Erewon class

The Erewon-class was a type of transport vessel used by the United Federation of Planets during the 24th century. These ships were about four times larger than a runabout. 

In 2385, Brian Mallory traveled on an Erewon-class vessel, the SS New Horizon, from Deep Space 3 to the Obsidian Colony on Providence. (Obsidian Colony (PBEM))
