    That's a question you should ask your surveyor. He will know the location and extent of the delams and will be able to give you the guidance you're looking for.

    Re: De-lamination

    Based on what I have seen around fittings you need to fix it ASAP. In spot areas not connected to penetrations it is not a problem. On one boat I had the front deck and part of the upper helm were delaminated. The front deck was bad. It leaked at most fittings and at the windshield area size was 10.5 feet wide by 8 feet to point of V at bow. They removed the entire under side of the deck and re-balsa it. The upper helm had one area at a fitting that was soft about 2 feet by 2 feet. They fixed that from the top. They also replaced the head liner in the V birt and new hatch. Cost $11,000 plus tax in 2005.

    Re: Delamination

    Most of the deck is cored with end grain balsa (wood) on a 310, so any delamination is serious in that your surveyor has most likely "sounded" the deck and found a hollow spot. A simple delamination is easy to repair by injecting the void full of epoxy, but one caused by moisture getting into the deck structure usually causes the core to rot. You didn't include photos or a description of where the delamination is, but anywhere near a cut or screw holes in the deck for a windlass, a hatch, stanchions, windshield, horn, rail mounting, etc are usual sources. So the answer to your question is yes, a delamination or rotted core is repairable. A simple delamination is not expensive unless if it can be fixed without tearing out the interior, a rotted core is different and is beyond the ability of the usual "handy" do-it-yourself boater because the deck has to be either cut away back to the areas that are non-skid.....even the very best fiberglass guy has a hard time patching non-skid......then removed to the core can be ground out and replaced, or the interior has to be removed and t he under side of the deck removed and the core ground out then replaced and the area reglassed and the interior replaced.

    Hopefully, you have a small spot needing repair........the bigger the area, the uglier the repair job ahead.

    Re: Delamination

    If it is rotten core you can get it repaired by working from inside the boat. The process is long and expensive. They first cut the glass in the V birth,then gouge out the balsa, then re-balsa. It is called vacumn bagging, then reglass the interior, then new head liner. Based on what I paid, $100 a square foot is what I paid. He did repair one area from the top. They cut the area out, saved the piece they took out, re-balsaed the area, then put the cut out area back. The cut out area, they put a 2" smooth area around it to tie it in. They matched the gellcoat will as it looked the same colour.
    After doing this once I would not buy anyboat with this problem unless the seller was to fix it first.
