I was going around my bottom touching up the sanding done before barrier coating, at least someday I hope to barrier coat. I had seen cracks around the front of the stern tube on the bottom. Boat yard said just in fairing probably. Well everything all ways seems to be worst case on this old 1976 Cal 2-27 I'm trying to rescue. Previous owner said, well never mind what he said it was all lies. I wonder what he was thinking when he did things, like Teflon tape on flare fitting on fuel valve.
Anyway I decided to grind back to redo the fairing and found a void just below fairing and gelcoat that opens under stern tube. I assume trapped water froze and popped the area ahead of stern tube. So I'm thinking of creating a dam after cleaning up inside and let epoxy run out and fill void. Then grind down and epoxy with mat around area on bottom. There shouldn't be a load here, correct? If this would have opened it would have been a almost impossible to plug.
Also I have a low area that holds water behind the backing plate for the strut. Should it flow under it or is this a design flaw?
