With a top speed around 110 mph, 170 km/h, this may be the the design for a world speed record contender for ice sailing.
Normal course racing wings starts to over power you at their top speed of around some 80 mph, 125 km/h, in a wind of 16 knots, 8 m/s.
This high speed design has half the sail area and should start overpowering you around 110 mph, 170 km/h (square root of 2 = 1.4 higher speed). Not twice as high because wind forces increase with the square of the speed.
I have some thoughts on real fast skate sails, world speed record, 130 mph, 210 km/h, designs at: https://sites.google.com/site/wingskatesailpict/ More, incl. building/sailing instructions, for ordinary wing sails, and an article for reading: https://sites.google.com/site/icewinghomepage/
I call my sails Ice Wing.
Ice skate sailing is a dangerous high speed sport: thin ice, drowning, collisions, crashing into land, get thrown onto the ice by a misbehaving prototype: "It was sad that we never got to know each other" said one sailor after the wing got smashed into pieces on the first sail - bu no fatalities in Sweden so far.
Contrary to other ice/land/snow sailing concepts this design has no extra aerodynamic drag from planks/hulls/sailor etc.
Wing still in testing phase.
Test pilot: Dick Tillberg.
