C'227,
Nice to see those two compared in drawings with each other like that. Thanks.
You are correct on all points.
I've gone on about this subject adnauseum elsewhere. But suffice to say that in the Ariel the bulkhead is part of the mast support system. There are the two posts that define the doorway - they go down to the hull above the turn of the bilge (screwed to the plywood bulkhead.)
There are two cross braces on the Vberth side also screwed to the bulkhead that terminate on the Vberth plywood tops. And two more vertical braces that support the end of compression beam at the coachroof sides - also terminating on the Vberth. Across the top the compression beam is also screwed to the bulkhead. And held in place thru the top by two bronze #14s or #16s coming thru the mast pad, thru the composite deck, and into the beam.* All structural wood was white oak.
The plywood bulkhead in A338 is really two halves with a filler across the top of the doorway and a filler across at the step up into the V-berth stateroom. There is no work done by either of these fillers. (FYI A338 has since been remodeled to remove the doorway.)
The plywood "bulkhead" is tabbed to the hull ONLY
and not to the under deck or the coachroof sides or overhead.
Only the hull. And not across where one might expect a 'floor' to be in a wood boat - per your question.
Originally the space between the bulkhead and the liner was stuffed with a factory supplied fabric covered foam tape.
The compression beam load is ultimately taken to the hull via the half bulkheads (let's call them) on either side of the doorway. The compression beam is not supported in the center between the door posts. The door posts therefore are dual compression posts if you look at it that way. But they bear on the hull incidentally. In an upgrade a wider bearing pad would be cut in under these posts.

*ANY upgrade or remodel imco, if you are working from the original Pearson model,
should have all dimensional wood members GLUED and screwed to the plywood at the very least.
But the Pearson model is very flawed.
