...... and in my view caters for the 2 up light weight market.
Lightweight for the F16's, or catsailing as a whole? From putting 365#'s on my own Viper, it handles it quite well.
Heavyweight big boys has gotta be the F20, midweight to big boys F18, lightweight duo ( man and women or dad and rugrat ) F16, solo dad ( when he doesn't have a crew ) F16 and don't forget the A class for the techies, that would be my interpretation of things.
