One of the seats ripped out of the transom on my 67' tri-hull. The four bolts came out. All the other seats are fine. So I don't thing the whole transom is rotted, and the boat hasn't been collecting water to be able to get into the sealed transom. So, how do I go about fixing that area of the transom? Is it okay to just put like two layers of fiberglass over the area that the seat was mounted, and remount? Or could I just fill the holes with epoxy/bondo/JB-Weld, and screw the seat back down? I'm planning to take the boat out Saturday, and this happens.
