 I think a few people need to stop getting over excited about the similarities. 
Ineos B1 stern wasn’t flat.

infact theyre completely different.

The height of the topsides at the top of the curve, maybe, but Ineos topsides were straight and did not taper down to the stern, the deck layout is open compared to completely enclosed on ETNZ, no bustle as opposed to a very obvious bustle and a completely different bow profile. Chalk and cheese!
Fracker No2 not that flat arsed either.

Crikey some of the TNZ naysayers need a trip to Specsavers.

I find it quite amazing some of the similarities that ETNZ B2 has with the other boats. But given ETNZ wrote the AC75 design rule and as many have pointed out here they had a massive head start on everyone else. How anyone thinks ETNZ have copied one/some of the other boats, they well and truly have their hand on their dicks.

Would the deck design increase a funneling effect across the foot of the main?  Generating more power than the other boats? As the wind passes through the slot, instead of just spilling at the back, it’s diverted down along the foot of the main?

Is it true that 60/40 power split across the main? So it would make sense to divert even more of that wasted power along the foot?

As most of the power comes from wind going across the outer side of the sail that would make sense. The wind would be compressed as it passes between the outer/leeward side and the inner side of the hull/channel?

I’m  no designer or great sailor.....

These shots shows just how much of the deck/floor/sole has been cut away compared to the Frackers with the mast sitting on the ball atop of the pedestal.

The only thing these two have in common is that they both float.

Just like UK B1, but they obviously didn’t think it was worth it or they would have put it on their second boat.

Are you sure?  The crew walls on NZ2 are high enough to totally enclose the crew, where as the crew on UK B1 could easily rest an arm on the wall.  Also, don’t the rules state the exact height of the mast base in relationship to the foils.  If you take that into consideration, the decks look very similar, with just higher walls on NZ

I don't think this comparison quite works: NZ2 the crew are standing on the hull, GB1 they were in the cockpit. Walls could be similar height, but possibly shorter on NZ2 given the extreme geometry.
