I just got an old book called "The complete guide to shortboard sailing" by Jeremy Evans, and there's this photo of a race at the Gorge:
Robbie is clearly seen as US-1111, but who is this guy KA-1?
US-9 is Nevin Sayre. Can anyone remember D-1. Thorkil Christensen?
Whoever it is must be pretty quick coz they're in front of Robby!
If you believe this list, it's Susan Day from NSW!

I think D-1 is Tim Aageson (spelling) or Thomas Persson.
The guy behind Tom with same colour rig is Alex Ageura I think.
And Dave, it was spelt Susan DEY and your right. The chicky babe from Partridge Family
Shear tip said,
Apparently he is a Japanese autogyro
"The Kayaba Ka-1 was a Japanese autogyro, seing service during World War II."
which would explain why he's flying.
I'm pretty sure it's Tom Luedecke, he was fast enough to be close to those guys and he used to ride for tyronsea which is the insignia on the sail, so yeah thats Tom Luedecke for sure.
Anyone know what happened to Tom Luedecke?
Gee, some of you guys must be really OLD!! 
The book is from 1985, so the pic must be from that year or earlier, if my understanding of the nature of linear time is correct....
Another obscure fact. Tom also was instrumental in starting AHD way back!!
That photo was when the big teams and their huge budgets were around.
Mistral/Gaastra and Tiga/Neil Pryde were just some of them.
