So I was looking at some footage of the new Oracle AC72 and thinking that the bows looked awfully slender, with bugger all bouyancy. At about 2.00mins in I was reminded why they don't need any bouyancy...
Wow.

Oh Lord above, send down a dove; With wings as sharp as razors; To cut the throats of them mean blokes; That sells bad beer to sailors.

Could be, but in Hamilton's case it's probably more likely to be the Kiwi propensity for doing nutty things in beautiful places.
Found an excellent article about the Vestas Sailrocket in Wired Magazine, including the design philosophy, technological breakthroughs and what it's like to actually "sail" it.
Cracking read.

What an interesting design.
It seems to be a very specialized design intended for setting a speed record, looks like it's mainly meant to sail on starboard tack (edit: I was correct in my assumption, see HERE), either reaching or close hauled. If it were meant for all points of sail it would probably be a trimaran design for stability on either tack. See below:
If you scroll forward to about 6:55 you'll see the trifoiler overhaul an old Hobie 16. When I saw this video it was being screened at a meeting of our local Hobie fleet. Everyone in the room booed when the trifoiler rolled over the H16.
Yup, it rides on foils at speed, and the weird geometry is so that the main body of the vessel points into the apparent wind, rather than in the direction of travel, thus cutting down wind resistance.
well, why didn't I think of that. Makes such obvious sense when you read it. That's why I thought it was drifting to leeward.

blimey. Hope he didn't have any fillings cos he must have lost them on that reach. Far out. What an interesting design. That sail wasn't all that huge and the thing seemed to be sitting on three surfboards... where was the centerboard to stop it drifting leeward— or was it drifting leeward the whole time anyway?

And thanks to everyone else too, for indulging me. It's pretty fun out there and it's nice to share it.
I like big wind, but that day was a bit more hectic than normal. I checked the graph from that location after I got home and the average wind speed while I was there was 38 mph, gusting to near 50. That's pretty much a handful.
