Found soft spot on hull after putting on trailer
I own an 81 hunter 22 sailboat. I put her on the trailer this past winter and as I was scraping the old algae etc. I noticed a soft spot and some superficial cracks. When I say soft spot it wasn't as hard as the rest of the hull in that area. I was using my fist to pound around and see what the rest was like.
I dont know how the boat was constructed so I dont know if the area around it was lead or not. I have no blisters and no leaking inside the boat. She was at the marina all summer with no a drop of water inside.
My question is I would like to strengthen the area before painting the bottom and have no idea where to start. Any advice as to the severity of the problem or how to repair would be helpful
