Here's my take on the Nebula class. This is a representation of the "typical" Nebula class and thus has no particular traits assigned to it. It's also interesting in that it had 89 space, and used it all first time I've had a ship come out even.
PRODUCTION DATA

Class and Type: Nebula-class Exploratory Cruiser
Year Launched: 2357
HULL DATA
Structure: 35
Size/Decks: 7/28
Length/Beam/Height: 442.3/318.11/130.43

PROPULSION DATA

*this does not match previously published stats but is the closest I could come with the systems in the NG.
TACTICAL DATA

Traits: None**
** one idea I had was to sacrifice 5 structure for 5 extra space and use that to purchase "Hardened System (Sensors)".
Comments, corrections etc are most welcome.
