From publisher blurb: The Moose is a Frontier transport, intended to connect worlds 9 light years apart in one jump. It is useful when looking for new markets and spends most if its time at starports with few facilities. It is not intended to be a warship, but can be fitted with turrets to defend itself. It carries 228 tons of cargo. You get A3 size deck plans, a description of the interior and design and a supplement called Between Decks. This discusses the ancillary systems that are necessary to make a ship work, but are not covered in the design rules. As such, Between Decks is intended to help the referee with ideas to help make the game more believable. It also includes a few ideas for scenarios.
