I just built a kite ice boat for this winter season. All that's left to do is paint it, connect the springs, add cables, and pad the seat.

The blades were salvaged from my old home-made ice sailboard. I may make larger ones so I can go in snow as deep as 2 inches.

holy moly! Can't wait too see a video of that thing in action...make sure to measure the speed.
And be sure to have a very good protection!

You'll shoot your eye out with that thing!

I took some of the inspiration from that. I saw it used in a Youtube video called "Ice Kite Buttboarding".

But I think mine will be faster, because it gives me more leverage against the kite.
