Innovative Foiling with no constraints

Quite simply, we aim to create the fastest beach launched catamarans, across all conditions and at all points of sailing.

How it Works

Outboard Foil System – Righting moment increases as boat lifts out of water

Canted T-Foils Optimised to produce zero leeway for hydrodynamic efficiency

Active Flight Control A bow mounted moth style wand system for stable flight

3 Point Flight Much less drag by having the windard foil raised clear

Gulwing Deployment Foils are raised for high performance in light winds

Straight Boards Slide them in for lighter airs, shallow waters and for recovering boat


Sailor Testimonials

It’s fair to say the thing’s an absolute beast, genuinely the best sail I’ve had in a long time.

We were doing 22 knots upwind and 27 knots downwind in about 10-12 knots of breeze!


Ben Saxton, Rio Olympian, Nacra 17

This boat is mind blowing, probably the fastest thing I have ever sailed and a serious amount of fun!

The way it has been designed and set up makes it so stable in the gusts and the chop, the scary thing is you can feel how much more there is to come from the concept with future development.

Team Vampire

William Sunnucks

William has been sailing and racing Catamarans internationally for 4 decades, in that time has become one of the most accomplished corinthian multihull sailors worldwide.

The Vampire Project was his brainchild and is described by him as a financially unsound investment that returns a lot of fun.

Kyle Stoneham

A long term multihull sailor and now foiling moth convert, Kyle has been able to bring added refinement to The Vampire Project.

Kyle’s focus has been on technical tuning, sailing technique and future development.

Graham Eeles

Graham is the boat builder and skiff sailor who made the Vampire work.

Based at Brightlingsea he is the fundamental link between the sailing and engineering side of the Project.

Mark Self

Mark has been sailing on and off with William for a very long time, he is the sort of guy you want around when it gets a bit lairy!

Mark’s profession is sail making and his Advantage Sails power the Vampire to ridiculous speeds in all conditions.

Kevin Ellway

Kevin specialises in design and analysis of high performance sail boats, his most notable project is the Exocet Moth which has dominated for a number of years.

The Vampire Project is based on millions of calculations using Kevin’s VPP system which finds the best solutions without the need to get wet!

John Downey

Recently retired, airline pilot John now lives in Cartagena region of Spain, he has become a vital part of the Vampire winter training programme.

John has an array of Catamaran experience including the GBR Tornado squad in the 80s, read about his current A+ wing sail project.

Event Calendar

2020 was a barren year for most sailing classes not least the Vampire. Boat 1 had some rudder gantry mods and a new mainsail with a few shakedown sails when allowed: unfortunately boat 2 didn’t touch the water. We plan to change that in 2021 if covid restrictions allow.

Here are the events The Vampire Project is looking to attend in 2021, lockdowns permitting.

Whitstable Forts race – WYC, UK
Solent Forts – Hayling Ferry SC, UK
Ronde Texel – Texel, Netherlands
Round the Island – Isle of Wight, UK
Piers Race – Marconi SC, UK
Weymouth Speed Week – WPNSA, UK
Ronde om Tiengemeten – Hellecat, Netherlands

Class Rules

“The Vampire rule is intended to give the designer and builder the fullest liberty to innovate, to develop faster and more sailable boats.

We welcome participation and input from innovative sailors anywhere in the world.  If they build something slower we will help them. If they build something faster we will copy them.”

William Sunnucks.
