1959 Penn Yan Magellan
Lapstrake side and Plywood Bottom
My Penn Yan is generally in good shape. However, I have about 8 screws that are loose or have fallen out of the bottom of the plywood up through the keelson / ribs.
It's not as simple as reinserting the screws because heads have either pulled through the plywood and / or rotted out and enlarged the holes.
I have taken an ice pick and poked the plywood searching for rot and it's structurally fine.
I just have the areas around the screw heads that need repair.
Any advice would be appreciated.
