What permissions/licences are required for yacht steering?
Permissions allowing to steer the same yacht in your country are also respected in other countries.
In Croatia, a SRC (Short Range Certificate) operator licence is also required. In general, it is not required in other countries, but you should complete a SRC course and have licence for your own safety.
In some water areas (like Greece), an additional person (so called co-skipper) with documented sailing experience is required apart from the skipper.
