Re: CS30 Structural Grid Repair In Bilge
When a fiberglass boat is damaged the cracks are easy. They're obvious and not difficult to estimate. The real, and expensive, part of the problem is delamination. At the top of the trailing edge of that keel, there was enough force to bend the keel and shed whatever coatings (gel coat, paint, epoxy sealer) were in place. When the glass is deflected that far you can bet it's delaminated. my guess is that the delam is probably on the order of 12 inches across and 10 inches fore and aft. Basically, the same goes for the grid. Cracks are cheap, delams, not so much. Forget the surveyor, get a qualified glassman and don't stop grinding until you've reached the perimeter of the delams. Otherwise, it's like building a house on sand.
