The certification landscape for recreational sailing is a tangle of national systems, international conventions, and charter-company policies that do not always align. An RYA Day Skipper qualification, earned in the Solent over a rainy week in March, is accepted by a charter company in Lefkada but questioned by one in Sardinia. An American ASA 104 opens doors in the BVI but raises eyebrows in France. The ICC — the International Certificate of Competence — was designed to cut through this confusion, and mostly does, though its recognition is neither universal nor automatic. This guide sets out what each qualification involves, what it costs, and what it will actually get you at the charter desk.
The ICC: International Certificate of Competence
The ICC is not a teaching qualification but a recognition document — a certificate issued by a national authority confirming that the holder is competent to operate a pleasure vessel in foreign waters. It was established under a United Nations resolution (UNECE Resolution 40) and is recognised across most of Europe, though individual countries may impose additional requirements.
Who issues it: In the UK, the RYA issues the ICC on behalf of the government. In other countries, the national sailing authority or maritime administration issues it. US citizens can obtain an ICC through certain approved schools, though the process is less standardised.
What it covers: The ICC can be endorsed for sail, power, or both, and for inland waterways, coastal waters, or both. For charter sailing, you need the sail endorsement for coastal waters.
How to get it: If you already hold an RYA Day Skipper (practical) or higher, the RYA will issue an ICC on application — it is a paperwork exercise, currently costing around GBP 50. Without an existing qualification, you must pass an ICC assessment, which tests boat handling, navigation theory, rules of the road, and safety procedures. The assessment can typically be completed in a day.
Where it works: The ICC is widely accepted across the Mediterranean, including Greece, Croatia, Italy (with some caveats — Italy officially requires its own Patente Nautica for Italian residents), Turkey, France, and Spain. It is less relevant in the Caribbean and the Americas, where charter companies tend to accept national qualifications directly.
The RYA pathway: from Competent Crew to Yachtmaster
The Royal Yachting Association's qualification scheme is the most widely recognised in the charter industry, largely because the UK has historically produced a disproportionate share of the world's charter sailors.
Competent Crew (5 days practical): An introduction to sailing — you learn to crew a yacht competently but not to skipper one. Not sufficient for bareboat charter.
Day Skipper Theory (40 hours, often self-study or evening classes): Covers navigation, meteorology, tides, pilotage, and passage planning. A paper qualification that provides the theoretical foundation for the practical course.
Day Skipper Practical (5 days aboard a training yacht): The baseline qualification for bareboat charter. You learn to skipper a yacht safely in familiar waters by day. Most Mediterranean charter companies accept Day Skipper as sufficient for a bareboat handover.
Coastal Skipper (5 days practical, with theory prerequisite): Builds on Day Skipper with night sailing, more demanding passage planning, and crew management. Opens doors in more challenging charter areas and for larger vessels.
Yachtmaster Coastal / Offshore (examined by an independent examiner): Professional-grade qualifications. Yachtmaster Offshore is the gold standard for the recreational sailor and qualifies you to skipper almost any charter vessel anywhere in the world.
The ASA pathway: the American system
The American Sailing Association's certification scheme operates differently from the RYA's but achieves similar outcomes. ASA courses are modular and can be taken at schools across the United States and in some international locations.
ASA 101 (Basic Keelboat Sailing): Introductory course. Not sufficient for charter.
ASA 103 (Basic Coastal Cruising): Covers sailing in moderate conditions on a small cruising yacht. Some charter companies in the BVI and Caribbean accept this for smaller boats.
ASA 104 (Bareboat Cruising): The standard charter qualification for American sailors. Covers yacht handling, navigation, anchoring, and systems management on a 30-40ft yacht. Most BVI and Caribbean charter companies accept ASA 104 for bareboat charter. Mediterranean operators generally accept it, though some prefer to see ASA 106 as well.
ASA 106 (Advanced Coastal Cruising): Covers night sailing, heavy weather, and more demanding navigation. Required by some Mediterranean charter companies for larger vessels or challenging destinations.
ASA 114 (Cruising Catamaran): A specialised course for multihull sailing. Not universally required for catamaran charter but increasingly recommended by charter companies.
What charter companies actually require
The official requirements and the practical reality sometimes diverge. In general:
Greece: ICC or RYA Day Skipper is sufficient for most charter companies. ASA 104 is accepted by most operators. Some companies ask for a sailing CV in addition to the certificate.
Croatia: Similar to Greece. The ICC is officially required by Croatian maritime law, but in practice, an RYA Day Skipper or ASA 104 is accepted by most charter companies.
Italy: Officially requires a Patente Nautica (Italian boating licence) for vessels over 40 gross tonnes or for sailing more than 6 nautical miles from shore. In practice, the ICC or RYA Day Skipper is accepted by charter companies for standard bareboat yachts. Italy is the strictest Mediterranean country for paperwork.
Turkey: The most relaxed. Many charter companies accept a sailing CV and verbal demonstration of competence in lieu of formal certification. However, holding an ICC or RYA Day Skipper smooths the process considerably.
BVI and Caribbean: ASA 104 or RYA Day Skipper is the standard requirement. Many charter companies also accept a detailed sailing CV from experienced sailors without formal certification — particularly for repeat clients.
France: Officially recognises the ICC. French charter companies tend to be thorough in checking documentation but accept the standard European qualifications.
The practical advice
If you hold no qualification and want to charter a bareboat: take an RYA Day Skipper course (theory and practical, roughly two weeks total) if you are UK-based, or an ASA 104 course (typically 5-7 days) if US-based. Either will open most doors in most charter destinations.
If you already hold RYA Day Skipper or ASA 104: obtain an ICC if you plan to charter in the Mediterranean. The application is straightforward and the document removes friction at the charter desk.
If you have extensive experience but no formal qualifications: prepare a detailed sailing CV listing boats sailed, miles logged, destinations visited, and any informal training. Most charter companies will accept this, though a small number insist on paper certification regardless.
The honest advice is to over-qualify rather than under-qualify. The difference between Day Skipper and Coastal Skipper is a week's training and a few hundred pounds, but the confidence and competence it builds pays dividends every time you sail in unfamiliar waters.
