We moved to a house on the shore of Cayuga lake when my son was 5. He has been sailing ever since and has an intuitive grasp of how to do it that seems sort of like speaking a language. He doesnt need to think about it, he just KNOWS when the sails dont look right or when the puff of wind is about to get to the boat. This is all about actual sailing, not the other systems on a big boat like the engine, electricity, etc. It came from sailing the laser and the hobie cat with his buddies and seeing how fast they could get it to go before they ended up in the drink. I think I will never have quite as instinctive a grasp as he does because I came to it later in life. My daughter is two years older and doesnt have the slightest interest in it even though she had all of the same opportunities. Go figure. Every kid is different and if they have the bug you cant stop them and if they dont then they just dont want to.
