When we first cruised in the
Med almost two decades ago, we had wintered in
Barcelona and in Porto Di Roma ( Ostia). After almost two years in the EU, my wife, a Japanese national, needed to fly back home and we were both concerned that having overstayed the 90 day Schengen limit, she may have problems with immigration on the way out. There is a seaman's waver on that limit though for ship's crew, I believe, and in that belief I made a trip to the Canadian embassy in Rome ( my
boat was Canadian registered) and asked them to stamp a simple letter of intention stating that my wife was permanent crew and that she would be departing EU territory by
boat. I singed this letter as
captain and owner. Not surprisingly, when departing EU territory in Helsinki ( flight was Rome-Helsinki-Tokyo) she was questioned on her overstay in the EU to which she answered she was ship's crew and showed the immigration officer a copy of the ship's
registration as well as the letter I had written and had stamped by the Canadian embassy. The officer took a look at the documentation and waved her through without any problems.
Point of the story: (1)the problem with overstaying will probably only come up when you are flying out and, (2) even though this was almost 20 years ago when things were certainly a lot looser, a letter of some sort, preferably officially stamped, stating that you are permanent ship's crew might still
work in a pinch.
