It is probably advisable to head for a main port first where it is possible to register entry. This involves customs inspecting passports and yacht registration papers. No formal entry papers are issued although registration documents must be carried. If foreign yachts stay in French waters for more than 6 months out of 12, import duties will become due. Another interesting point to note is that yachts cannot be loaned out without the skipper or owner being on board. Also, yachts registered in countries, which have not entered into special agreements with France, may be subject to additional duties. It is also worth noting that harbour and marina charges are higher in summer than at other times and that many harbours east of Toulon charge from noon-to-noon and not on a 24-hour time period from time of arrival.
