We had some fun with a canoe we used it as a unsteerable snowracer without brakes. We only hit one birchtree.
My daughter escaped with some bruises and a little pain in one arm. But it didn´t stop her from more turns down the slop.
The canoe managed it well as it is made from pine and laminated with MAS epoxies. It was great fun!

Haha, vilken fart ni fick!
Ungefär 10 km/h eller 6 knop som det heter eftersom det är en båt.
