Query: Great Instruction & Complete Intro To Windsurfing

I took one windsurfing lesson and then picked up this book. It was perfect. I have advanced very far simply be getting on the water and constantly reffering back to Mr. Bornhoft's detailed instruction. No other lessons have been necessary so far. The author provides excellent photos and diagrams to illustrate the moves and his descriptions are easy to follow and helpfull. I also found the author's coverage of equipment to be very usefull. If you want a solid intro to windsurfing, you want this book.
