American Airlines Pilots made one too, I'll see if I can find it.

Here it is: http://www.youtube.com/watch?v=lu42f-pHClw

She passed the test.

So at best vmg of 42 knots, that makes the Tractor still probably not as fast as the current crop of Tri's which I think are averaging around 38 knots for 24 hours at a time ?

That jib looks like a hanky when they pan back. Kinda makes you wonder if there is a point they'd just drop it?

Designing a boat for 80% reaching and designing a boat for refined windward leeward are two very different things.

hopefully she'll be flying again in feb.

O.K., this video has my curiosity up. The boat is a one design SL33, designed by Morrelli & Melvin and built by Hakes Marine . The video shows it foiling nicely, but it looks like it has a curved foil on port (windward hull) and "possibly" a L foil on starboard. Can't tell what the rudders are. Here are some pics of the SL33 foiling with a soft rig. Looks like it might be an S foil on the windward hull. Any body have any knowledge here?

Obfuscation. Public released video. I wouldn't rely to heavily on what you see.

This isn't really knowledge but, apparently the 33's are test platforms and they are trying every type of foil they can think of on them. even the 72's have 2 different foils often.
from the photos it looks like the curved part of the foil is mostly in the hull when in the down position. the business end is an "L". the cant of the "L" is something to play with as are the tip foils shape/angle, etc.
Rudders have similar aspects to play with as well. it seems to me that an end plate on a daggerboard would help quite a bit to windward as well as become a hydro-foil off the wind. finding a happy medium between these 2 points of sail and the characteristics of the end plate would be a job, and require all sorts of testing.

there is some debate as to whether the extreme fineness ratio of the 72's may be fast enough to eliminate the need to fully foil in an upwind/downwind course with some 1-2 minute legs.

I really don't think we will see them foiling upwind. I think they'll use the foils to make the boat a little lighter in the water - but not foil born. Downwind, however, probably.

Agreed, the no foiling to windward seems to be the consensus.
Most likely they are canting the lee board for sailing off the wind, which when combined with the wing tip or "L" gives the enough vertical lift to fully foil. Their speed may or may not increase, and their angle downwind may improve. Some speculation says both speed and angle will improve from foiling.
They are limited in the number of 72 dagger boards that they are allowed to make, but they can make as many SL33 or ac 45 dagger boards as they want to help figure this new development out. Mr. Melvin is on the design team for NZ so it makes sense for them to use the 33 as a test platform. Atrtemis focused on the big wing first and don't appear to be in agreement that fully foiling is the way to go.
the original mockup of the 72s showed banana boards, but i imagine that they work better on small cats that are crew weight trimmed, and big tris that have a regular board in the center hull. once they tried "L" and "T" foils they didn't look back.
can you imagine flying into the leeward gate at 40 knts., having to round up and crank the daggerboard to a de-canted position? what a learning curve this contest must have.
On the jibes it seems like they would set the new board before the jibe, but when 17 capsized going into their jibe they still had the 1 board up. if it had been down maybe both hulls would have been clear of the water and nosing in would not have been an issue.

Dear Santa:
All I want for Christmas is a wing!
