FWIW, the stories on this Web site appear to be fictional. I just read the lengthy https://www.stimmel-law.com/en/articles/story-13-adverse-pos... which is about a retired machinist engaging in boat jousts on Shaw Lake in Golden Gate Park. There's no trace of a real person named Benjamin McIsserson, and no Shaw Lake in Golden Gate Park. (It's probably a stand-in for Spreckels Lake, which was built for model boats but which has never hosted combat between them.)
So take it with a grain of salt.
