Nothing works on our waters without signs and buoys. But which sign restricts a water area, which sign allows me to surf, and what does the light signal at the lock of the North Sea-Baltic Sea Canal mean? This board provides an overview of the most important lateral, cardinal, and special signs, as well as structure lights and additional signs. The board is also resistant to the harsh conditions of daily life on board and should not be missing from any helm station. It is ideally suited for preparing for one of the official boating licenses (SBF Inland or SBF Sea). With this double-sided, laminated information board, even beginners can quickly and safely navigate on the water.
