To what level?
Being able to waterstart, turn and stay upwind is akin to being able to order an evening meal in a foreign language.
That may be enough to say box ticked, I've learnt that, but in reality your not going to be throwing down megaloops or back mobes; that's ridiculously hard.
Not trying to knock you personally, fantastic that you've taken it up; Maybe I'm just bitter that after well over 10 years at this I still get shown up by the local kids :)
