In Ontario we now require boat licences for anything under 4 meters (ie. jet skis) for now ,by 2009 all boat drivers must have a licence to drive any boat.
I took the course on the internet, took me about 45 minutes,
as far as i'm concerned if you have to have a licence you should have to take a full day's course in the class and then a full day's course on the water.
It wouldn't stop stupid accidents like the picture but would at least give first time boaters the basics about water safety before they bring their families out on the water with no idea about water safety.
just a thought!
