Dachopper, South Of Perth has a few of these, (well did last season)
Raced against them in A division and sports class (when they had sports class)
Bloody things go like a rocket. Some of the crew who sail them there actually built them. Hit the SOPYC and see if you can get a handle on who owns them I do know one is an ex-commodore.
But all in all the sure are fast

but handicapped out most times which is a disappointment for them. They always had fastest times but relegated back down the fleet after handicap allocation. Handicap admin wouldn’t leave the system alone, soon as they had a "good" day they suffered big time the following weeks with a horrible score.
