Here's the only photo I was able to finbd of the "Object" I sailed in the Darwin Regatta.http://manta.org.au/dmr2009/tuesday7july/content/DSC01300_large.html
It's AUS9 in the foreground with the orange numbers. It's a bit hard to see the shape though. I struggled to windward in the mainly light breeze of 6-10 knots. I think I needed a bit more breeze with my weight of 90kg to get it working throught the light chop. Perhaps a little too much volume on the keel for those conditions upwind. It was a rocketship downwind though - especially due to the big head sail I think.

This was my kind of winter sailing - 32 degrees centigrade, pristine blue water, 13 races, free food and drinks every night and a fleet of 16A's and 14 T's. Luckily my motel was staggering distance across the road!
I'm now at the stage of being satisfied that the big head sails are the way to go - there is now a brand new one in my shed waiting for the next regatta. It's the next version from those used by Stevie Brewin and Chris Field in the recent Europeans. The only changes made are a little more seam taper in the bottom panel and some carbon tape drive down the luff.

I can't give anything more on the curved board issue as none were used in Darwin. A few sets came back from Europe so we'll see them on boats when our season starts - also on the new Geltek boats.

Cheers
