When you start researching the German boating license, you’ll quickly hit the key question: inland (Binnen) or coastal (See)? Both licenses cover motorboats – but on different waters. Here’s everything you need to decide.

What does each license cover?

SBF Inland (Binnen)

Valid on all German inland waterways – rivers, canals, and lakes officially classified as federal waterways:

  • Rhine, Elbe, Mosel, Danube, Weser
  • Havel, Spree, Müritz, Chiemsee
  • Nord-Ostsee-Kanal, Elbe-Lübeck-Kanal

Best for: Houseboat trips in Germany, river cruising, lakes in Brandenburg or Bavaria.

SBF Coastal (See)

Valid on German coastal waterways and coastal waters internationally:

  • North Sea: Wadden Sea, Helgoland
  • Baltic Sea: Kiel Fjord, Rügen, Usedom
  • International: Croatian coast, Greek islands, Mallorca

Best for: Coastal sailing holidays, chartering boats in Mediterranean or Baltic destinations.

Important: The two licenses do not substitute for each other. SBF Inland only covers inland waterways; SBF Coastal only covers coastal waters.

Exam differences

Key topicsWaterway rules, light signals, sound signalsChart navigation, compass work, tidal calculations
Practical examYesYes (on coastal waters)

The key difference: SBF Coastal includes a written navigation task – you plot courses on a nautical chart and work with compass bearings. This makes the coastal exam significantly more demanding than the inland exam.

The combination tip

If you want both licenses long-term: do them together. A combined exam costs only ~€179 in exam fees instead of ~€279 (€131 + €148) separately – saving €100 on the exam fee alone.

Most instructors recommend starting with SBF Coastal (harder), then the inland exam becomes much easier – because the 72 base questions that appear in both exams are already well-practiced.

Which should you get?

Only planning to boat on German inland waterways? → SBF Inland is sufficient

Planning coastal holidays in Croatia, Greece, or the Baltic? → SBF Coastal

Want flexibility for both? → Combined exam saves money and preparation time

Still unsure? → Start with SBF Inland (cheaper, easier) and add coastal later

Summary

The key difference is coverage: inland for German rivers and lakes, coastal for sea and international waters. Anyone planning to boat flexibly long-term should consider the combined exam – it’s cheaper than taking them separately.
