The balsa core in the forward coach roof was wet and rotted around the hatch and under the mast step so I cut away the outer layer of fiberglass and removed the old coring until I hit solid dry material. I filled the cavity with solid epoxy mixed with a microfiber filler and shaped it to it's original form. It created a rigid structure for the mast step and made the hatch cutout virtually water proof. I also eliminated the horizontal portlights by glassing them over and cutting in round ones. Now the deck feels stiffer and the round ports give the boat a sort of retro modern style.
Area around hatch and mast step.
Horizontal portlight slots glassed in and faired.
