I have also added another ship, an Inter-system Ferry, based on the Anaconda.
The other day I came across a liner that was parked in front of a station and exchanging shuttles with the station.
Off-topic trivia story: a few years ago on a cruise ship in the Western Med, after the shore excursions they couldn't get one of the winches working to retrieve one of the launches. We had to sit there in the bay for about 4 hours while two crew members were 'stranded' in this launch. After half an hour of bobbing about they were either authorised - or through their own initiative - decided to put the launch through its paces. They spent the next 2 hours belting round the bay, spinning it, slamming it from full ahead into reverse, zooming round the cruise ship and generally had a whale of a time showing off.
I think they must have been told off in the end; they spent their last hour creeping round the edge of the bay exploring caves and buoys.
(Some people moaned about the winch failing - these launches are also lifeboats. We explained the benefit of using the lifeboats as launches means they get tested every day or two so any faults get found and fixed very quickly. Also, the crew become expert in their handling: this was why we assumed they were allowed to 'play' for a while.)
