Well, if they used the '77 rules (and the '81 edition wasn't out when
the X-boat first appears) they get to use a model/1bis rather than a
model/4 computer, saving 3 tons. Also in the '77 edition you do not have
to have a power plant if there's no manoeuvre drive (B2, p.13 only
mentions having to match the size of the manoeuvre drive). With 10 days
power fuel there's plenty of room for a couple of people, some cargo,
and the data banks, given that the last are whatever size the referee likes.

The rules in the '81 edition make things much harder and require house
rules on the power plant, etc. Book5, 1st edition makes it fairly easy,
even with a power plant - there's certainly room for a manoeuvre drive.
B5, 2nd edition isn't quite as generous (power plants are bigger when
under TL15), but still has lots of free space.

I can't be bothered checking out MT or TNE, but I'd be surprised if they
didn't have free space too.
