I built a cedar strip canoe last winter and have enjoyed it immensely this spring. However, on my last trip out I discovered a "problem" that looks really suspicious. I have two small blisters --- (delamination?) on the underside of my canoe. They are in close proximity to one another. One is about 3/4" round and the other is about 2 1/4" long by 1" wide. They appeared this last weekend after I had the canoe out on the water for a little over an hour. This is my fourth time out and I know they weren't there before. (As much time as I spend wiping down and staring at my boat it would be impossible to miss them.) Anyway, when we flipped it over to put it on top of the car I saw them immediately. It doesn't seem like there is any water under them. I think I know what I have to do to repair it but there are two real concerns on my mind. Why did it happen and is this "only the beginning" ?
As you will be able to see from the picture, it seems to have occurred over a piece of cedar that is darker - heartwood? - and probably soaked up more epoxy, starving the cloth and therefore not making a good bond to the wood. Still... with 3 more layers of epoxy (4 total) and 4 coats of varnish, this still seems like an impossibility? I haven't cut into the pockets yet. I have a couple of questions about that. Is it possible to just cut a slit in this blister and fill it with epoxy and press it back in place? (Sand, re-varnish) Or do I have to cut it out completely and patch with new glass?
One more question... I was hoping to take this canoe for a (only 3 days) camping trip in Voyagers. Really been wanting to do that all spring. But this has me worried that a full day on the water would result in me pulling in to camp in the evening to flip my canoe over and find the entire hull bottom covered with air pockets, looking like a leper! What would a person do if they were in the wilderness with another day or so of canoing to do and you found this damage? Is there a way to do a quick "patch" or fix so that you can keep going? How bad is it if you break through the glass and the wood gets wet? Even thinking about fixing this spot has me frustrated with the possiblity of not being able to use the boat for another several weeks as I wait for epoxy to cure and varnish to dry.![Frown :( :(](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f641.png)
Any advice or ideas will be very welcome!! Thanks!
