Good for you SG.
"It's pretty clear that the gunnels probably won't survive long term use.
So I decided to add a layer of glass tape, in the areas where the gunnels will be bouncing around on a roof rack."
It is a good thing there are no "I told you so" types around here. I am strapping my canoe without thwarts, but with CF gunnels, 2 layers + kevlar + glass to an Otter tomorrow and I won't be concerned. Off to lake trout land in WCPP. Pretty pumped about that. Flying in and paddling out. It has been a grind of a year so I thought I deserved the fly-in.
Gorgeous canoe. Great to hear that it is a keeper!
