The B class was what the tornado was built for. It then dominated the class so well that it became almost a one design from the box rule. That's why you don't hear much about it.
Any 20' x8'6" boat can comptete in what they are trying to create with F-20 or o20 , or whatever. Just because the N-20 is the newest boat relegated to the DBS it doesn't mean other boats couldn't also have a fighting chance. Hobie 20s, nacra6.0, etc
Personally I think the baby got thrown out with the bathwater by changing weights and making no min crew weights.
All that needed to be done was to open up the sails and soft goods to any sail loft while keeping the area of the sails the same.No messing with the hulls and foils.

If a man is to be obsessed by something.... I suppose a boat is as good as anything... perhaps a bit better than most.
