When those plywood cleats happened to be right where a mast pulpit backing plate needed to be, I used a hole saw to cut it back, just large enough for the backing plate to fit. I think the plates were 3″, so a 3-1/4″ hole saw blade is enough. Initially I’d only drill deep enough for the blade to start a groove in the wood, so that the saw’s guiding drill bit did not penetrate into the fiberglass beyond the plywood cleat. Then I removed the guiding bit and finished the cut with just the hole saw blade, which easily followed the groove it had already started. (It sounds more complicated than it is.) Anyway, the result is a neat, clean installation – even if no one ever sees it up there behind the salon ceiling panels – and it left the rest of the cleat in tact. In some cases it was only necessary to take a bite out of the cleat for the backing plate to fit in place, and I was able to fudge the cut without any guiding drill bit at all.

I essentially did the same thing, except I drilled the holes down from the deck where the pulpits were going to be, then used the guide bit on the hole saw to follow that hole. When it penetrates the deck, I used a 1″ hole saw to remove the core and inner layer of glass. I taped over the 1″ hole and filled from the top with epoxy.When epoxy hardened, used the hole in the deck skin to guide the drill bit back down and assembled. Ta da!

As far as one person goes, I could stand on my settee and reach through the hatch to do the thing with a wrench on the nut below and the screwdriver on the screw above.
