Hi Mary,
Most other sports like motoX are like the formula classes that we are now getting to. I think that formula is the way to go for sure because everyone gets to play, and innovation isn't stiffled like it is in one design. I feel that the "tiger only" and similar events are bad for the sport, except if its a hobie worlds or something, but even then it probably should be an f18 worlds instead. (Is Chevy better than Ford? probably not, so why not let them race head to head under formula rules?) (AND, if one of the f18 designs isn't good enough the manufacturer or owner has free choice to modify to suit)

It is the MANUFACTURERS who have convinced (some of) us that the best event is a OD event.

And, yes there can be HUGE differences between H16s in performance due to setup, old sails etc.
