They railings still exist; I've simply hidden them to reduce clutter for the viewing experience. They have not changed. Also, I am far more busy with real life, so this has taken a very far back seat. Most of what has changed is lore-related and specifications more than the model itself. They will be given in an attachment.
Now, visually, what has changed? Let's stop from the top; quite literally at that.
As you can see, the funnels are much less wide than they used to be and are also farther forward. #5's causing will be repurposed for passenger amenities and features. #3 is technically the tallest funnel as it travels through the break in Boat Deck's Superstructure vertically (Obscured by Sun Deck from this angle) before sweeping back with the others.
Rudder iteration #3. This one is the same height as the previous model, however, it is shorter with a bit of a counter-balance to it Honestly, this design is far more interesting, and would not cause as dramatic a turning circle when put hard-over in either direction.Default character model is there for scale. I need to make those geometries on the props hidden, but that can wait a while yet. I've also made the core of the rudder thicker and far more visible than it was previously being about 1m in diameter. (Rudder is 0.8m thick of solid steel)
Overall, I was inspired to do more work on this project thanks to another project in the making about the RMS Titanic where they are recreating the ship in virtual reality down to every last rivet, fixture and carving. I'm not sure if it would count as advertising or not, so I am not going to say the name of this in-development game at this time. Attached, you can find a brief stat and lore write-up I have done on the Zelda. Subject to change, of course.
