The symmetrical daggerboards are canted inwards and angled forwards to help induce twist. The windward foil is vertical when the hull skims the surface and is designed to act as a gybing board; at the same time the leeward foil generates vertical lift ingenious!
The rig rotates for aerodynamic efficiency. The hi-tech Mylar sail has a "fat head" for power, but a relatively conservative leech for gust response and ease of handling. The enclosed gnav and wrap around luff sleeve further reduce aerodynamic drag. Lower shrouds give precise control of mast stiffness.
The uniquely slim tunnel hull form of the Vortex hull combined with high aspect foils gives a very low wetted surface area, especially when flying a hull. Less drag = more speed!
Righting moment is a function of weight and distance from the centre of buoyancy. Due to the tunnel hull, the centre of buoyancy moves to leeward when the Vortex heels, dramatically increasing the righting moment. More righting moment means that the full power of the rig can be applied, even in stronger winds.
"Handling is direct, precise and incredibly responsive .. this boat was designed for me!" Says Phil Whitehead, National Champion 2005,10-13.
