The Viper 640 is a 2 to 4 person, one-design sports boat that combines the stiffness of a keelboat with the acceleration and planing abilities of a dinghy. It is fun, fast, easy and affordable.
The Viper is light enough to be towed behind a compact car and simple enough to be rigged and sailed in under a half hour. The boat can be launched from a hoist or ramp.
