For the history nerds. The Eisbach wave was the world's first river wave. And is the fastest still. The second was the one in Montreal, Habitat 67. 1998. Bigger, wider, but a real big river. And also too many people. Third was ours, 1999. Radetzky Graz, Austria. Bigger, higher, but was not running that often. But was officially recognized, and allowed. No police harassment as in Munich. Now destroyed by the local energy company.

We had to repair our wave every few years. Munich does it similarly. Many good waves are now destroyed, because the repair became troublesome. In Munich they already destroyed their 2nd wave, Flosslände, and the third, the best but deadly one directly in the river is forbidden. In Graz we had 5. Montreal also has more. Boisy is good. Swiss and French also have some.
