The old Bastien-class liners were ideally suited to haul a mixture of VIPs and high value cargo considerable distances in a comparatively short time. There is very little demand for that sort of service in the Wilds, however. The Bastien-class liners carry less cargo than the workhorse Far Traders, while having significantly higher operation costs. The only advantage of the class is their ability to make 3-parsec jumps, and so the occasional survivors of the class usually ply either areas of low stellar density or make key trade connections between two mains separated by a 3 parsec jump connection.
