Studying all the hull designs, it looks to me that the Kiwi's & the Brit's both designed the bottom of the hull to ride the ground effect air which will carry more of the total weight allowing the wet wings to run with less angle of attack. The Brit boat looks more forgiving to pilot error but I don't see how it can be as fast due to that double step fat butt.
I did mean spray from the hydrofoils, so if they are bing run with less angle of attack equals more efficient?. my understanding of the British boat is more compressed air (double bubble at rear means more lift ) so quicker up on the plane , but faster ? Time will tell .
@@nzsaltflatsracer8054 that does seem to be the case but why the 'hard chine' design on the INEOS keelson and that 'bustle' I don't for one understand. I can only surmise it's the Mercedes design part of the teams input and where any similarities seem to end. ETNZ seems to have a one step move out of the water whereas INEOS has two steps.
@@DaveandGinny972 My aerodynamic knowledge isn't around sail boats & hydrofoils, it's around race cars, hydroplanes & aircraft so my terminology won't be correct as in hydrofoil - wet wing but I'm sure you guys understand what I'm talking about. Less angle of attack = less drag & when it gets close to the surface it will produce less roostertail. The bustle on the Pomie boat is giving a greater ground effect pressure (lift) in two stages as the hull gets closer to the water but that comes at the cost of more aerodynamic drag even when in full flight. The two approaches are very similar but the Poms appeared to want some insurance against pilot error. It's certainly going to be interesting to see them go head to head.
The challengers will need to put their race foils on for the Challenger Series to give themselves the best chance of progressing, so I am expecting ETNZ to make their move just after that.
@@grahamb8191 Are Britannia using two foils still do you think they will use that patten or use the best out of the two and do you think that ETNZ will use two helmsman on race day
Team Nz. This baby is moving along nicely, this is the flying boat the challengers have to beat for the Americas cup. Some concern in the challengers camps. This boat is tunning up, lifting the grade to formula 1 on water.
Obviously you're not going to find anything about teams openly admitting whether or not they have concerns regarding their boat and the defenders lmaoo That'll be ludicrous. Might as well head home if that's the case... That doesn't mean the original comment wasn't telling truth.
The freeboard on Te Rehutai is very high. It will take a lot of waves for the water spray to go over it. You can compare the freeboards with Luna Rossa at 0:0.11.
Parallax its a pain isn’t it? ;-) Seeing how little of these boats are actually in the water, once they are flying, I’m not expecting to see much differential in speeds. So where one design may get a significant advantage over another boat is how fast they can get up on, and stay on, those foils...& how much the boat slows down if/when the hull touches the water surface. All crews will be at the top of their game in terms of driving the boats, but maybe strategy on the race course might give one an edge over competition. Don’t know, just thinking out loud here. That NZ boat does look rapid though, they all do in the right conditions though.
Early days yet for NZ before people get carried away with comparisons, it’s all too hard with camera angle etc to really tell and how much they are holding back etc ....Magic is a very quick boat and the real threat
I bet the guys in the chase boats are taking a bit of a pounding. Investors never even been on a powerboat that could keep up with these sailboats. It’s a world gone mad...
In viewing the videos of the new boats it seems Luna Rosa is having difficulty in holding a consistent ride height... where the New Zealanders are holding a very consistent height out of the water... also seems the race boats are all now foiling just above the water's surface where the initial boats rode hight our of the water.
They should be better in many ways with their boat since they've been on the water a lot longer than the kiwis have with their boat 2. The fact that the kiwis look pretty good in only a couple of outings is a real confidence booster for them and their supporters.
"And can you really compare their speed?...No" agree but I think the Kiwis are going to be pretty happy with that, 7-10kts I would have picked stronger than that, the wind noise on the microphone also makes it seem faster
Weren't they just making a thing out of exactly this? That's no different than any of the other teams have sailed with each other. All right now back to the video.
So balanced. So beautiful. Going to be extremely hard to beat.
Awesome Footage thank you for your time that you put in for us Kiwis and the world that cant be there 🇳🇿💯👍
Riveting sending blessings from Canada wish we were there sent home March 25 gutted
Jimmy Spithill be like "Oh not again" :)
Thanks for sharing Justin, fantastic footage.
Great footage well done . Anyone think like me , the NZ boats out riggers seem to make a lot less splash/spray than other boats ?.

They are hydrofoils. Most the hull is above water at those speeds

Now we see you , now we don’t . You’ve got this All the way Team NZ
Someones going to need a pilots licence! great pics again Justin, Thanks
Couldnt have amagined this 10 years ago.
Impossible to tell who's faster due to the line of perspective from camera - but I like this footage a lot haha
Only on racing day you will know that.
We were... :)
S S it's actually quite possible.
Thanks a million for posting. Did the Americans go home?
Defenetly more polished, looks smoother and the trimming looks more accurate, improving each time they go out, well done.
Pretty much all were waiting to see... Some speed lined up.. teasing us justin.
I wonder when they will put new fouls on ETNZ.
The challengers will need to put their race foils on for the Challenger Series to give themselves the best chance of progressing, so I am expecting ETNZ to make their move just after that.

Where do you get the team chatter from? I search for that kind of info daily but can't find anything...care to share your sources please?

So this was Pete Burling lined up (near..) against Jimmy Spithill.. I bet there was some feeling..
ha ha ha ha great footage Justin wouldnt it be funny if this was a real comparison rosa be rogered
Justin, I agree - as much as we want to know - we are going to need lots of sampling
It is going to exciting as ever!

There is still plenty of scope for variation in skills and speed; it’s a balance between drag and sail setting.

All four boats look similar in speed and techniques.
If anything, this cup will come down to the team that makes fewer mistakes as the winners.
Awesome! NZ seems to point better, but they are a bit too far apart to tell for sure.
Fitzroy n back in 2 hrs tee hee

kiwis are higher, deceptive
Bad news would have been when the boat in the back passed the boat in front. :-)
Would have been really bad news !

But the Brits seem to tack better than the Kiwis. In light airs anyway.
Do they? As a Brit I hope your right...but I don't see it that way.
The brits seem to have both foils down alot
@@smudge6831 sharp tack manoeuvre I read somewhere
@@DaveandGinny972
I cee watt u did their, cleaver😁😜🤔🍻

The water surface looked different and it appeared that Luna Rossa was in less pressure.
Very fast Team NZ
