Deck and cockpit bolsters.
Redbeard, that looks exactly like what we do at the shop. Even your shapes are similar to ours. I'm sure somewhere on the Cherubini Yachts web pages you might see some of Dave's photos.
I am in the (slow) process of making these for the stanchion bases. Two bolts go through the toerail flange and two through the deck; between them has to be a race for water to slide through so the inboard bolts will go through narrow bolsters. But be careful-- on one boat (still in the shop) they popped right off, and had to be redone, due to improper surface prep, which is the most vital stage. Use nothing less than laminating epoxy (I prefer Gougeons') and you should be all right.
Recently I have developed the process of installing backing plates and deck bolsters with a thin ring of 5200 about the perimeter and then, when it's sure to be kicked-off, drilling a hole down from the top and filling the inside of that 5200 ring with epoxy. This makes a really solid block of your little pad, ensures against water intrusion (and flex), and ensures permanent adhesion as well. My cleats, stanchion bases, mast step and foredeck hardware are all being done like this. (I did not do the seacock bases like this, but I could have). This is really the right way to reseat the steering pedestal, given that the new base pad is big enough and the backing plate under the cockpit sole is equally strong. Remember to drill or redrill your mounting holes after filling the void(s) with epoxy. And bed the pedestal with 5200.
I was gratified to see that my new cockpit drains will go through solid 'glass and not through core; I was worried about that at first. Having no pedestal I don't have the problem you wheel-steering people have; but it is true that a solid cockpit floor is both structurally and psychologically an asset. The recoring job is not at all hard (given a rectangular cockpit you might just fit in a piece of plywood and 'glass over it-- using epoxy) and it gives you the chance to strengthen the pedestal, which to my mind ought to be as stiff and as strong as a spar... because in some ways that's really what it is.
