America's Cup Winner Returns... here's what she's hiding

Last week Te Rehutai returned to the water. Heralded as being a 'generation ahead' of all challengers in Auckland. It seems ‪@EmiratesTeamNZ‬ are still very much keen to hide the secrets to her speed.
What has changed on the successful Defender? How has she been adapted for her second life as a test platform? What does the progression from Te Rehutai to the LEQ12 tell us about ETNZ design pathway?

Kiwis are born sailors just like us Australians. Can't wait for the cup to start. It's going to be another NZ domination. Sailing has come a long way since I raced 125,s in the 1980,s.

[@Chris.Davies]

Bring on the gas-feed super-cavitating Turbo Button! If enough excess power can be harvested by the cyclors, then an additional high-pressure reservoir of air can be built up over time. That gas can then be vented through tiny holes at the leading edge, placed so that the foil is completely surrounded by a super-cavitation bubble of air, which would temporarily drop drag by an order of magnitude, effectively giving the boat a Turbo boost effect when used.

[@roslynhita6149]

soundz a good idea

[@isaack2274]

I could understand this for lifting the foils during turns when they lift the foils but air over the foils would mean they would lose lift.

[@Gottenhimfella]

@@isaack2274 Possibly when they exceed a threshold speed it's better to supercavitate and lose lift by a constant and predictable amount (which they could compensate with flap angle), than cavitate unpredictably, intermittently losing most of their lift every time it happened. Over about 50 knots, cavitation is unavoidable. I'm not sure whether Chris's specific proposal would be practicable but I'm sure the teams are considering all options.

[@jaysparc]

Or you could give them Indian takeaway before.

[@harken9978]

[@gafrers]

Quality as always

[@youroddsox]

Interesting vid as always. Love the elegance of the simple etnz foil design and looks like Ineos are trying to decouple the various forces generated by the foil, assuming based on the predicted sea state and better maneuverability. If possible could you do a vid on the rudders and to see if these are evolving? As a guess I'd say etnz are are thinking foil lift/drag is king and using the rudder/other methods to control ride height, heal etc. Looks like ineos think best boat control / maneuverability is key. Interesting to see who is right but ac history does suggest the fastest boat in a straight line wins but maybe its a boat for Ben to win starts and errrrr be Ben Ainslie....

[@timransby1774]

ETNZ, I think, have grasped - maybe more than any other team with the possible exception of LR - that the foils are the most important thing when it comes to performance. It's reflected in the cleanliness and simplicity of their designs - and the outstanding implementation of those designs into a physical structure

[@paulsmith4220]

Actuators are the movement engine, but what happens after that is open. Levers, cables, lines, sheaves, balloons, slave cylinders, ramps, flexible forms etc. Off course the ultimate I'd to build a self regulating foil that flexs appropriately in response to changes in realtime. This opens the possiblity that the energy comes from one part of the foil and hydraulically transferred to another. Only small movements are required to effect big changes in trim. So it could be simple of complex, but so far is a very elegant solution that seems to work well.

[@jhideout]

Great stuff! Love all your coverage of these new cup boats. Are the crew pods allowed to be completely covered?? Can't wait for the next ...

[@MozzySails]

not completely. there are set sizes for the openings for each crew position (with slightly larger openings for cyclors). What you see on this boat seems to be what the rule says (except they have 10 crew pods, rather than minimum of 8).

[@trevorgissing1208]

Another great story Mozzy; your analysis of what the teams are doing design wise is fascinating and fills in a lot of gaps with info (propaganda) we get from the teams. I was out on Auckland harbour last week and saw Te Rehutai in action; she certainly looks quicker than she was in the last cup, but didn’t see quite as “nimble” in the tacks/gybes. I believe that at some stage they will take her out into the outer harbour to get into the swells; that will be a good test to watch. I’m a bit nervous as to how she’ll cope with the conditions in the Med.

[@BRMCaptChaos]

Great update Tom. I don't understand why raising the jib tack up is optimal on this size of boat. Surely you would want uninterrupted flow along the foot on a sleek deck, not allowing the pressure to equalise I.e. using the deck as a seal. It's a big chunk of sail with low moment to lose. Also, on "hydraulic" actuation (I may well be way off) NZ may be remoting the motor to the arm, so to power the hydraulic system independently. It avoids some plumbing issues.

[@Gottenhimfella]

Tom did cover this. He pointed out that raising the sail (to tighten the leach) is often only a short term measure. It's also possible the kiwis may add extra roach to the foot of the sail which folds over when the sail is hauled fully down. The aero and weight implications of a 3D car path (as being trialed by Ineos) are not insignificant.

[@peterrose8944]

Mozzy you are the greatest

[@dundeedolphin]

Is there another KZbin channel with less resources that offers greater value? I haven't seen one. 👏👏👏

[@timransby1774]

interesting !! Now that you've "outed this, it makes me think that the flap actuators could be horizontal arms with articulated attachment joints on to electrically powered screwjacks.

[@charlestoast4051]

There's certainly some sort of bolted on access cover in the area you believe the actuator is located.

