Lake Constance, Obersee: how the place works
The Obersee lies between the Alps and the foothills, and both send wind. The föhn from the south reaches storm force in gusts under a blue sky; summer thunderstorms from the west build in twenty minutes. The storm warning given by the orange flashing lights is binding and counts as official.
Lake Constance, Obersee: what breaks there
Capsizes and flooding in dinghies and open boats, damage at mooring buoys and in the tight harbours. The lake is deep, salvage means a diver and a crane, and that turns even a small case expensive.
Lake Constance, Obersee: what this means for your policy
The Lake Constance navigation rules require you to make for the nearest harbour when a storm warning is given. Anyone leaving despite the warning will be arguing about the duty in a claim. Also check whether salvage costs are insured separately and at a sufficient level.
