Good points Rolf.
To tell the truth, I am constantly revising my repair plan as I go along. It all just started because I had a nice day without wind, so I decided to open her up. Then I glassed the crack. Then I decided that wouldn't work for long. So, I created a bulkhead out of a piece of scrap (which is one reason why it isn't full depth). Then I decided that one wasn't enough. Etc.

As it stands, I just wanted to laminate something across the crack failure in the side of the hull that also supported the crack failure in the deck.

Its not too late to tape the bulkheads in. I would guess that I would have bogged and filleted the bulkheads before taping anywise. It has been a possiblity that the the bulkeheads will "print" through the hull. Perhaps adding the tape will alleviate this.

And I do have the hole saw in my tool bag to create some holes. Thanks for the picture of your bulkheads.
