Are you planning a cruise to Jersey and Guernsey aboard a sailboat? Whether you own your own boat or rent a sailboat in Brittany, a trip to the Channel Islands promises a change of scenery and a little adventure at sea. Although these islands are only a few miles off the French coast, they are not part of the European Union. And when you cross a border, you have to comply with formalities.
Dans cet article, nous vous proposons un récapitulatif clair et à jour (informations d’AVRIL 2026) des démarches nécessaires avant d’appareiller pour Jersey, les Minquiers, les Écréhous ou Guernesey, Serq, Aurigny ou Herm. Un point essentiel pour naviguer en règle et l’esprit tranquille !
Please note: Jersey and Guernsey have two different administrative formalities for entering their territories.
NOUVEAU 2026 : ETA et passeports obligatoires pour toutes les croisières vers Jersey et Guernesey
A partir d’avril 2026, les îles anglo-normandes rejoignent la démarche du Royaume-Unis et imposent un ETA (Electronic Travel Authorization) à toutes les personnes se rendant à Jersey ou Guernesey en voilier. Cela vaut que vous partiez avec votre propre bateau ou dans le cadre d’une location de voilier depuis la Bretagne nord.
Toujours obligatoire, le passeport pour tous les membres de l’équipage, sans exception. Une carte d’identité ne suffit plus depuis le Brexit.
Ne pas confondre avec la possibilité de présenter uniquement une carte d’identité en cours de validité (pas de reconduction 5 ans) qui était accepté uniquement dans le cadre d’un aller-retour en ferry sur moins de 24 heures. Cette dérogation était valable jusqu’en décembre 2025.
ATTENTION : il y a beaucoup de sites internet pirates qui vendent aussi des ETA. Ils peuvent fonctionner, mais vous paierez plus cher. Le coût officiel est de 20 £. Le gouvernement britannique vous recommande d’utiliser l’application mobile afin de pouvoir scanner plus facilement votre passeport.
Le site internet officiel pour la demande d’ETA pour Jersey, Guernesey et l’Angleterre est le suivant : https://apply-for-an-eta.homeoffice.gov.uk/apply/electronic-travel-authorisation/easier-on-the-app
La demande d’ETA pour tout l’équipage n’exclut pas l’enregistrement du bateau avant votre arrivée. Veuillez consulter les modalités ci-dessous.
Sailing to Jersey or its dependencies (Ecréhous, Minquiers)
Jersey has set up a simple and efficient online declaration system. All you need to do is fill in a form at least 24 hours before your arrival, mentioning :
- Your sailing intentions (port of departure, port of arrival, date, time...)
- Information about the boat (type, length, registration, home port, etc.)
- Crew list
- Skipper's contact details
Access the customs and immigration form for Jersey.
Please note: this form is required even if you don't intend to dock in Jersey, but simply anchor at Écréhous or Les Minquiers.
Guernsey, Herm, Sark and Alderney: different entry systems
The Bailiwick of Guernsey has its own system. Here, no online declaration is required. On arrival, you must :
- Hoist flag Q (yellow flag) as soon as you enter Bailliage waters.
- Fill in form GC27, available online or sometimes supplied at the port.
- Deposit the white copy of the form in an official letterbox, often yellow, located in validated ports (such as St Peter Port or Braye - or directly at the harbor master's office during opening hours).
- Keep the pink copy on board, in case of inspection.
- Display the Q flag once the form has been submitted.
Download customs form GC27 and print it out in duplicate.
⚠️ Important: it is forbidden to disembark directly at Herm or Sercq/Sark without first passing through a validated port (and completing the declaration). Be sure to plan ahead.
Whether you're renting or cruising for yourself, plan your vacation to the Channel Islands in advance.
If you're planning a cruise to Jersey and Guernsey, be sure to inform your charter company of your plans to sail to the Channel Islands. He'll make sure you have the necessary charts on board (electronic cartography is always on board) and the Q flag if you're sailing to Guernsey.
At Loc Voile Armor, we regularly accompany customers to the Channel Islands. Whether you're a seasoned skipper or a one-off skipper, we'll help you choose a suitable sailboat and prepare the documentation.
