Yesterday I removed some interior lining on my Cal 2-27, both to replace some old, stained material and also to find and stop some relatively minor water intrusion (the cause of the stains.) I had assumed that the water was coming from some poorly sealed stanchions, but discovered instead that several screws had poked through the hull. These screws are used to hold the rub rail in place, and were intended to go vertically through the hull-deck joint, but some of them ended up pointing inward and piercing the hull (Note: I doubt this is the original design. Are your rub rails screwed in place, or just secured at either end? I have a screw about every foot or so.)
Anyway, I'm wondering the best way to do this repair. I'm weighing:
- Just plugging the holes with a sealant
- Injecting epoxy into the holes
- Covering the holes with glass patches
Any thoughts? I don't see any signs of breakdown surrounding the holes. Not that I really know what to look for, but other than the water itself there doesn't appear to be any damage surrounding the hole.
Here's a picture. The light, horizontal band running through the holes is the hull-deck joint. The dark section above that is the horizontal bottom of the deck, and everything else is the vertical side of my salon. There are about 8 holes in this section, and this is the worst area on the boat for this problem.
