In that case you'll probably cope fine. The carpentry is only 25% of the story. All bulkhead building involves repairing the floor finish (both sides), repairing the deckhead (ceiling) finish where the removed bulkhead was, and same for the cabin side finish. Also lighting and switching can be affected, and windows get in the way. In addition nearly every bulkhead worth moving involves the galley and/or the shower room!
And often a door....
Nothing is EVER simple where boat alterations are concerned.
Forgot to say, bear in mind all work on boats takes three times as long as your worst estimate, and costs three times as much.
Hope that helps, lol!
