De lamination in floor between fuel tanks?

The picture helps, but a wider angle image showing more of the boat to give perspective would help as well.

First, thanks to Tyboo Mike for setting up the album and to Jim for your generous offer of help. You can barely feel the brown ridges above the surrounding fiberglass. They appear to be wood. The area peeling is about 2 x 3 inches, although it looks thin and worn in a larger area. I checked with a toothpick and then with tip of a sharp wood screw and the entire peeled area is hard. Paul

I've added another picture in my album to better show the location of the gel-coat flaking. Thanks to everyone helping. Paul

On the right side of the photograph there are telgraphed shadows of the mysterious (to me) red stripes. My best guess for the origins of your problem is moisture/water/vapor causing the not-so-flexible gelcoat/paint to release its' bond and flake off. Anytime any paint/gelcoat behaves in this matter, no matter what surface it is applied to, always---always---always suspect some form of water. Always.

If this is hard, then there is still glass over the balsa core, and it is just superficial gel coat/paint peeling. The bond on this inner layer is not as strong as the laminate. I would just watch this area--I agree you want to keep it as dry as possible.

It doesn't look like delamination in the sense of the hul breaking down, it looks like poor adhesion of the finish coat to the glass work.

This should be easily fixed with sanding and reapplying the finish material (gelcoat or paint as required).

This area is the lowest point in the boat next to the bilge pump well. It is very common to have a small amount of water sitting there. I have an elevator style boat lift and I keep the bow raised but a tiny bit of water still puddles here in front of the bilge pump well. Has anyone else with a CD 22 had a problem with gel-coat in this area?

That doesn't look like a major (or even a large minor) problem. It's just a Boo Boo. (A technical term to an Electrical/Naval Engineer used to ship problems).

Grind it out a little, feather the edges and put down some epoxy and let it get hard. Dr. Bob will elaborate when he sees this... Mr. Green

May all your boat problems be this size and magnitude!!
