Emirates Team New Zealand.
- Thread starter Salty Seacock
- Start date
There was a similar comment in a recent Alinghi video, when asked about tacking from port to starboard.
The sailing behavior change must be fairly pronounced between foil shapes.
Quote from Gladwell -
starboard the anhedral foil is visibly faster, lower down wind and higher upwind. Potentially more twitchy in bad chop/confused sea state.
AC40-3 hit a log and went over. Lots of debris in the water from recent storms. Recovered quickly and carried on...Hit 46kts on the run home....that's quick....
Cup Spy Feb 3 : Kiwis hit UFO and capsize. Exceed 46kts later in session.
Emirates Team NZ strikes a UFO, probably a run-off debris and capsizes in late afternoon training session on the Waitemata. The AC40-OD was soon recovered and completed the two boat session hitting speeds of over 46kts on the reach home.

Yes, quick is right, holy cr*p.
Maybe we get 'bored' by the speeds in all the SGP events but there is nothing else in sailing besides in these class areas going this damn fast. It still blows my mind, they do almost 4 times TWS.

Yeah but thin, high speed foils lack lift at low speeds for take off. As she said in the vid, there's trade offs, and getting that compromise right is the trick.
Sure but think about how ETNZ completely obliterated the Land Speed Record, on the only day they had a chance. Okay, a little different but it was tech demo.
As far as we know Patriot hit the highest speed during an actual AC race, 53.9 or something. They like anyone else would, hit the wall. Salinity, temperature, depth, whatever, that must be about it before you lose acceleration and lift and everything else.
I fully expect that the AC37 winner will be capable of shattering that speed. And if they do solve super-cavitating foils that can go all the way from lift-off to there, like what fighter jets can do, well then.. The Sky is the Limit.

Please have a look at what a super cavitating foil section looks like and explain how they’re going to morph from what they are currently into that. I tell you now no one is morphing a foil from the foil sections currently used Into super cavitation section
I’m not trying to be a dick about it, but it just isn’t happening
look at the sections below and explain how you would morph the foil from the fist one to the last

It’s like one of them is a OD race boat and the other isn't.

But think of all the data the frackers are acquiring.

If only they had data from the front falling off..

You must have missed the video with the accelerometer data.

I must have ..
let me guess it was deliberate 😂

You want Dalton to do this stuff as a gift to the rest of us? Seems like it's part of what it means to compete in the AC. All teams do what they can to gain an advantage and make money. And all teams complain about or protest everything all the other teams are doing.

Maybe part of the foil (the leading edge) is filled with fluid that is allowed/controlled to distort from a wing shape to a cutting edge? Or make parts of the foil supercavitating.

I don’t even know where to start with that
say for a second so you’re right and that’s actually possible. How are they going to get rid of the flap and turn it into a squared off solid section with no articulation
The problem is, you can’t make parts of the foil Super Cav the entire section has to or it doesn’t function
asside from that what you’re proposing essentially is an infinitely variable foil which somewhat falls foul of the rules on foil allocation numbers

Hard to tell but looked like the "banana " had a slight edge. Looks like the bottom batten end extends forward onto the mast past the luff rope suggesting a camber inducer effect, also looks like the jib may have something to stiffen the leech at the clew attachment, all just speculation.
