Ahoy mighty sailor!

Whether on the high seas or in the harbour – do you know the light and sound signals and the right of way rules? Seaproof prepares you for tests and actual seafaring.

We have compiled three packages of over 200 vessel lights, 50 basic and advanced sound signals and over 50 different right of way rules situations.

Check out what you can do with this app!
