Deck delamination issues
Bryan - ANYWHERE hardware is fastened to,or thru, a cored deck, cabin roof etc there will eventually be some moisture getting into the core. On more expensive boats this problem is addressed to some degree : the technique is called "potting" and it involves removing some of the core adjacent to the fastening hole and injecting a thickened mixture of epoxy, then re-drilling the hole for the fastening when the epoxy has cured. The new hole will be passing thru the epoxy plug and moisture will be unable to get into the core to cause damage. Obviously this adds to the production costs and is not something apparent to potential buyers, so lower cost boats like O'Days skipped this detail. Apparently Hinkley's and other boats in that cost bracket do this during production, which is one reason why they're so much more expensive. After the boat is built and the cabin liner, cabinets etc are in place it may be difficult to access some of the areas to effect repairs, but for the most part it can be done though it's a labour intensive business that may require a fair amount of ingenuity. The material costs are minimal, but if you're paying to have the work done it can run into a lot of $$$. Even the best of caulking or bedding material will eventually allow some moisture to get into the core over time.
