Viper 4 Series II

Viper Hovercraft

The Viper 4 Hovercraft is our high end, 4 person base design which is ideal for fishing, farming, industrial and recreational use.

The Viper 4 is a light, simple, robust design, making it ideal for customers with high expectations, but with cost in mind.

The Viper 4, 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 4 is manufactured using the best materials and engine and fabrication. The hull is light just by design and incredibly strong, by taking advantage of high end fibreglass fabrics, resins and fabrication techniques.

The Viper 4 Hovercraft ia 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 4 is powered by a 625cc, low revving, two cylinder, 55hp two-stroke air cooled engine. This engine has high torque, a flat even power curve, which offers excellent fuel economy with low noise.
