very surprised I guess, that a courtesy flag would go above your own countries flag.
Don't know that these are "rules" for pleasure vessels so much as they are guidelines and customs.
Although the courtesy flag on a spreader is technically higher in elevation than one's own country flag, the flag of origin is flown from the position of highest honor, typically the stern of a sailboat.
These things are spelled out on the US Power Squadron web site as well as other places around the net.
I think most of the customs go back to the British Navy's early days.
