Whats your thoughts on bedding in the new g10 bulkhead. Looked like you glued it down with epoxy
? I vaguely remember old talk about bonding bulkheads onto foam gaskets rather direct to the hull to reduce the point loads and allow the hull to flex? Directly bonding seems better to me. In this case I guess the good solid tabbing spreads the load nicely.

That's the idea. That's why the nice taper on the relatively wide tabbing (9"). There is no give in that G10 bulkhead whatsoever. None. I know for sure, because I accidentally shin kicked that sucker and have a permanent dent in my shinbone to show for it!
This entire arrangement is the spine of the boat after all. I'm fine with zero flex. I'm sure the owner will be too, as he stated early on that he always wondered why he couldn't get the rig tension to stay tuned, it was always slack eventually no matter what. Because the mast
was bending the floor of the shattered keel
sump and forcing the gap between ballast keel
and stub to get larger,effectively being driven through the bottom of the boat every time the rig was tensioned! Now he will be able to crank up the rig tension all he wants with no trouble. His race
crew will be pleased. I predict improved performance.
I never understood putting in a strip of flexible material between the bulkhead and hull and then glassing over it with structural tabbing, which is rigid, anyway. Silly. Only helps to prevent bulkhead print through in very lightly built boats, IMHO.
