Stores and Equipment Aboard Wanderer
From Wanderer's database, and what is available at home, the Imperium had advanced to Jump 6 at their highest tech level (TL-15 in the game). Naval vessels, X-boats, fast passenger liners, and couriers were among those ships that could jump that far. So, they weren't altogether rare, but they were usually only for governments or corporations, since they couldn't carry much cargo for their displacement tonnage.
I'm using TNE rules, so it will allow for some really small jump-capable ships. This is the smallest one I could engineer at TL-15.
At TL-21, it's possible to make a jump-capable spacesuit with an antimatter power source. I don't know that I'd want to spend a week going potty in a spacesuit, but it's possible ;-)
