VIPER CRUISER HOVERCRAFT
NEW Series 3 plans & kits now available
-------------------------------------------------------------------
The VIPER CRUISER  plan / kit hovercraft is a fully amphibious vehicle capable of carrying four adults and gear across a variety of surfaces including sand, snow, ice and water.

The kit is designed for the "do-it-yourselfer". It is simple and inexpensive to build. Using an epoxy/plywood/foam sandwich and "stitch and glue" construction, the VIPER CRUISER  hull is strong, lightweight and durable.

The VIPER CRUISER  hovercraft kit is constructed using marine plywood, timber battens, Rigid PVC foam, fibreglass cloth and epoxy resin. 

The VIPER CRUISER  hovercraft is ideal for cruising, fishing, exploring, farming and various industrial applications.

See the links on the left of this page for more information on the plans and kits available for the Viper Cruiser.

WHY PLYWOOD

For amateur home hovercraft builders, plywood is the material of choice. Plywood is affordable and easy to use. Plywood has a better "strength to weight" than steel and is much lighter than most fibreglass hovercraft. When encapsulated with epoxy resin, plywood is as durable and as low in maintenance as any other material. Plywood hovercraft can be built with basic hand and wood working tools.

The joining of the plywood is a "stitch and glue" method. Panels are cut to shape from plans and joined together at the seams. A hovercraft can be assembled quickly after all the panels are cut out.

Once the panels are stitched together with lengths of copper wire, an epoxy paste to used to create a fillet along each side of the join. The join is then covered with a layer of resin-coated fibreglass tape.

An important feature of the Viper Cruiser is the addition of "foam sandwich" panelling. This significantly increases the hull strength, eliminating the need for complex frames and structures. Hull strength and durability is further increased with additional layers of Kevlar cloth on all running surfaces.

Almost anyone can build a Viper Cruiser hovercraft hull using this method of construction. The end result is a light weight, strong and durable hovercraft.
