Kurt,
Now THAT'S a great idea - opening up the top. Keeps spaciousness, disapates odors. Could soft screen the top, along with the doorway - and it solves the bulkhead over the deadlite issue. If it is an issue: I've seen this work in pics of other boats if the bulkhead is NOT made an issue. If it is designed so that the critical eye sees the solution as, say, providing light to an 'enclosed' space and also providing an open feeling to the accomadation, then there is nothing 'wrong' with it. If the bulkhead was structural, it couldn't work. But as 'furniture', if it can be called that, it's fine!

Another thought: If you step the foreandaft companionway bulkhead (instead of adding cleats and steps to a sheer surface) you could created more room inside the head. Especially knee-room! What I mean is that you could make one side of the comp. ladder with a wall that is stepped out with ledges that are actually space makers inside the head. Maybe just one step could be done that way with the wall. NO?
