NOPE......... If you are talking about where the deck and sides meet.
Ran a 1/4 by 3/4 inch strip of redwood just under the seam on the side boards so the deck sat on that when flush with the side boards , then ran a good amount of epoxy along there to epoxy the deck to the strip along the sides.
Might say I taped the interior seams but it was with the 1/4 by 3/4 inch redwood strips and epoxy ... not fiberglass tape. There was no way I could tape the interior seams because of the length under the decking that could not be reached. If I would of put hatches in the decks then it would be possible to do that.
The distance from the aft bulkhead to the stern is 72 inches. The bow section is a little shorter but not by much.
The seams on the panels for the bottom and sides were filleted but not taped. The fillet is about 1 inch wide. Remember the inside was epoxy saturated with 4 applications of epoxy.
The 7.50 oz glass on the outside handled all of that for me when the boat was together, no oil canning from the bottom and I did run up on a log ... just to try it.
As I said when I was making it , I wanted to try something different and see how it worked. If you don't try it then you will never know. "O" by the way I strapped it down on the rack really hard (it compressed the rubber I have on the bars ) without any problems. and it was bottom down , deck up because the coaming will not fit between the bars on the roof rack.
If I did it that way the coaming would be supporting the boat and not the deck. Remember a Jeep Wrangler is not a real long vehicle. Actually it is short sucker made for running thru the woods so the roof rack is rather short.
