St. Martin FAQs

St. Martin is part of the French Antilles, which also includes Martinique, Guadeloupe, St. Barts and French Guiana. They all share the same clearance procedures, however, yachts must still complete outward and inward clearance when moving from one French island to another.

Pre-Arrival Boat: There is now an online clearance form to streamline the clearance procedure. This can be filled in prior to arrival with vessel and crew details, or, if getting online is not possible, on arrival in St. Martin. See Clearance for details.
Pre-Arrival Crew: A great number of countries do not need a visa. See Immigration for details.
Where can I enter? With the new online form it’s not necessary to enter at a port of entry. Click on the blue “Explore Country” button and then the anchor symbol to see the three official ports of entry.
Are fees high to enter by yacht? Just 5 Euros (or less) admin. charge – see Fees for details.
What security concerns should I know about? There was a recent (Dec 24) issue with a number of boat boardings and theft. See Security for more info.
