Darn it !
There was a write up in Lattitude 48 or some other rag about 6 OR 8 months ago talking just about this. I thought it would be good for my wife too, I dont think it was as formal a school as mentioned above.
I am sorry I cant remember but you might try a back surch of the mags. I can tell you for certian that it was in one of the free mags. you pick up at marinias though maybe Northwet Yachting.
PS; I hope I dont have to wait for years for my wife to get more into it though!
