I think that document refers to the old challenge for the olympic class.
It's "funny" that too many aspects of the board's specs were completelly changed: the RS:X is much more longer, and heavier!
The only good aspect (IMHO) is that the sails are a bit smaller now: 9.5 and 8.5 2 cams are better than 12.5 - 10.7 - 9.0 combination..
Starboard is working with olympic target with the Formula - Apollo project..
I hope they'll be able to succed in getting Formula boards in London!
I'd like to watch the big names compete for Olympic gold!
