I'm working on a Great Lakes Bulk Carrier in Z scale. It's the SeaWay max 730 feet long by 75 feet beam--huge even for Z scale at about 40 inches long. The size might be apparent by the proverbial dime on the deck about amidship. Still lots of development to go, but notice that it features open holds. Of course, that means a lot of work for the coamings around the hatches. I need some indication of interest before I put this into production. I'm pretty sure that lack of demand for something this size will lead to it being an "on commission only" model.
