Interesting stuff L,
Never knew there was a ship of the USN authorized to fly the Skull and Crossbones. Growing up I had learned that it was considered a symbol of armed aggression by privateers, but may be those were just old wives tales.
I have never understood seeing pleasure boaters flying it. To me it's like a weekend warrior Harley rider putting a 1%er patch on his HOG vest. Not cool.
Oh well, I learned something new again today.