[@Gottenhimfella]

The first word of Te Rehutai does emphatically NOT rhyme with tea, for two reasons One: in Maori (as in Spanish and Japanese) the "e" sound is the e in "egg". This is true for all words, and so it applies to the "e" in Rehutai as well Two: unless there is a horizontal bar (macron) above it, a vowel in Maori is clipped short, not held long like the vowel in "tea". Sometimes the way you said it sounded spot on, and good on you for taking an interest in getting it right!

Have a look at electro hydrostatic actuators, an electric motor directly driving a hydraulic motor. Allows electric power transmission but hydraulic actuation. The foil actuator could be one of those? Can require some quite hefty currents. Usually the electric motor reverses direction to reverse the hydraulic flow, but that can happen quickly. How often are the foil flaps adjusted?

[@jacksongreen1107]

Pronounciation for English accents: Tear Reh-hu-tie, with Rehutai run together quickly. For bonus points, you can roll the R sound like in a Glaswegian accent.

[@tomosorio7530]

Comparing this to Ineos W, with its lumpy actuators hard not to wonder/worry: is the Ineos W foil actually a clever way of testing multiple foil 'strategies' in one? (As with their failed towing mast tactic, developed a clever approach to beating the rules for development restrictions.)

Bear in mind that if Robs theory about ETNZ's 'banana' foil is correct they might not have to house an actuator at all, or at least one that is to small to actually move the flap and doesn't impact the size. Great video as always Mozzy, keep up the good work 👍

Amazing intuition and investigation as always Mozzy! Question: You say it is all hydraulics this AC. Are any electrical systems allowed? If the Kiwis have cyclors controlling flying height like they did in 2017, will they need to manipulate hydraulic rather than electrical control buttons?

[@MozzySails]

Electric is allowed, but only to move valves and clutches

[@pierocostantini2864]

I think ETNZ, having the upper hand, made the best choice for development. Using the old AC75 which is still already the boat to beat, and then the double AC40 for a/b testing, put everyone else in the corner. LR, knowing that its AC40 would come too late, had no choice but to develop the LQ12. But they did it in the best way: by making a scaled-down version of Te Rehutai, as LR AC36 was not adaptable to the new design vision. The new ETNZ AC75 will probably be an evolution of the earlier design. And in that sense, having already installed on-board cyclors, they are a piece ahead of everyone else.

As the rules were born from negotiations, ENZ subtly inserted language that allowed their electrical actuators without anyone catching on to their plans. Note that ENZ has already found a way to allow two boat testing. One must also wonder what other clever manifestations were hidden in the rules.

I'm a kiwi and I have no association with our America's cup team but I've wind surfed, kite surfed and now I've wingsurfed for the last couple of years. I don't see what's complicated about this, in my own foil construction of my own designs, there's a point in high performance at which making a wing thinner only results in unacceptable flex. (I am talking about carbon fibre here and I'M HEAVY so I flex things.) So you don't build ultra thin because it's counter productive. And the core of any wing is dead space, compression, tension and twisting loads are at their extremes by the skin and at a minimum in the inner core. So the answer is that if you are clever with what you fit in the core, you are only limited by your imagination and material properties.

[@Trajectionable]

Finally a voice of sanity. No, it's not at all the same race, meaning it's not really the AC. It's a blind pursuit of technical speed, egged on by a vague nationalistic hubris that holds it there, with no observable, residual regard for the essence of the Race. Sad, because there are half a dozen superior sail classes who still race real boats on real courses engaging real dynamics and seamanship, and not this banging off the out-of-bounds in bicycled, flatwater, inland Moths run by a peculiarly narrow interpretation of both tech and class. It's killing the Cup. Judged by the want of replies to your observation - and anticipating the thumbs-down due mine, apparently this is fine.

[@trep53]

[@fabmanly1070]

Crazy/stupid question; could ETNZ be using skinned’ foils? Foils that have some sort of skin or whatever, pseudo malleable coating over the entire foil covering the hinge mechanism/flap? There is only one slit in the centre separating the two flaps either side and every other surface seems to be covered.

[@jasonrzoska1688]

My guess is ETNZ will use the rudder for trim and have no moving parts on the foils.

[@Gottenhimfella]

The tabs on the main foils are for controlling lift (gross changes to overall angle of attack via camber) rather than trim of the entire boat (which does affect angle of attack of the main foils, but only at the fine tuning level). Otherwise the main foils would always need enough camber (ie lots) for low speed takeoffs in light airs, and the drag penalty at high speeds would be massive.

On the actuators - if it's above the waterline does it matter whether it's hydraulic or electrical? Your animation shows linkages to a lever in/behind the bulb which then controls the flaps. And another question - does the amount of flap actuation (degrees up and down) important to the issue? Fewer degrees, easier to manage the linkages. If Team NZ can live with lower ranges then they can keep everything smaller?

[@MozzySails]

I think either can be waterproofed. Whether it is electronic or hydraulic only really matters in terms of what is allowed in the rules. This cup they are not allowed electric, it has to be hydraulic. My theory is last cup they used electric as a means to install less actuators, and therefore reduce mechanics within the foil.

Formula 1 is losing its appeal as the true driving skills and racing between cars is being nullified by technology. Racing fans often prefer to see results based on drivers skill. Remember "the good old days" when the Americas Cup was about true match racing, good crew work basic navigation. But these boats are good to watch as far as speed goes, no doubt about it.

The crew know how to fly boats. Everyone knows how to build one. NZ know how to fly one.
