When I was tracking the boats, often there was nothing scheduled for the next few days then all of a sudden one would appear.
It was probably run by the same computer allocating VW's Golfs

5a: in transit:left the factory - on it's way to Emden.
5b: in transit:shipping - at Emden waiting a boat. Normally received 48 hours after 5a.
5c: in transit:nearly here - on boat to either Grimsby, Tyne or Sheerness depending on dealer location. At this stage VW can give you the name of the boat, but it sometimes skips this stage. Now states 10 days to dealer.
6. Arrived in the UK - as stated, takes up to 10 days apparently, although they try and do it within 7.
7. At dealer - just needs PDI and valet and is ready for you.
