Wouter,

Everything is about performance with you, but that is not a cats only virtue, to my mind a cats best virtue for 7-12 year olds is stability, and putting a small rig on a cat is exactly what I am suggesting. One of the main reasons the Optimist is so liked is its stability. Remember kids don't pick the optimist its the parents and clubs.

Actually its stability and maneuverability and this is a vice with a cat, especially a boardless cat and this could be the killer for the F12 for 7-12 year olds. I am sure that is why Phills concept had boards.
