I'm not sure what I did, or what if anything I need to do about it now. After the initial float of my Auk in November I put the boat in the basement and put 4 coats of varnish on it. After the first two times I paddled this year, I checked the bottom of the boat for marks, and found what I expected, scuffs, and light scratches from launching and returning. I checked the bottom today to see if I had many new marks from Sunday's paddle. I didn't expect to find what was there. On the keel joint there is a raised weave pattern about 20" in length, varying in distinction. Two seams over there is another raised weave pattern about 4" long. There are two end scarf joints the same way. Nothing visible on the inside, and it didn't leak. I don't think it could actually be the glass cloth, just the pattern in the epoxy, but not sure.
Before I took it out, while it was sitting on the grass, I carefully! stepped in it to adjust the position of the foot pegs. I didn't hear or feel anything, but that is the area of the bottom where the weave pattern shows. The only other thing that comes to mind is, I didn't realize it when I put the boat on the truck, but the roof of the dark blue truck was painfully hot when I went to put the foam under the boat before cinching it tight. I'm looking for info on what somebody thinks I did, and what I should do??????
Thanks for helping.
