Interesting point about AM using flat bottom for ground effect lift. Seems ETNZ went for hydrodynamic hull, AM aero/ground effect

Hugely different foil solutions

Curious to see what happens in big chop, although that didn't seem to be an issue in the previous cup when flying
It is obvious that AM plans to foil 100%

The NZ foils look like something any one of else would have made based upon the last couple of cups.  The AM foils come out of left field and are a very intentional leap in design.   
Interesting that the bulb carries a slight nose up attitude compared to the fins.

I’ve also got to give the early aero edge to NZ, but that’s only because they skipped that whole mast and sail concept.

I wonder if the AM style foils have better straight line speed, but the ETNZ foils provide more lift, making it easier to get through the tacks and gybes we've seen AM struggle with. It's hard to say if the foils aren't keeping them up in the turns, or if they're still just learning how to tack/gybe these things.

On that subject.. ‘Unmatched Shoes’


He makes some very good points. They are only allowed to make 6 foils!  So that gives them the 2 they launched the boat with, 2 more variations and then the 2 final matching pair.  So no foils to trick the competition.  

Another good reason to have a test boat is to get real world results on your foil designs.  I would assume that NZ will be getting a test boat in the water ASAP.

If the AM foil design is significantly better than the NZ design, then the cup may already be heading back home to the US.  Since the NZ foils look like the GB or AM foils that they started with on their test boats, it may be safe to assume that NZ is behind on the foil development.  And since the rules only allow a couple of iterations, NZ may be in trouble!

If they can race with different foils in Cagliari then they could presumably do so in the Cup too. That would allow a max of 6 different foil designs.

More likely is they’ll design, build and test 5, then eventually build a 6th to match 1 of those 5.

It it at all possible that Emirates Team New Zealand  are building a test boat right now?

One Kiwi article suggested it again just recently but in the past they appear to have been mistaking ‘test boat’ for ‘Boat 1.’ Perhaps ETNZ sources sometimes referred to B1 as a test boat, and the media got confused. So... it’s still hard to tell!
