They secretly installed a new ETNZ holograph projector in the Gun Emplacements on North Head last night. 

Agreed - nice work @dorox

I Agree. And I'm just astounded when people have such amazingly short memories. Does no one see the similarities with AC35 ? People  were saying exactly the same thing about ETNZ ... and then PB handed Jimmy his panties multiple times in the final 

.... or didnt want to ... 

I can tell you who wont be taking it to the bank .. and thats ETNZ ... they've all been there done that .. once bitten twice bitten.  and you can take that to the bank 

If it's a FB quote you can take that to the bank.  Everything from FB is totally real.

smart money would be on them having a load cell somewhere in the foil arm load chain to tell them exactly how much load is being supported on the foil - which - in a static situation will be proportional to the lift force being produced 

Interesting point - I've been wondering about this too.  Induced drag is a big source of drag . If piercing the surface of the water with the tip of the foil creates a boundary which means that the tip vortex does not form or is smaller then this could be a potential efficiency. 

"Broadcasted" would cost money - unless the Broadcast guys are checking/testing/refining their setup for the actual races ...  But you cant bet good money that every damned camera of note in the greater Auckland region will be pointed at them :D

I agree Pete Burling : "No Look" ... then the wheels over and they're gybing  ... BANG !!! Owned !!! 

Like Pistol Pete did to Slick Jimmy the Aussie motormouth in R8 of AC35 

nothing :)   would that work when the static ports are immersed on a regular basis?    Probably not easily electronically measured and logged. 

Agree.    but it doesn’t need to be sealed. It is more effective if it is, but it’s not an absolute must. 

It will exist - regardless of whether the hulls are lifting or providing downforce. The burning question is if they’re flying low enough to be “in” the ground effect. my bet is yes.  Static ports - yes !! I’d love to see those pressure plots. It’d be a tricky one though for sure. Static air...

Lifting. ok, if it makes it easier WIG shall mean lifting only.    just as an FYI , ground effect still exists for an inverted ( your term ) aerofoil cross section.    I sincerely hope for all of our sakes that we eventually get some exposé from the teams. In reality that’ll be post event...

Why not ? They’re cool 8)

In your opinion....  There may not be any - that’s my point. You only need an aerofoil for ground effect to exist - you don’t need a sealing end plate - either virtual in the case of a vortex or an actual physical structure like a skeg.    Of course if you can put an end plate on a WIG they...

The current crop are a nightmare of aero features ... all of which need to work to perfection together for a car to perform. How often have we seen cars lose a piece of carbon fibre and drop off in performance because of it.  Interestingly one of the most successful F1 ideas in recent years...

Theres more than one scenario in which  ground effect plays a role ..... that where the aerofoil force vector acts upwards - and that where it acts downwards.  On an F1 car, the force vector acts downwards - towards the ground  - with a low pressure area - between the aerofoil / floor and the...

No. Re-reading what I wrote , I definitely did not say ("concede") that it isn't ground effect.  Actually I firmly believe that WIG is what they're attempting. Not a WIG that completely supports the weight of the boat for sure, but a WIG nonetheless - one that assists takeoff and assists...
