I am British resident in France with a boat registered in France. I have a "passeport" as opposed to an "Acte de Francisation" which means that I pay the same taxes as an French person.

As a resident non-French person I am not allowed to have an "acte de francisation" and therefore I was not allowed to wear the French flag. There now appears to reign a certain confusion in this area. I have been warned several times during custom's checks that I should have a French flag but on checking with Customs' representatives at the Salon Nautique they confirm that my continuing to wear the Red Ensign is correct.

Some custom's men then said that I should be registered in the UK. I said that no way was I going to register in two countries. They never followed up.
