Floorplan:

Here's the floor plan I'm working from. Although I am a computer guy by vocation, I find the process of drawing and planning on paper to be much more enjoyable then CAD work, especially for a one-off drawing like this.

At the rear is the Master Bedroom that will hold a full-sized bed oriented side-to-side. The wall of this room is framed with 2x8s to allow for some shelving and storage within.

The next room is the Bunk Room. It will have two bunk beds against the larboard side and a small table and 4 seats against the starboard. The seats are the rear buckets from a 1990 Olds Silhouette minivan. The backs of these seats fold flat and there will be brackets on the wall to allow the temporary installation of two additional bunks.

The galley is along the starboard side opposite the bathroom.

The Salon is up front, with a dinette against the starboard side. I haven't quite worked out the larboard side of the salon. I think the wood stove will go in the corner with the bathroom and there will likely be a chair and some shelves and a cabinet
