Sorry for the late reply, but I've been overwhelmed with work.  I didn't 
see any replies to this message, though.

4200 will work fine.  That's what I used under my taffrail.

I'm of the opinion that the chocks shouldn't be taking a load. 
Sometimes a bad lead will put a bunch of stress on them, however.  If 
you through-bolt them, you might want to put on backing plates.  A nut 
pulling through the deck will make a bigger hole than pulling out a screw.

I would guess that this might be an area without coring.  I don't think 
the older boats had core right up to the edges of things.  (That's a 
good thing.)  You should be able to look from the bottom and see where 
the deck is thicker.

Since it's right at the lazarette, it should be pretty easy to grind 
from the bottom (whether there's core there or not) and lay up some new 

Your J-30 owning neighbor is familiar with balsa-core decks.  That's a 
more serious issue than the masonite.

Hope that helps,
