Licensing
Depending on the country, boating on coastal waters and inland waters may require a license. Usually, commercially boating on coastal waters almost always requires a license, while recreational boating on coastal waters only requires a license when a certain boat size is exceeded (e.g. a length of 20 meters), or when passenger ships, ferries or tugboats are steered. Boating on international waters does not require any license, due to the absence of any laws or restrictions in this area. Some of the member states of the United Nations Economic Commission for Europe issues the International Certificate of Competence.
