Here is presented a nice neat vessel that seems custom-designed for a group of player-characters roaming the black in search of adventure.
The Lune Class Freelancer is indeed designed for small groups of people for whom mobility is important. It's Jump 3 and has a small amount of cargo space; probably better as a courier than as a trader.
What is rather nice is a selection of 'well-known' vessels of this class, complete with illustration (showing the external colourscheme - mostly very colourful) and brief description of what that particular ship's owners have done with it - one's a casino, with the cargo bay tricked out for gaming, another belongs to a pirate band and has a 'breaching airlock' fitted, several have been converted to troop carrying and so on. Several of these variants feature in the collection of 'starship record sheets' provided at the end of the work.
There's also a nice guided tour, a verbal discription of what you'd see were someone to show you round a Lune Class. That gives a nice feel for the ship, and can be used in conjunction with the deckplans to describe it to the party.
After several external views and the deckplans, also a nice picture of one sitting on the ground at a starport, there's a complete rundown of the history and current crew of the Lune Star, as an example of one in service. More deckplans - including several of the common variant configurations - and even full details of the standard launch (and variants) make this a complete introduction to a very useful starship.
