HA! - Right, matey! Our boat flew a Jolly Roger always, and we were never fired upon. Course our boat was ~named~ the Jolly Roger!

No, lots of boats fly the skull and bones. But: if you raise the Universal Yacht Club Cocktail Pennant (a martini glass against a light blue field) they do have the right to board and get a beer.
