Hi Neil,
I'd like to thank you for your informative posting. This web-site is so educational!
I'm looking at the last four yachts that you have posted pics for us to see, and I only see one (Chevy Toy) that is flying the correct "Courtesy" flag.
I have to go way back to my US Navy days trying to remember proper flag protocols. If I am correct, the courtesy flag is always flown from the starboard-yard.
But, I am confused. It looks like all the pics you have posted show their "flag country" colors flying from their stern mast? I recall flying our country colors from the main mast while underway, and shifting them to the stern mast only after passing lines ashore, or dropping the "hook". Is my memory just too foggy, or are these vessels "jumping the gun" with their country colors?
