More pictures in the links on my skate sailing page. On request commercial users can receive some ten more pictures, and a little more on the perils of skate sailing, via Internet. Jagged ice walls and open water send adrenaline levels soaring. Long distance sailing on ice with invisible spots of too thin ice is deadly as Russian Roulette. Wings are crashed to pieces.
Sailors wear life vests, ice prods, plus protection like hockey players.
Extreme arctic climate, chill factor -50 degrees C. Equipment is free. Skates 90 cm high have been tried. Racing has been organized for 100 years. National championships are sailed yearly. Great variety of slides.
