There is no law or legalities involved. If it is your own private pleasure
craft than you can basically do what you like. Out of respect you may fly
the country you are in flag the highest then a nationality flag of those on
board is simple respect or courtesy. The numbers of the vessel must be
clearly visible and that will tell what country your registered in and
whether you fly flags or not it is up to you.

I think the international rules say that you fly the flag of the country
of registry (flag of convenience ?).

Is it improper (illegal) to instead fly the flag of the owner's
nationality as long as a courtesy flag is flown under the spreader ?

Related question; are there any maritime law web sites for future
reference ?

Thanks,
