Cleaned up the keel trunk with a hand grinder and a 60 grit sanding disc. The old wooden side supports have a cut out to accommodate the half tube built into the side of the keel trunk. I am going to replace the wood with red oak and eliminate the cut out so I had to cut out the half tube in the side of the keel trunk and rebuild it flat. The top flange in the keel trunk was pretty bad so I am rebuilding that as well. Then will lay a couple layers of glass mat, replace the trunk cap and finish off with a red oak strip along the top.
