I don't see any need to apologise. It is definitely the right of any government
to know who is in their territories, it is just the way it is done. The UK government,in future, expects everybody to be equipped with satellite
capable iPhones, so you can surf to their website in the middle of the bloody North Sea and register which port you are entering 24 hours later. And if the wind
changes in the meantime, you still have to enter the port you registered for. On top of this you can expect a warm British welcome from a bunch of robocops in boats, who will board, search and intimidate at will.
It'll be the hobnail boots of the Flying Squad, Special Branch or MI6 , I can hear at the door.
