We have a local world fireball champion, when everyone in fireballs were using snuffers he opted to go back to the bag.
Using a 1:6 system the skipper would hoist the kite while the crew threw the kite into the air. the results were sets inside 2 seconds, the fastest in the fleet. a side bonus was the boat didn't fill with water from waves going down the snuffer.
apparently it was a easy worlds to win as no one ever got close.
