this sucks really bad.
I was thinking of carrying a rope on me, so if you know your ski is sinking and dont have any help you can tie it up and let it sink and youll have the rope attached to the ski, but the more I think about it, how the heck are you going to tie a knot while your ski is sinking ( i dont ride is more than 30 feet usually, so it wouldnt need to be that long)
