I saw a canoe with the inside of the bottom floor only wetted out. I was told it was for more grip action when sitting. Is this a pratice that is normal? I am building the double micro bootlegger and was thinking about doing this myself. But will take away from the strength of othe floor. Do I need to put on the last coat of epoxy to get the strength needed?

Thanks,

Marc

Marc-
I do this (no fill coat, or incomplete fill coats) sometimes, inside the kayak and I always did this on the canoes I built. As long as there aren't any pinholes or other problems with the glass lamination stage, fill coats aren't required for strength, IMO. I don't think there's much point adding extra weight without a reason. I wouldn't do this in a high-abrasion area - or if I did, I'd keep a careful eye on it to make sure the glass wasn't exposed to water, with wear.
Last week I did a small repair on a friend's boat - he's a powerful paddler and had worn through the Wilderness layup with his heels, enough so that the main glass layer was exposed.

And, as you say, it's less slippery without fill coats.
Using peel ply will also give a nice non-slippery finish.
