The trickiest part will be to restore the seat surface to original pattern.wingssailhttps://www.blogger.com/profile/13170619136224079532noreply@blogger.comtag:blogger.com,1999:blog-1659347282261955663.post-38326064775902769432015-10-27T06:07:27.513-07:002015-10-27T06:07:27.513-07:00Thanks for the information, Fred.

The big thing to figure out is how to clamp it together since I can't get inside the seat. I think I have come up with a way to do this.Jimhttps://www.blogger.com/profile/11116243753357496034noreply@blogger.comtag:blogger.com,1999:blog-1659347282261955663.post-41134750629159154362015-10-26T17:29:15.978-07:002015-10-26T17:29:15.978-07:00Many boats have cored composite decks and other ho...Many boats have cored composite decks and other horizontal pieces. The core material is not exactly reinforcing, it is just there to separate and hold firm the two skins. In laminates like this the core material (plywood blocks, balsa blocks, foam, or whatever) is simply there to keep the two skins, top and bottom, firmly placed and separated. The strength is in the skins, one in compression and one in tension, the distance apart they are, and how well they are held in place. A two inch thick section of paper honeycomb would be stiffer (and lighter) than 1/2 inch of sold plywood. No reasonable thickness of built up lamination of roving would produce a solid seat without weighing a ton, so the cored approach is the way to go. But if either skin becomes detached, or the core loses its integrity, the panel becomes no stronger than either of the two skins. In your case it seems the skins were not saturated with resin and not completely attached to the core, but the approach was sound.<br /><br />I just finished repairing the cockpit sole on my boat; similar construction except that the core material was balsa, not plywood and it failed due to water ingression which caused the balsa to rot. In my case a three square foot area became soft and all of the core had to be replaced. I cut the top skin with a right angle grinder, removed the section of skin, dug out the old core and cleaned up the area, put in new core (pieces of solid board, pine does nicely) with a thick paste of epoxy resin and high density filler. Then glued the top skin back down with more epoxy paste and repaired the cut with fiberglass mat. (Well ,I am doing that, it isn't finished). Next I will fair it and paint it. <br />This is not the first repair like this I have done to the boat. It is messy and time consuming, but it is simple and it works. <br />Good luck with however you proceed to fix this.wingssailhttps://www.blogger.com/profile/13170619136224079532noreply@blogger.com
