No, and it will takes years to fix what he has destroyed.  He doesn’t get any more blame than he justly deserves.  Just look at his childish and self serving response to the election.  Any child would be punished for his actions, not encouraged.  Look at how he is trying to sabotage our country as he exists.

Agreed. He has laid waste to everything in his path. He's the most disgusting, repulsive and embarrassing figure to ever be president. What his victory in 2016 said about the ignorance and stupidity of our population is also a global embarrassment. Half of our population is completely detached from reality.

The scary thing is that so many Republicans holding office remain beholden to (are scared of pissing off) Trump’s base. The vast majority are biting their tongues even as he tries to overturn the election! Crazy times just got even crazier..

nothing to do with the ac..but my many american mates say the root of the problem was to combine two countries into one. should have had one racist, hillbilly, mega-capilist, i could go on...and another country of progressive folk that were closer in world view to the rest of the developed world. after all, just look at the popular voting split.

The contrast is interesting.  Torturing a hull line is usually a way to make a rating rule “think” the boat is slower.  In this case it is essentially a box rule so tortured hull lines are based on what the simulators spits out.  Brit Chance went down that road once too.

They are more than 100m apart which was the other criteria suggested (though neither were accepted as definitive). If you deem that any boats sailing in the same point of sail for more than 30s are coordinated then madness lies. For one thing there are only 4 points of sail of interest with these boats, and there are 4 boats. So ironically the only way to avoid that situation would be to coordinate your turns in some way

Really? lets look at that

1) How many boats are there in the regatta - 4. GB, US, LR, NZ

2) How many points of sail are of interest - upwind stbd; upwind port , downwind stbd, downwind port. There is no reaching

3) Are they more than 100m apart when they are on the same point of sail? Yes. That is about  boat lengths

So if 100m is not a factor then given that waters are restricted the suggestion is that if 2 boats are heading on the same point of sail for more than 30s then it would be "coordinated". That suggestion is the utter nonsense because it would mean that if all  4 boats are out and on different points of sail and one turns, one of the others would have to turn within 30s. Thus taking non-premeditated cues from each other which NZ argued was coordination

I know I'll probably get bagged for being an ETNZ fanboy but.....  Isn't there are considerable difference in driving style between Burling and Barker.  Barker as is his style is standing upright, body on a lean and head to one side looking predominantly forward.  Burling down in the boat (sitting?) - presumably still doing what he was doing in Bermuda - a set scan circuit looking outside the boat then instruments - left to right (made that up) - adjust - repeat.  No doubt the instrument scan is in a particular order.  Reminds me of my pilot training - scan outside - left to right - scan instruments - left to right - rinse repeat.

And they will all want the water where the race courses are for that wind. That's not coordination. But in any case you have chosen to ignore the 100m that was suggested WITH the 30s interval. If not 100m then how much separation do they need? 1000m? 10km?

They are not within 100m so not in the same patch of water

No shit Sherlock.  You can not forget that as high tech as people want to think about these boat, they are still sailing!  Being able to match up wind shifts and make the most of what the conditions give you can more than make up the drag of one guy standing in the wind.

LOL.  As we know every little advantage adds up. Now your version is an old way of doing things.  Again getting back to planes after a number of serious accidents caused by human error cockpit management was completely overturned and CRM (Cockpit Resource Management) was introduced i.e. cockpit crew all had a responsibility for scanning and were taught to say what they saw.  In terms of sailing you will find that Tuke, Ashby and Burling are all looking for the shifts PLUS regardless of what people will think there is a clear defined wind shift cycle that develops that you can align with the instrument displayed data - those three will be working in sync.  If their work environment is optimised for that outcome then that is a plus. 

In my opinion it looks to me that Barker is in a dated mode where the helmsman called ALL the shots and had a damn sight less data to scan.  Remember the quip from the last Cup?  "Burling looks like he is Driving Miss Daisy".  Remember Jimmy damn near up on the side of the boat scrunched to one side?

I would not be so sure.  The keelson for a displacement boat typically would extend to the stern of the boat.  

In a flying AC75, the keelson is added to help aero flow and to give some end plating with the water.   It has been stated that the typical AWA for these AC75 is about 15 degrees (both up and down wind) when they are up on their foils.  

If you look at 15 degree AWA, you can see that any wind that hits the side of the boat after the mast (where the mainsail is) will never reach the other side of the boat.  So any wind pressure on the sail can only be end plated by the wind that hits the boat before the mast.  So extending the keelson much past the mast should have very little impact on end platting the mainsail.  AM is the only boat to take this into consideration and have designed the stern of the boat for other aero effects.

I'm pretty sure the ETNZ keel also tapers away at the stern, from a maximum depth around where the mast is, down to nothing as it reaches the transom.

Also I note you drew AM boat one there in your diagram.

He sailed brilliantly in the "abandoned-due-to-high-winds" day in SF/AC34. He owned that first race while it lasted and just one of the things that lost ETNZ the cup.

Remember the crazy day of the pitch-pole in Bermuda? Most of the teams where coming apart at the seams ... Artemis ripping off and discarding bits of loose fairing, Ben saying it was the single most extreme day of sailing in his life. Barker smashed it round the course and came off looking exhilarated!

If the wind gets into the upper limits this time, keep an eye on Deano.

It is about guesses over where to make compromises between hydro and aero. LR and AM look the sweetest aero-wise but they are gambling s bit.. 

I see a lot that I like about the NZ hull, which makes me mildly embarrassed about my initial reaction the GB B1. Not that it's all necessarily limited to ETNZ, but overall:

• Bustle: Liked this from B1, saw a pc screen on the recent "design/construction" video where a designer was looking at the bustle's wetted area. Virtually enough volume to support the boat, whilst maintaining a narrow drag reducing canoe shape.
• Forward Flare: Should help provide a quick recovery if they have a nasty bow-down plunge.
• Flat Aft: Like performance power boats, helps keep the boat flat when accelerating in displacement mode to get over the bow wave, which the forward flare also helps with it's minimal lower volume.
• Maximum Mid Waterlines: Hard angles there to max out the waterline width for better RM.
• Crew Pods: As narrow as they could get away with, tucking away the crew, and nicely streamlined aft for good aero.
• Clean Aero Deck: With the narrow crew pods, very little to create turbulence and extra drag, nice trailing edges for vortex reduction. Well rounded forward gunwales to encourage laminar airflow toward the sail/deck interface.

Not quite so convinced about the frequent under-hull "end plating" comments. Except in flat water the boats maintain more distance from the water surface anyway, to avoid "wavelets", and I see hard edges on some others that could increase turbulence. Plus at the air/water interface the air is barely moving. I'll accept it when I've seen CFD airflows demonstrating a positive effect.

Despite the offer of my left testicle, ETNZ rejected my request to observe their CFD designers at work etc, so this remains speculation.

Britt Ward noted on TE’s show this week that the GBR skeelson  does not extend back as far as on some other hulls, there’s a significant gap between it and the rudder. He suggested it may be for weight-saving. 

My understanding is that it's done to avoid turbulence from the skeg/keel affecting the rudder.

which one doesn't look like the others?  Patriot is the only one with the keelson tapering off so dramatically just behind the mast.  It was a very conscious design decision and was made in the overall aero flow of the hull.

Love the minimalist look of the US boat, but surprised European Airbus are the partners rather than Boeing.

Also hate the look of the short stubby jibs, the way the gap between leech and mast opens up, but I guess it’s unavoidable?

Boeing doesn't have the best reputation for flight control right now - could have been a catastrophic partnership.
