Bill,
Sorry about the slow reply. I work as a tax preparer and this is the busy time of the year.
I realize now that I swapped the term river and rapid. I was under the impression that a river classification was determined by the rapids in each section of the river. The North Santiam River has everything from Class 4 rapids to placid sections great for family floats in tubes and other inflatables. The section we usually raft tend towards the lower end of the spectrum. Not like the rivers in the Adirondacks where I grew up.
Anyway, I looked at your build website and really like some of your innovations. The lash/attach points looked really easy to do and the skirts looked like a great idea when the wind kicks upon lakes where I would use it for fishing. I like the idea of adding flotation to the ends of the boat. I can see my grandkids swamping the canoe and would like to make sure it will stay afloat.
