This dude has invented this move as a low-skill alternative to a paddle roll. In conditions that botch your eskimo roll you don’t want to have to get out of your boat, and then try to get back in.
And if you’re trying for yourself, have a spotter on hand – at least at first. Be Safe!
IMHO, though, it&’s great to have this, but folk need to learn to roll FIRST…the trouble with tech is that it tends to follow Murphy’s law; it doesn’t work when it needs to the most?
