I really don't think that is a safe idea. Nor is the online course.
When I took the on-hands course, I love the way the instructor took us outside and show us what is 150 ft!. That should be a mandatory part of the safety course. There are too many infractions of the 150' rule!
I'm tired of seeing the rental boats/jetskis violating the 150', no wake, and or ROW rules. Seems like the MPs are tied up with chasing the renters down.
