Yesterday I made a grievous error on my Waters Dancing Trillium 21. My workspace is small, so I took the deck and hung it from the ceiling of the garage. Seemed like a great solution to get it out of the way temporarily. But I forgot to figure in the garage door opening. The result is a full fracture on one side of the stern deck. See photos. EDIT: Turns out I can't post pics, so here's a description: The fracture is adjacent to the stern hatch opening, on one side only. It is full thickness and the edges are separated, ie. completely broken.
I epoxyed and clamped the fracture last night, let it cure 12 hours, then sanded the top and just applied a patch of 4 oz cloth. It looks reasonably good. Once that's cured I'll turn it over and be able to put a more solid patch on the underside. So question: What will be best to apply to the underside? Fiberglass tape, a couple of layers of 6 oz cloth, or maybe a piece of plywood? I would love your thoughts on what to do to the underside of the deck in order to fix my serious screw up.
