I'm considering a Z scale modern container ship for my next project. This would be in the "feeder" ship category, not one of the monsters. Right now I have an N scale ship of 60' beam that can be anywhere between 350' to 550' long. Since I'm going to have to cast a new bow and stern for the project, I'd like some input about what Z scalers really want. I could do a new ship of between 500' to 600' long, with a beam of 90', or a smaller ship of perhaps 300'-350' with a 45' beam. Any input will be appreciated.
