Not much to add, I think Tom covered 95% of it in his post (#3), great job. I'd have to agree with Barry as well:
"That wonderful feeling when you hoist the sails, turn off the engine, feel the boat heel, accelerate and move peacefully through the water."
The only thing I'd add is it's a great passion to share, whether with my wife or a friend. Someone else introduced me to sailing and it was one of the best gifts I've ever received.
