Some of us will come into contact with hard surfaces at high speed at some point, make sure you carry out a full inquest into the demise of the craft should there be any damage and lets see what real life results tell us.
I have done that with the canoe I made from 1/8th inch wood by bouncing down a white water river for four days. Rick-o-sheying down river without any damage.
"O" By the way .... the river was closed by the authorities right after we left as unfit/unsafe to paddle even for experienced white water paddlers and there plastic boats.
You might of guessed by now , when we pulled off 5 days later they opened it up as we were loading up to go home. The ranger came by our camp and remover the unsafe sign ( River Closed) and put one up that advised to use CAUTION ( Experienced paddlers only) when on the water.
Damages , capsized one time , wet and cold but that was me , the canoe had a few scratches on the bottom of it from bouncing on and off the rocks but nothing to worry about. The graphite and epoxy worked real good going over rocks.
It was some NASTY water in that river , in the main area and even along the banks when pulling out at night for camping. I had to use rocks to hold the ropes when camping since dirt was not there.
By the way , I was not the only person who swam in that river , several of the guys did and even the aluminum canoes ended up with dings and dents in them. I was thinking that is the nice thing about wood , it flexes. It was NOT a fun trip. The camping was great the rapids sucked and that river was nothing but rapids with a 50 to 100 yard smooth stretch , just enough to bail your boat out and keep going before the next mess that would spill over into your boat. Waves at the rapids from 2 to 4 feet high was the normal , a few places higher.
PS.. Am I going back there and paddle again....
....Not in this lifetime
