A 64 footer, yow! that's a big one. I would guess you're not single
handing that one!
You are sailing in good waters until you get out of the Eastern Mediterranean
. After that be warry of unwelcome guests that approach too close. If there are plenty of you and you are in a convoy of some sort you should be ok, but Arab countries are funny
about a few things - women should have hijabs, exc. An additional piece of advice is never eat with your left hand, Arabs find that offensive. Be careful about talking politics or religion, the police in those countries are often plain clothed and consider 'wrong thought' to be a crime.
Welcome to the forum and good luck with your trip.
