Hi there, I recently acquired an older OT Tripper and was directed this way from another forum as a possible means of looking up more info regarding this boat according to its serial number. It's a bit hard to read on the hull but I believe the code is XTC45730M83B. I think it might be old enough to have some scanned documentation. I got it from at least a second owner who never used it, and the owner before that replaced the thwart and yoke with 2x4s and what looks like trex decking screwed into it. The canoe is otherwise in decent shape and I'll be restoring it in the next few weeks (proper thwart and yoke, adding cane seats) for a few camping trips this summer. Thank you so much!
