Mystery of the on-time Ferry

I had an interesting ferry Journey from Rotterdam to Hull on Thursday night. The ferry normally leaves Rotterdam at 9pm and get to Hull at 7am the next morning
When I arrived at the Ferry terminal the winds were blowing at 30mph and it was beginning to rain heavily.
About 30 minutes after arriving all passengers were handed a handed a letter from PandO staff:

• Due to the high winds the Ferry needed tug assistance to turn around in harbour.
• However the Port of Rotterdam Tug company was on strike for 24 hrs so no tug would be available until 0430 the next morning.
• The ferry would therefore leave at 0430 and get to Hull at 1500.

Some people were very upset, but most (who were British) trooped onto the Ferry anyway at the normal time 1700 onwards. The main conversation was around whether there would enough beer on the Ferry for a 22 hour trip and would lunch on Friday be free ?

In one of the shops at 1830, the staff explained that they had heard the captain was making a decision at 2130 whether he would try and turn around in the harbour or wait for a tug the next morning.

However Captain Tyson is a Hull man, and one should never keep a Hull captain from his breakfast in Hull. At 21.04 he comes on the loudspeakers saying, he was going to the Ferry around under its own power and we should be in Hull in the morning.

With a careful turn-around of we headed into the North Sea, for what was a fairly rough crossing, subdued in my case by copious amounts of red wine !

When I awoke at 7am we were in Hull - I wondered how many people cancelled holidays, Business trips or visits........just because the letter of PandO published 14 hours earlier ?
