as I stated example ages, class rules are that you age out of the opti at 15. yes, some kids size out before that (from your comments, you are an example).
Naa; I'm a microlight; I was about 60 kg until I was about 18! went up to about 65 / 68 while sailing the Hurri and T ; now about 75-80 (lard is good for ski racing!!!!).
