I have seen this covered in bits and pieces in other threads.
I'd like to move the jib cleats to the CB trunk using harken 365 carbo blocks. They recommend attaching them with #10 screws. They don't specify machine or wood, but I would assume machine since they need to go through the Cam Cleat itself.
So I see it as I'm left with 2 options through Bolt or drill and tap.
Through bolting is stronger but how can I get up in the trunk w/o removing the CB? ( the boat is already careened in the backyard)
Drill and tap- I've never done it before I would assume use a standard drill and tap kit for 10X24 and drill down 3/8 -1/2 inch and tap it add a little 5200 and screw in the cleat?
My concern is strength and how to tap fiberglass, I'd rather put the work in now rather than deal with a major repair later
