We ski without spotters regularly even though it is against the rules. There are rarely patrols on our lake and it is generally early morning or midweek when there is little to no competing boat traffic. In the last 15 years only once has one of our crowd been caught and it was a holiday weekend when he shouldn’t have been skiing without a spotter.
I do drive my son doing toes without a spotter or as the release person when my wife is in the boat. I use a Masterline Robbins release and put an extra section of rope and hold it with my foot. If he falls I can’t possibly hold him in.
