Is that a US rule (or guideline)?

If it is a US - Rule, my goodness, what does that mean to the rest of

Anyway, in Europe it is a custom to fly a courtesy flag from the
starboard spreader also. There is no other rule but the esthetic
virtues of the skipper to establish the correct measurement in
relation to the size of the vessel. I believe courtesy flags come in 2
sizes tops.
