Why do you think ANY F18's... much less 8 will be on the start line?

If you don't hear a buzz shortly... I think you will have a hard time getting a fleet.

Hell, the steeple chase did not draw any F18's either... Seems like the owners are not that keen on distance racing.
Besides, If you are doing 500 miles... you want the fastest ride you can get.... That HAS to be a 20 of some kind.

The newest Nacra 6.0's has to be at least 8 years old by now so that leaves the Nacra 20. What else is out there?
