I've begun the process of doing some fiberglass and core repairs on my O'Day 23. I'm new at it, so please understand that in this posted message. My most significant repair is to the starboard stanchion. The base to the stanchion was torn through on 3 of the 4 sides at the base of the stanchion, causing the stanchion to lean, giving rainwater clear access to the interior of the boat. I knew the core would be damaged and needing replacing, which I've started removing the stanchion and gutting out the bad core. At that same time, my son mapping the boat for delamination and other possible core problems. It apepars clean sounding all the way around, the boat, except on the starboard side, just aft of the forward starboard side. So, a second spot with possible problems. The one I already knew needing rebedding was the starboard rear stanchion, will I have to do the other? My question is, why would there be possible core problems on only ONE side of the boat? I've got Don Casey's book on Hull & Deck Repair, yeppers, I'm a DIY (God, please help!) Is there an easy way of doing this rebedding, 'n fixing core problems or is it really that easy????? Mark
