The answer is straightforward: it’s not required. The sailing license you typically hear about applies only to sailboat rentals in certain regions (e.g., the Mediterranean, Seychelles, etc.). All sailboat rental companies are required by local port authorities to ensure that renters possess a sailing license before chartering.

However, if you own your sailboat, you are"technically" free to sail the world.

Yet—it’s well-known that local maritime authorities don’t always adhere to"higher-level" rules, and some jurisdictions have their own sailing license requirements. Usually, no one argues with them. Would you want to debate a foreign port authority that has already impounded your vessel? While unlikely to happen to you, such cases have occurred. For example, if you accidentally collide with another boat at a marina—accidents happen—and an investigation reveals you lack the proper license, you could face serious legal trouble abroad, including potential lawsuits.

Thus, obtaining a sailing license is wise for global cruising to avoid issues related to this topic.

What is the ICC? Sailing in Europe?

You need a sailing license, not just a certification. The International Certificate of Competence (ICC) is one accepted credential.

Though termed a"certificate," the ICC is effectively a license, defined by United Nations Resolution 40, adopted by 22 European member states. Many non-signatory countries also require the ICC via local maritime laws. In some nations, other licenses may be accepted, but users risk rejection by port authorities.

Why Do You Need the ICC (Sailing License)?

Sailing is inherently international. While navigating, you’ll interact with shipping lanes, vessels governed by international maritime law, lighthouses, lights, buoys, etc. Key regulations include the International Regulations for Preventing Collisions at Sea (COLREGs) and the *IALA-A/IALA-B* systems for lights and buoys. As a recreational sailor, you must comply with these rules, whether you understand them or not. Remarkably, many nations collaborated to establish minimum educational standards for sailors in their waters—later adopted by the UN to extend these standards globally. A brilliant idea, deserving credit to the diplomats and advocates behind it!

What Are the Requirements for the ICC?

You must demonstrate competence in:

Collision regulations

Navigation techniques

Maritime safety and survival

Understanding lights and buoys

Meteorology, tides, and currents

General seamanship

Both theoretical knowledge and practical skills are assessed.

How to Obtain the ICC (International Sailing License)?

There are two primary pathways, available only through approved ICC-issuing training centers:

One-Day Assessment: An intensive on-water evaluation with no instruction. The assessor will test theoretical knowledge and demand practical demonstrations in all required areas. If you cannot swiftly calculate courses, plot routes, determine tidal heights/currents, or answer questions on daymarks, cardinal marks, lighthouses, etc., you may fail. Mastery of theory is essential—complete the RYA Day Skipper course beforehand.

RYA Day Skipper Certification: A five-day on-water training program with extensive theory. Complete the RYA Day Skipper online theory course prior to practical training. Upon demonstrating competency, you’ll receive the RYA Day Skipper Certificate, which automatically qualifies you for the ICC.
