competitors.
The Viper 4S is powered by either a 65hp, inline two cylinder, air cooled aircraft engine or new for 2018, the latest "Spec 2" water cooled two-stroke aircraft engine setup.
The Viper 4S model has the larger Series 5 fan duct, flow vanes and elevator system which provides excellent performance at lower fan speeds. We have also included our own unique driveline dampening system, which increases engine and drive system life.
