I don't believe that it's necessary to go to to the trouble of large backing plates for the pad eye. The forces on the pad eye are lateral, not vertical, as the aft end of the pole is pushed into the deck. So just using bolts with washers should be sufficient.
I'm 90-some% certain, that when he says cleats, he's referring to his bow cleats. As on a good number of designs out there, when they're laying up the boat, they laminate aluminum plate into the deck where high load hardware
is to be mounted. And then, once the deck's "done", they drill through the glass, tap the aluminum, & bolt on the cleats.
I can't says as I'm a fan of it, but it's how many builders do things.
Though if he's just mounting a padeye, such as in your image. Then the more significant issues will be where the downwards compression
, & side loads get resolved. Both via the boat's deck, & internal structure.
