Heroic work by all involved, but what the hell was the ship doing out there?
If as a commercial pilot I had done the equivalent I would have been lambasted. Dover, Felixtowe etc. were all shut, why were they out there putting themselves and others at risk. The weather was well forecast and certainly should not have caught anyone out.
Do they not have any kind of operational limits, if so they must surely have put to sea in excess of them.
Luckily noone was hurt.
