Just thinking!
I think in my Seventy Years of building just about everybody's large ship and boat releases, that under the different names I have built, modified and totally reconstructed at least ten of either the Robt.E.Lee and the Natchez. Sometimes scratch building a Stern wheeler from the hulls and cabin parts I could use.
I recently started gathering parts for another. This time, Just the Natchez. But! with a twist. I have cut out all the molded on/in windows and replaced them with model RailRoad parts from Tichy Train Group. Why them specificially? Well, can you say Quality? And high attention to the detail. When you take a double hung sash, It is molded to represent that type even the smaller ones. Doors too.
This is so much better than trying to clean up the very poorly molded on windows that just stick out way to far from the Bulkheads. Plus with P.V.C. Piping for the stacks, then you can use those Nice Brass crowns from Miniature Hurricane Lamps ( The little crown that holds the Glass Chimney in place.) They look better anyway. The P.V.C. pipes give you the option of using Model Sailing ships eyes for the support cables on them.
The deck has an edge that would be used for support as well as a stop to keep anything from Sliding overboard, because these are so tall I am replacing them with Plastic stripping, you can use skivved wood of your choice for decking. I am going to use some Card Thin Teak on mine. Nothing fancy on deck except the Crown Plank. That's the one that's three planks wide ,Dead Center of the deck!! One of the things the models lack(Both of Them) is proper deck support from the hull to the deck edge. Tichy can help here too. All you have to do is look for their Cast Iron Light Supports.
NOTE:
If you build one in any scale above 1/87 you better be able to do a lot of interior detail.The Wheel-Houses on those were pretty open for visual work by the crew. Had to watch out for snags( Floating Trees(Or Stuck Ones) that could rip a hole in the hull, and sink your vessel.
