If I recall correctly, you can do some leisure travel around the Bodensee (Lake Constance) on one that is moored out of the historical harbor in Friedrichshafen. A friend who’s a pilot even logged training hours on one of them — just to check that off the bucket list. They can be seen circling the lake nearly every day in summer.
