I've finished taking out the foam I can get to. What is left is on the sides and under the lead ballast and there is still water in that little bit of foam also. So my plan is to finish my sanding on the outside so the glass can let out moisture that way and burn a 40 watt light bulb inside to get everything dry.
After I get it all dry and build up the bottom of the keel some to further bury the heel fitting bolts I want to add a bulkhead with a cutout in the bottom so water can get back and forth under it starting just in front of the heel fitting to strengthen the keel in that area. When you added these bulkheads were they plywood that you covered in cloth and epoxy or some other material?
