Also, I don't understand the usage of Emirates Team New Zealand.
Emirate - Wikipedia
http://en.wikipedia.org/wiki/Emirate
An emirate is a political territory that is ruled by a dynastic Islamic monarch styled emir. It also means principality.
Congratulations to Emirates Team New Zealand for winning the 2017 America's Cup :clapping:.
The performance of these twin-hulled foil catamarans was astonishing, running on average at a speed 3 times the actual wind :o.
How is that possible. Some law of physics violated??Obviously not ;). Here's the Daily Telegraph's explanation:
How is it possible to sail faster than the wind?http://www.telegraph.co.uk/sport/othersports/sailing/10335496/Americas-Cup-how-the-yachts-go-faster-than-the-wind.html
At first glance this appears to defy logic – how can a yacht travel faster than the wind that is propelling it? However, the boats in the America's Cup use rigid wing sails rather than traditional cloth and mast mail sails.
These fixed wings use the same principals of lift force that enables aircraft to fly to drive the boat forward.
The speed produced also lifts the catamarans out of the water. When combined with reduced drag through the water, the catamarans essentially fly above the surface of the water.

Watched it in a tiny taverna on a tiny Greek island - that was a great final race...
Sandro will, I'm sure, be pleased to learn that Luna Rossa have immediately been confirmed as the Challenger of Record for the next event, which will almost certainly be in Auckland in 2021.The Great Sound in Bermuda is bigger than the inner Waitemata Harbour, so I can't see the same sort of racing taking place here - it simply wouldn't be safe.Yes, I've also heard/read that some consideration was being given to the Mediterranean as an alternative race location - either Sardinia, Sicily or the Gulf of Naples.

It will be interesting what happens and I am fairly certain it will be along the coast of a land with more sheep than humans.
the americas cup yacht is now nothing like the old style of boats that used to compete
bit sad really how it has changed since we first won the cup of america in 83

Larry 'Oracle' Ellison lost. Will he return I sort of doubt it.
Both senior Hardy and Connor seem to be happy with the reality that New Zeeland won (again). My guess we will see a more traditional event in four years time that reflect a more national team effort that returns the focus to one on one on the water match racing and national design skills in preparation. As a media event what was supposed to be a spectacle was a big bore. In fact it seems the mega yachts (J-boats) in some respects received more coverage in the press.
Other changes will be hard to estimate but there was a document circulated before the start of this event that team NZ refused sign the intent being to agree to keep the current format. NZ was the only to refuse, so there are certain to be changes.
How is that possible. Some law of physics violated ??
Probably true . . . but still sound like a load of crap to me.
Makes no sense at all. Not what you wrote; but the actual outcome.

I know it seems perplexing but the lift that is created by the wings (sails) is multiplied. It is the same basic rule that allows an airplane to fly (upward and forward).As Av says--it is the same principle.

Absolutely. What lifts an airliner into the air: Air rushing over the wing ... lift, weight, thrust and drag.
How fast does the boat go, running with the wind? How fast does it go, pointing to the weather? If you can answer these two questions, you will understand about the lift created by the sail.
It is one of those abstract concepts that makes no sense. But a sail boat will only go faster than the true wind when it is sailing against or at right angle to to the wind.
The foils (sails) are not efficient with the wind behind them unless spinnakers, genakers or bloppers are deployed, and even still they only seem to be as fast as the wind.
All this about how sail boat goes faster than the wind because it is lifted almost out of water still makes no sense.
Think of this. The wind itself is lifted completely out of the water.
So using the logic others posted . . . the wind should be able to go faster than itself !!!
The NZ defence of the America's Cup is in the early planning stages.
Much as some in NZ want turn the clock back ( as per a few comments in thread here_-- some of the ideas are based on very silly prejudices .
The real fact is that the 2017 formula worked really well in practice -- made the event more affordable - and relevant !
The last time the Kiwis got clever in trying to force the rules -- they got seriously spanked by Denis Conner and USA -- and thoroughly deserved the kicking they got.
Now --some of the same people involved in that losing challenge -- are talking the same sort of bs again.
If they were a 1/4smart -- the Kiwis would realise their best success has come with refining the product -- and not thinking they can move the goalposts further than everyone else.! ;D
America's Cup 2017: Auckland faces shakeup for hometown defence
But it will all depend on which class of boat Team New Zealand chooses to go with, and CEO Grant Dalton's already dropped a few hints - catamarans could be out in favour of the more traditional mono-hulls.
"It's important we don't take away from the yachting aspect of it. It's still a race of yachtsmen, and I think just pumping oil around the boat isn't necessarily yachting," he says.
But other teams have already indicated they want the flying machines to stay.
"It would be a mistake to move away from the style of racing that we now have - I think it's been a real revolution in the America's Cup and the sport of sailing in the last five or six years," says BAR skipper Sir Ben Ainslie.
"I just can't see them wanting to change from where we are right now back into the old keel boats, I think that would be a big step backwards," adds Artemis skipper Nathan Outteridge.

Fun stuff
Jay, that report is several weeks old. It also has glaring geographical and typing errors, so I really wouldn't take it completely at face value in any case. As for the type of yacht to be raced, it's interesting that Peter Burling, the winning skipper, has been racing in the Moth World Championships over the last couple of weeks - single-handed small yachts which also foil. He has already expressed his opinion that he wants to see the flying catamarans continue in some form.
I can't see any comments in this thread which suggest a poster prefers a return to the "old" type of boats. As for the rules, Team New Zealand won. It's now up to them to decide how the next event is run - not you or me.
Anotherkiwi
I believe our resident site copy and paster of inaccurate / old info is referring to Bdhva's earlier post...
May be it's an age thing, but I also prefer match racing to to a drag race - which the foiling M/hulls have become
As for Denis Conner and 'Plastic Fantastic' - the NZ 1987 entry - that was made of composite materials comment: " Why would you want to make a Plastic Boat - unless you wanted to cheat?" ..He was lucky that the wind finally got up in Fremantle - where the Aussies defended the cup - as he nearly went out in the qualie rounds - where Stars and Stripes was performing like a dog in the light stuff...
The foils (sails) are not efficent with the wind behind them unless spinnakers, genakers or bloppers are deployed, and even still they only seem to be as fast as the wind.
Whaaaat ?
Even 4 years ago these foiling cats were going 2.79 times faster than the wind - downwind

Well--it happened. The dead head Kiwis want to turn the clock back to another era.
Absolutely clueless moronic small minded series of decisions.
I can only hope Larry Ellison wins it for the USA again and restores it to a real accessible event!

America’s Cup Will Return to Monohulls in 2021
The Cup in 2021 will return to monohulls, the boats with deep keels that were part of every America’s Cup from 1851 to 2007
http://www.nytimes.com/2017/09/29/sports/sailing/americas-cup-2021-monohulls.html
The quoted part is only partly accurate - as one defence was a USA Multihull defending a giant NZ monohulli
Sailing multi hulls in Kiwi's waters would be fatal to sailor's nasty short chop.
They 'owners' of the cup have a clear guiding principle and that is to return the Auld Mug and winning (or defending) it to the principles that founded it. So a vessel built and designed by the country that enters it. It should be sailed by nationals of the flag that it sails 'under'.
How many 'Americans' were on team 'Oracle'?
I suspect the Kiwi's can turn it around.
The windward foil extending so far out will mean the hulls of the racing yachts are unlikely to get as close in the vids - as surely the windward boat making contact - might damage the leeward boats foil ( innocent party in most scenarios)
I suspect we will see Moth type foils in the near future.
The concept of foils that (re)move them selves from contact with the water seems bizarre.
