The International Certificate of Competence (ICC) is required by most European countries as evidence of a basic level of competence and often required to hire a yacht abroad.
Member states are not obliged to accept the ICC however it is normally widely recognised. It can not be issued to nationals of UNECE Member countries unless they are Nationals or Residents of the UK or The Netherlands. See here for a full list of UNECE countries whose citizens are NOT able to apply for an ICC issued by the RYA.
Within the RYA scheme the level of competence falls just below the level of Day Skipper practical. Holders of the RYA Day Skipper (Power or Sail) can apply for the ICC without any further tests. Simply complete the ICC form.
To receive an ICC, candidates are required to prove competency in handling a boat with sufficient knowledge of navigation procedures, pilotage, safety procedures and the International Regulations for the prevention of collisions at sea. The examination can be taken on either a powerboat or sailboat depending on the endorsement required and usually takes about 4-6 hours.
The full tests can be done during evening classes, week days or weekends.
