Discharge chutes, for the heads.

I also have added the thin strips to the sides as shown in the 3rd pic below - anyone have any idea what these are supposed to be?

It's 100 years ago.
So to get rid of things like boiler ash and cinders from coal firing and kitchen scraps (before and after you've eaten), etc., without dirtying the side of your ship, you use hollow chutes to the waterline. Stuff the environment - you aren't into that yet.
Following this build with interest.

Aha - I see, makes sense.

Have applied the decks tonight - will try to take some pics tomorrow.
