anyone have any dealing with the seating of the suppoet pole for the mast in the bilge on a 33 (77-83)? Mine seems to be blowing out the fiberglass, Its cracked and pushing out on the fiberglass. Was wondering if anyone could give me some info on repairing this problem. It does not seem to be leaking anywhere, but it concerns me for a couple of reasons, one if there is a metal plate imbeded in the floor that might be rusting or corroding and thus creating more problems, like busting thru the hull, or the pressure of the mast causing a drop, thus cracking the cabin top. any input would be greatly appreciated. Also can this be done in the water as I suspect?ThanksBill
