tfrei Posted June 1, 2021 Report Share Posted June 1, 2021 I was putting on the main mast on my CS 17 and stepped back on to the seating area of the boat and heard a crack. See the damage below. It is on the step area just forward of the centerboard trunk. I was planning on sanding the area down and putting down a strip of fiberglass and epoxy and maybe wrap it around the edge. Any further ideas or advice for this repair? Quote Link to comment Share on other sites More sharing options...
Dnjost Posted June 1, 2021 Report Share Posted June 1, 2021 Add a backing block behind it, then screw and glue it. If you have any 3/8 marine ply left that would be perfect. If not, use some3/4" fir. 1 Quote Link to comment Share on other sites More sharing options...
Peter Batchelor Posted June 1, 2021 Report Share Posted June 1, 2021 I'll second David's advice. I don't think a strip of fibreglass over the top would solve the problem. A piece glued to the bottom of the seat, covering the split area by at least a few inches, would be your best option. Then, perhaps you could send back the top of the seat, scrape out along the crack to open it up a bit more, wet it with epoxy, and then fill it with a fairly runny mix of thickened epoxy. Wait an hour or two, and scrape off any excess so that you don't have to sand it off later. You might need to repeat the process, perhaps with some sanding filler instead of a glue filler, and then sand again, before coating the area with clear epoxy, and then repainting.

Hirilonde Posted June 2, 2021 Report Share Posted June 2, 2021 It looks like the plywood was just butted. What David and Peter said. Quote Link to comment Share on other sites More sharing options...
tfrei Posted June 2, 2021 Author Report Share Posted June 2, 2021 Thanks for the help everybody. I think I have a good idea of what to do now. Quote Link to comment Share on other sites More sharing options...
Reacher Posted June 2, 2021 Report Share Posted June 2, 2021 tfrei, I suggest you also inspect the end of the support piece that runs under the front of the plywood step—where it butts up against the centerboard trunk. It might be that that end is loose and sagged, causing the plywood seam to pop under load. Just a guess from looking at the picture. A great thing about the boat is that there isn’t anything you can’t fix. Quote Link to comment Share on other sites More sharing options...
