From Berkeley site:
Berkeley kept setting new records for jets below the 100 mph mark until Phil Younger at the wheel of the "Menace", basically a Wreidt hull, was clocked at 104.77 mph at Whiskey Creek, California, in June, 1970.

Someone here must have information about Phil or the Menace. I searched the net but came up empty. That is a cool claim to fame for us stepchild Wreidt owners. Moreover, solid jet boat history. I am surprised there isn't a shrine somewhere.
