soft, spongy cored decks - repair method and costs?
First, as most are suggesting, such deck repair is not simple job.
However a friend of mine had already purchased an Ericson ('60s vintage) before he discovered it had spongy cored decks through out. This, in spit of the fact that he had a complete survey prior to purchase that didn't mention the problem. So far, I'm surprised no one has suggested repairs from the outside. This is how my friend did his. Saved having to take the interior apart and all the related glass mess inside the boat. My friend was living aboard at the time. Also eliminates the need to do overhead glass layup. With grinders he cut out section of the deck glass, from topside and just down to the cores (ended up being 100% of the total deck area), cleaned out the old rotten/soggy core material and rebedded new core foam to the old interior glass work. Since the deck cores generally -- My opinion and experience. FWIW Steve s/v Good Intentions terminate just short of the bulkheads, each section that he removed ended up running from bulkhead to bulkhead. Once the section of core material was inplace, he layed in the first couple layer of mat and roving, leaving the final layer to be accomplished after he had all of the adjacent areas recored and glassed in. When completed, smoothed and faired, he applied the non-skid patterns from sketches and measurements. I think he used crushed walnut shells, set in resin or paint. He estimates that he added a few hundred pounds to the the deck weight but no more than the deck weighted with all that water in the core. BTW, this fellow is a lawyer and this was his first boat. The surveyor was arranged by the broker.. My friend took the surveyor, the broker and the seller to court but the judge throw it out.. Kinda like "Buyer Be Ware" when purchasing a boat that old. |
