some of the beer can boats that bounce off rocks on the Yuba river are reputed to be 100 mph jets. There was an aussy through here last year with a Twin turbo big block chevy that was advertized as a 115 mph boat. I placed myself and a chippy friend at the end of roughly 1/4 mile of smooth deep water and he was only doing 71. There used to be lots of 100 mph jets, but that was before GPS and radar guns. buuuuut its an interesting goal for bench racing
