I sort of get it if you have waves like that. We do not in WA near Perth. Just crap shore dumps really or waves that break close to a reef. No long rides. Horses for courses, if you have the conditions then it could be fun. Just not for me.
I may be wrong, of course, but I have seen surfers saying to me "there are no waves good for foiling here", they just were not able to see them. I never went to Perth, but a quick look at google maps show me maybe interesting outer reefs outside point Peron?
Sorry if this has been posted, but this looks like an easy way to get started & learn on a foil. You don't need a boat to pull you - this thing is powered! At just USD$12k it is a bargain!
