Security levels and warning notes
The German Federal Ministry of the Interior (BMI) publishes periodically information on sea areas and traffic routes threatened by piracy or other hazards. These include up to date information on hazards and security levels as well as recommendations for behavior in these sea areas.
You can find current security levels and warning notes on the website of the federal police. The individual warning notes of the Federal Ministry of the Interior (Bundesministerium des Innern, BMI) are available (with a click on the map) in German and English.
