A kid can drag their own weight no problem my 8yo at 45kg can drag 45kg. There is always going to be adult assistance when water and kids is involved but at 45kg a mum can help and be involved in the club or sail themselves. Hobie already has production 12 footers that fit within the F12 box rule, that are heavy and presumably their margins are tight to sell them. So I'm going to do what the original plan was thats build a light, modern looking, uncomplicated, easy to rig cat that suits the kids and myself. At 45kg or 50kg Arafura cadets can compete in F12 races and if that gets more kids sailing then its right.
