Mike,
They have a number of portys onboard to do the areas that are too small for us to do.
I also do the C&U training for the fleet and so I am off to Dubrovnik of Friday to meet a ship, train up some of the crew for three days and then travel back from Athens. The week after that it's off to Rome and back from Barcelona. Well, some poor sod has to do it, might as well be me!!
