I inherited my dad's 1960 Barbour. Not sure on the model, but it's a 17' lapstrake (red oak). I know how to drive boat's but no nothing about repairing them. Here are the issues and my questions:
1. There was significant rot in two of the strakes where it meets the transom such that I cut out the bad section resulting in a 4"x6" hole. This is the bottom two planks and would be below the water line. I know I probably should replace the planks, but not sure how to do it, where to get the red oak, etc. For now, I have cut a piece of 1/4" ply and screwed the "patch" to the back inside of the planks, which would be followed by another layer which would run flush to the existing planks. I was then sealing with some West 105/405 epoxy then read that's not the best thing to use since it will likely crack once exposed to water.
a. what else can I do to fix this hole? Should I use 5200 instead or perhaps Life seal? Is the ply patch a bad idea?
2. The overlap of the planks underneath were sealed by some caulking (perhaps 5200?), but the seams are all cracked along with the paint. I was going to scrape these clean and seal again, but not sure what caulk if any to use.
3. Someone suggested I use G/flex for the repairs I am attempting, but I am more confused the more I read.
Again, I know little about wooden boat repairs, but what little I've read says that lapstrake planks need to flex, so epoxy of any kind is bad. I can see the planks are attached on the inside to the ribs with screws. I assume the varnish on the inside also provides a seal against water intrusion. Anyways, what started as a little vacuuming, washing, poking and proding has led to quite a task, but I am up for it as I have many memories with my dad and the boat and want it to "live on". thanks.
