Under the Bavarian Water Act (BayWG), anyone may, in principle, use surface waters free of charge—including for navigating small, non-motorized vessels—without requiring official authorization or the consent of the waterway owner or other authorized parties. This includes small boats up to 9.20 meters in length without a motor, such as rowboats, paddleboats, inflatable boats, and sailboats without built-in living quarters, cooking facilities, or sanitary facilities, as well as windsurfers and kitesurfers. This so-called “public use” applies to activities within the scope of traditional forms of leisure and sports. These activities—in contrast to the right of access under nature conservation law—may serve both the enjoyment of nature and recreation, as well as primarily economic or exclusively sporting interests, such as in the case of competitions.
Sailboat
Sailing in sailboats 9.20 m or longer, or with an auxiliary engine exceeding 4 kW (5.5 PS) engine power or equipped with built-in living quarters, cooking facilities, or sanitary facilities is not covered by this generally permitted public use in Bavaria and therefore requires a navigation permit from the district administrative authority. A living quarters is defined as a structure enclosed on all sides with a clear height of more than 1.20 cm.
Motorboat
Permission may only be granted for boats that are no longer than 9.00 m and whose total permissible engine power does not exceed 191 kW (260 PS).
In addition, a Stage 1 exhaust emissions certificate in accordance with the Lake Constance Navigation Regulations must be submitted for the engine, or the exhaust emission limits of the Recreational Craft Directive must be complied with.
Sailboats cannot be registered as motorboats.
Special regulations apply to vintage boats.
Electric boat
If a boat hull (including an inflatable boat) is equipped with an electric motor, it is classified as an electric motorboat under the Bavarian Shipping Regulations (BaySchiffV). This requires a permit.
Vacation Permit
Vacationers may apply for a vacation permit for a sailboat or an electric motorboat once a year for a maximum of 4 weeks.
