I started teaching my 14yo son in February and he's doing very well he won't stop nagging me to go out even if there is no wind. He's already learned to tack, jybe, beach and deep water start. He's very persistent and I think he is going to be a great windsurfer. I must be a good teacher. I should also mention that he is high functioning autistic and these kids can take things that interest them to extremes.
