The Goodall VIPER is the ultimate sports car

With over 30 years of catamaran design experience and the latest in design software, the VIPER was designed for high-performance racing catamaran teams who were just too light to mix it in the F18.

Ideal for mixed or youth teams, the VIPER is light and responsive in every aspect and this will give you the speed and excitement usually reserved for the bigger boats of the fleet - and you'll beat them across the line in most cases too.

The Goodall VIPER is the versatile Sports Car that can be sailed either 1 or 2 up. By simply leaving the jib off, sailors have the ability to sail and race if their crew is not available.


Versatile sailing

The Viper is an ISAF recognized class and can be sailed under the strict one design rules, or sailors can race under the F16 box rules

Its Epoxy construction makes for a durable, long-lasting boat and EVA deck grip means you and your crew will move with confidence around the platform.

Highly precise gybing centerboards increase upwind angles and decrease hull drag. This coupled with the fully battened self-tacking jib, fully integrated wing mast and mainsail gives teams the up wind advantage.

This highly efficient rig is one of the most developed in the class. With a specially designed wing mast section to suit the boat and crew weights you will have the versatility to sail fast in almost any condition.


Fast, light and responsive

A high-speed boat needs responsive control. Not only do our Goodall Design low-drag rudders provide ultimate grip at high speeds, but also provide amazing low-speed maneuvering for those start line duels.

The VIPER Control systems are ideal for smaller crews; 16:1 cascading downhaul, 10:1 mainsheet and top end Harken running gear make the controls of this sports car as light and easy as possible

The Viper is the ultimate sports car, don't settle for anything else.
