NO NOISE IS GOOD NEWS
QUESTION: do you have pedestal steering? if so does it "move" ?, if so this means that one day soon, when You untie your dock lines, make a turn up or down the canel, or during a sail, you'll loose your steering, what you have to do is drop your sails set your anchor, disconnect your cables from the sheaves and quardrant, and use your auxillary steering tiller, if you have a tiller, there's no great problem, what you have is delamination of the cockpit floor, the 3/4" thk plywood that's sandwiched between the cockpit floor and the sub cockpit floor, has seperated, get a 1/4" drill bit, put a stop on it, set for 5/16" depth, and drill a hole pattern every 3" centerline to centerline, both horriz. and vertical, buy some West marine 1 to 1 epoxy, with about 15% acetone to thin it out and allow the wood to absorb the epoxy, and fill all the holes, with a sryinge, once dried, cap off the holes with filler, then paint your floor. don't walk on it for at least a few days. good luck
