Confident on the Main: The most important SUP rules for Frankfurt

Experiencing the Frankfurt skyline from the water has its own appeal. For many, stand-up paddleboarding becomes a prime spot on the Main River. But what begins as a relaxed activity is subject to clear rules that hardly anyone knows. We've summarized what you need to know to stay confidently on course.

The SUP board is legally considered a small vessel and is therefore subject to inland waterway regulations. Check the conditions before setting off. Currents and commercial shipping on the Main require foresight. Beginners should therefore always stay close to the shore and only set off in calm weather.

Traffic rules on the water

Strict rules apply on the Main River. As a paddler, you must always give way to commercial vessels and sailboats. If two SUPs meet, the same rule applies as on land: right before left. In narrow passages or canals, there is a clear rule of right-hand navigation.

Don't underestimate the wave action caused by faster boats. Keep a sufficient distance to avoid losing your balance. Although private motorboats are legally required to give way, paddlers are often difficult to see. Anticipation is the best protection here.

Alcohol limits and taboo zones

This relaxed tour isn't compatible with alcohol. The blood alcohol limit on the water is 0.5. Anyone found paddling unsafely with a blood alcohol level of 0.3 is committing a criminal offense. The consequences range from hefty fines to criminal proceedings.

Certain zones are completely closed to paddlers. These include lock areas, designated swimming zones, and, above all, nature reserves designed to protect flora and fauna.

Safe on the road until sunset

Anyone who wants to enjoy the twilight on the Main River needs proper lighting. A white all-round light is mandatory in the dark to remain visible to others.

The standard equipment for every tour should also include three items that, although not required, are essential for safety: a mobile phone in a waterproof case, a leash that connects you to the board, and a small whistle for emergencies.
