What is the offshore licence?

The offshore licence (extension of the coastal licence) permits navigation at sea with no distance limit from shore. It is the licence for navigators wishing to make crossings, sail at night, or venture into open seas and distant waters.

What are the conditions for the offshore licence?

To access offshore training, you must already hold the coastal licence. There is no specific age requirement, but practical navigation experience is strongly recommended. The training is technically and theoretically demanding.

The content of offshore training

Astronomical navigation

The offshore licence introduces astronomical navigation: use of the sextant, plotting position by celestial bodies (sun, stars), determining latitude and longitude. Even if GPS is ubiquitous, these techniques remain on the curriculum and are essential in the event of an electronic failure.

Advanced marine meteorology

The training deepens marine meteorology: reading fax weather charts, identifying weather systems, forecasting wind and waves, and how to behave in a storm.

Electronic navigation

The offshore licence covers the use of navigation GPS, electronic charts (ECDIS), radar and AIS (Automatic Identification System) for safe navigation.

What does the offshore licence cost?

Offshore training costs between €800 and €1,400. It includes theory lessons (generally 30 to 40 hours) and practice trips at sea. The theory test is a 3-hour written exam.
