Mint! I had a go on one of Mango's foils one time, they get one hell of an upwind angle in light winds.
2012 foils weight 8 pounds (4 kg all equiped foil only) painless for the shoulder between the car and the sea, the thickness of Max Nocher T bar (vertical bar) is 10 or 12 mm which assures him a superior upwind angle.
Do they beat the best box rule raceboards?
Until end 2011, foil boards were slightly inferior due to the downwind leg
Upwind : better
downwind : inferior
cross wind: equal
Since March 2012, things have changed, and need to be validated;
The first four foils of the worlds could go over 30 knots (Marc Blanc is said to have a Vmax of 35 to 36 knots with his current model)
A new Foil brand is going to be released soon which incorporates these breakthroughs (Remi Delhaye design) mixing high speed and comfort.
maybe in certain winds?
what are they like in 25 knots +?
The foils are not called the magic carpets for nothing
I am not sure wether the race boards would have sustained the worlds last day conditions (30 knots) with as much ease as the foilboards have ...
