The Jetski thing is oldhat ... even in high school on the Willamette, guys used to troll on Jetskis around Sellwood quite frequently. Typically, when they hooked up, they let the jet ski float and boarded another boat for a net job ... then the boat would run them back to their PWC. Used to see barges trolling as well, but I imagine they were always going way too fast to ever catch anything.
