Stop-by-step been making a little progress. Didn't have time with the "real job" (or maybe that should just be the "paying job") this week, but did finish a lot of the head (bathroom) walls and doorway.

I had the side wall on for a while, but finally got the forward wall cut to shape and in place. It was a little trickier since it had to follow the cabin and hull sidewall profile. Not perfect, but with a little caulk it will be fine. Its not structural anyhow, just something to give some privacy.

As is apparent in the picture, I pieced the wall out of various scrap 1/8" ply I had around, thus it doesn't match at all. It will all be painted and should be ok.

I had discussed with underwhelming response just having a curtain on the head instead of a true door. That seemed unacceptable to the family, and it was pointed out that it wouldn't work great if we plumbed for a shower, so I went ahead and built a hard door. Don't have it hung yet, but its about ready. Nothing fancy, just a simple frame with skin.
