If we take the Laser Funboat as an example (much as I hate the damn things) - all the kids we teach, seem to prefer turtling them and then 'bombing' each other from the upturned hull. With such a small rig they're also an absolute doddle to right from turtle.

I have to say I can't blame the kids as those boats make better platforms than sailing boats for teaching purposes. Our real teaching is now in Toppers.
