Goodall Design F16 Viper/Foiling/Solo

Goodall Design F16 Viper/Foiling/Solo

We are very happy and proud to present you the Foiling VIPER and Foiling VIPER convertible!

Our famous VIPER hulls will be available in different options:
Classic VIPER with standard straight centerboard cases for pure fast sailing in floating mode
Foiling VIPER convertible with straight centerboard cases AND centerboard cases for foils

We have managed to make our VIPER foil, and first testing shows easy, stable and fast foiling, both up and down wind! Have a look at our pictures and videos to see it yourself.

You want to buy a boat to go foiling or sailing? Single or double handed? Recreational sailing or participate in F16fleet? All choices you don’t have to bother about anymore with our Foiling VIPER convertible. Our boat can do it all! We have made the first catamaran that can both foil properly and sail fast, even within class events. The Foiling VIPER is the most versatile catamaran available on the market. If you don’t like to limit your options, this is the boat for you!

Switching between floating and foiling mode can be done quick and without any tools in less than a minute!

For the foiling setup, the Z foils are positioned in front of the sidestays, just behind the main beam. The foils come out of the hull not in the center of the bottom of the hull, but a little on the side, which allows better foiling performance! The rake of the foils is easy to control with a belt-system, like most Acat’s are using nowadays. The T rudders have a removable elevator on the bottom and the rudder stock is a carbon cassette that holds the rudder tight with clamps.

With the Foiling VIPER, you can sail in any mode you want: foiling, floating.

Why have we chosen for a foiling VIPER convertible with two types of cases? Because we don’t want to make any compromises!

The straight centerboard case stays at the exact same spot as it was in the past, and gives you perfect performanceand balance in F16 and floating VIPER mode. When sailing in floating mode, perfectly fitting plates will make sure the foiling case is closed and the hull keeps his hydrodynamic quality. When in foiling mode, the off center foiling case, which is located more to the front of the hull, offers all the benefits the platform and Z foils needs to easily put the VIPER above water surface and go fast, very very fast! Both configurations can be sailed without having one option compromising the other. It gives you the best of both worlds!

We already have 2 foiling VIPER (1 convertible) ready to sail/foil, 1 in Australia and 1 in Europe.
