The ICC (International Certificate of Competence) Explained

Published · Last checked October 2026

The International Certificate of Competence (ICC) is evidence that you can skipper a pleasure boat, accepted in many European countries under UNECE Resolution 40. UK residents usually get it from the RYA, either by holding a qualifying practical certificate such as Day Skipper practical or by passing an ICC assessment at an RYA training centre. Charter companies in Europe commonly ask for it.

Who needs one

  • Skippers chartering in many European countries, where companies or local authorities ask for proof of competence.
  • Owners cruising in some countries' waters, especially inland waterways.
  • The UK does not require a licence for leisure sailing at home, but the ICC is what other countries recognise.

How to get it (UK)

Flow chart: by course or by assessment, then apply to the RYA to get the ICC, plus a CEVNI test for the inland endorsement
The two routes to an ICC for UK residents.
  1. By course: an RYA practical certificate such as Day Skipper (sail or power) or Powerboat Level 2 qualifies you to apply.
  2. By assessment: an experienced sailor without a course certificate can take an ICC assessment at an RYA training centre.
  3. Apply to the RYA with your certificate and photograph. Check eligibility, as it depends on nationality and residence.

Inland waterways and CEVNI

For European inland waterways, the ICC needs an inland endorsement, which requires passing a CEVNI test on the European inland waterway rules.
