RE: When to start
I started when I was 7 years old on a Starboard Start with a 1.5 sail. After a month or so I moved to the Starsurfer. I help in the summer with the local windsurfing camp and there are a few 4 and 5 year olds doing it and they seem to get along just fine. The main thing is to let them go at there on pace and keep it fun. Here is my web site if you want to check it out.
