If you hold an EU or EEA passport and skipper in Croatia as a freelancer, you are required to notify the Croatian authorities before your first job, and again every year. Most skippers have never heard of this. It is free, it takes an afternoon, and they cannot refuse it.
Why it applies to you
Commanding a vessel is a regulated profession in Croatia because it concerns public safety. That brings you under the Act on Regulated Professions and Recognition of Foreign Professional Qualifications, which implements the EU professional qualifications rules.
Under that Act, a professional established in another EEA state who provides services in Croatia on a temporary and occasional basis must submit a prior written declaration before providing the service for the first time.
It is a notification, not an application. You are exercising a treaty right under the EU Services Directive, so provided your documents are valid there is nothing to approve. But the obligation to tell them is real.
It renews every year
The Act requires it to be filed "for each year in which the person intends to provide temporary or occasional services in the Republic of Croatia". It runs per calendar year, not twelve months from filing, so coming back next summer means filing again.
What to send, and where
Copy of your EU or EEA ID card or passport
Proof you are legally established at home (trade register extract, tax registration, or chamber of commerce certificate)
Copy of your skipper or Yachtmaster licence, which must be one Croatia recognises
Proof you are not banned or suspended from practising, if applicable
Send to the Ministry of the Sea, Transport and Infrastructure, Maritime Safety Directorate: verification@pomorstvo.hr, copying info@mmpi.hr. Scans are fine, Croatian or English.
Ask for confirmation of receipt and keep it with your ship's papers. The value of the declaration is being able to produce it.
If this is not you
Croatian nationals: register an obrt or company instead. Commercial tourism services must come from a registered business.
Employed by an EU company: your employer files a posting declaration with the Croatian State Inspectorate, not you.
Non-EU (UK, South Africa, Australia, US): you need a residence and work permit. Being a contractor does not avoid it.
