A little bit of history:
Back in the "old days" catamarans always sailed straight downwind, just like the monohulls. We were sailing Sharks at the time. Then along came Nick Stan, who started tacking downwind and was beating the pants off the rest of the Sharks.
Bit more History.....
The Wild Thing technique was pioneered by Mitch Booth and John Forbes in the mid to late 80s..... in the 89 Tornado World Champs, Houston Texas, They used it to devistating effect to win the World Championships.... Finishing some races by more than 5 minutes in front of 2nd place......
The boat used was AUS-260 which happened to be the T I later bought and converted. Forbes has the shot gun cartridges from the start gun used, mounted on a plaque in his workshop.
