Agree wholeheartedly on proactively getting regulations put in place. On many stillwaters in the province we have speed restrictions, as well as fuel/motor-type restrictions.
Seems to me like a 10 km/h, electric motors only restriction on moving waters should do the trick.
To a non-jet boat/power boat guy like me, if a person wanted to take this sort of a jet boat out to rip around in, why not go to one of AB's numerous large lakes to do so? Seems a great deal safer to me.
