Ding, don't know what part you disagree with, but I'll assume it's just the number, not a class rules issue.

My understanding is that they came up with a provisional number, and have not received data to correct it.

Is there more to the story?

while I love the idea of a development class, it's just this kind of thing that keeps me from joining: almost instant obsolescence.

But props to you folks who really help come up with the next great leap in sailing technology... Maybe I'll see some of it on my boat in 10-15 years but that's a lot of nautical miles I'll be sailing by then.

Sorry, I momentarily forgot about this gem:

Ben Hall Foiling video. Found by chance.

In regards to the OP; they should knock a couple points off the rating and make foilers suffer in non foiling conditions - guessing. Presumably Texel or other rating systems have already dealt with the down wind foiling speed issue.

erp.... "the down wind foiling speed feature" Um... yeah.. well ah.... here is the thing.... most of the foilers are designed to fly up wind and downwind..... Rating them for a buoys race is not so bad.... The A cat only foils one way right now... The powers that be are refereeing a rule change (s) that might result in foiling both ways...

Right now.... the two way foiling is outside of the rule box and requires a lot of board lifting and lowering... which sucks on a single hander and is impossible to even do if you load the foil up....
So... the game is changing.... YMMV.

Nice scientific formula. Love your rating system.
