This Way Up
The This Way Up is a fringe merchant ship/tramp freighter/whatever-you-want-to-call-it. It's used as the ship (and title) for a set of convention games.
It probably converts best to a Fantasy merchant-ship (add a bunch of faceless crew to trim the rigging, etc.) or caravan-style traders (add more NPCs as guards and servants). I don't think it would do very well in Modern or Near Future, unfortunately.
