Thanks Bones, I find this sort of thing enjoyable. And I actually enjoy researching the projects almost more than doing them. My only issue is that I seem to do these such that my boat is disabled during some of the best sailing weather! It was in the 80's yesterday. I will look into Coremat. The Bluewater product from Coosa (or maybe I have that reversed) looks like a structural fibre glass layup or pretty solid stuff. The area is not too big and I think I have found most all the wet core. Sometimes it is hard to tell until you take it out and try and squeeze it. I had to knock off before I was quite done but I will go back this week. What I still do not understand is that the area under the mast or the ceiling all through that area does not touch the boards that look like a compression post (even though they only tie into the floor liner, not the keel so they are not really a post) and the ceiling does not touch the bulk head nor is it tabbed to the bulkhead. I assumed that bulkhead was there to carry the mast load. And the only place that bulkhead is tabbed or attached is the port side hull. It simply rests on the floor liner. Kind of a strange arrangement. I can tell from the damage that the mast was pushing down but I did not find much really rotten core and nothing was delaminated. So it is hard for me to tell exactly why the structure had a failure except some small amount of the core directly under the tabernacle lost its compression or structure and maybe its lamination. But not much which makes me think that I should overbuild the repair. Robbin On 4/13/2014 11:42 PM, bownez@juno.com wrote:
Hi Robbin,
Was all the damp balsa isolated to the area you have exposed? If so, that should be a very manageable repair. I used a product called Coremat when I rebuilt the foredeck of my M17. Good luck with everything, once again, owning a sailboat is a long learning curve! Keep us posted please.
