This isn't quite on topic as my friends aren't learners but it does point out how hard it is to get into the sport.
I have 2 friends..One wants to get back into it after sailing a Hi Fly 300 in all winds back in the 90's another wants to go from his 1970s wally to a shortboard.
We've been to a few windsurfnsnow demo days and they are great.They have them enthused.
The problem is there is nowhere they can try different boards locally and demo days often dont' coincide with enough wind to try shortboards.They could try & go to Sydney but they'd be lucky to get a windy day & access to equipment.
The guy who wants to go to a shortboard has had a few goes on my Tabou 125 & 95 & loves it but wants to try other brands.
Now Boardcrazy has gone to the other side there is nowhere locally he can try boards.So unless he just bites the bullet and decided he' ll go with what he's tried ( Rockets) he has to just get advice and hope he'll like the choice.
Same with my other friend.
We don't have enough people sailing locally to let them try other boards + who would let an unknown inexperienced sailor use their board & risk it getting damaged ( other than me but I know them .

).
It's all a bit in the too hard basket.I suppose its always been abit like that but in the 80's there were heaps of people and the boards weren't as fragile so maybe more would have given them a go.
I imagine its even harder further away from sailing areas.
