American Magic Team AC75 Yacht Defiant Auckland New Zealand September 25, 2020.

[@MaoriViking]

How privileged are we to have this fantastic footage to analysis and enjoy. Many thanks to AirflowNZ Travel for the amazing work and passion you show. A highlight of my day :-)

[@airflownztravel]

MV, Many thanks! Mike

[@robertfairburn9979]

From my amateur eye AM are starting to look more polished. They seem to be controlling their height well

[@maxhugen]

Does look that way today. Might depend partially on the steadiness of the wind? Looks like they were flying a bit higher at times, possibly to reduce foil arm and rudder drag.

[@catyamman]

Thank you for all the video. Looking forward to seeing these hulls or "lack of them" compete.

[@airflownztravel]

Jerry, my pleasure! Mike

[@BhutJolokias]

As an affirmed landlubber, I can't get over how fast those things move.

[@airflownztravel]

BJ, and getting faster each week! Mike

[@Woodbug-b7t]

These mono's turn on a dime and keep foiling at speeds where previously the cat's would have bottomed out and stalled. Impressive!

[@airflownztravel]

Swampy, they sure are! Mike

[@skyak4493]

They may need that maneuverability. I would sure love to see what happens when two of these try to bugger one another's air. I bet each team has developed incredible video simulation games.

[@shaneweaver1720]

how fast are these boats going and what is max wind speed they can sail in

[@izziebon]

I understand its around 48 knots?

[@maxhugen]

Wind speed limits for the AC are 6-24 knots. All teams are a bit coy about top speed, but say "high 40s". They run into probs then with cavitation.

[@jpm74]

You can get pretty accurate get time distance speed estimates from all the videos when they sail perpendicular out of frame to a still shot with the fastest speeds about 48 knots. Here, Defiant was doing about 36 knots at 4:18 and 38 knots at 6:11. And she was clipping that during what looks like a light breeze day!

[@sjdlkadjklafkjldkjfd]

This is look a whole lot better from the previous videos. They seem to have the stability of the boat worked out a LOT better now. I am not seeing them touch down all the time. Previously they looked somewhat wobbly. Their tacks and gybes, however, have always been spot on and so far look the smoothest with very few touchdowns as they come around. Emirates seems to still be having trouble with that the last footage I saw. I wish I could say this will be an interesting race (cause it won't be. It will be an interesting start and then a boring drag race like all foiling match races) but it does look like the boats are going to be cool to watch at least.

[@airflownztravel]

Matt, very interesting comment, thanks, Mike

[@skyak4493]

ETNZ touchdowns in previous vids looked like ventilation. No change in angle, just a drop. In the previous video they have different T foils port and starboard -a manta and a forward bulb. Both had wide span and some large fences. The intersection is the most challenging point and the 90 deg is more difficult to keep constant pressure than the 120 AM is on. T should be more stable and easier to sail but it hits cavitation problems before the Y. I don't think there is a way around it. IMHO ENTZ team was ahead on control but their foil development looks like it is running late. If they just are hiding their real foils I don't think anyone is fooled.

[@aquilarossa5191]

This makes me think if my grandad. He was almost unbeatable racing on the harbour. I remember walls just chocked full of trophies. No Americas Cup in those days. I only did a bit of sailing. I like it, but was always too busy away working down in the Southern Ocean for months on end.

[@airflownztravel]

Aquila, let’s hope you can get some time off and enjoy the racing, Mike

[@mastrake]

Nice! I can't wait to see these boats on the racecourse.

[@airflownztravel]

Rick, imagine four yachts out at the same time! Mike

[@mastrake]

@@airflownztravel I can't wait!

[@jamso1086]

Thanks for the uploads, wish I was there with ya.

[@airflownztravel]

Jim, many thanks for your comment, Mike

[@skyak4493]

So, does anyone think this configuration will see life beyond the AC? In my head I am trying to imagine a box rule entry. What does this look like in a 6.5m?

[@airflownztravel]

Skyak, time will tell, Mike

[@team3383]

Thanks again for phenomenal content and good filming. Is it me or does Defiant seemingly have a much bigger "rooster tail" off its leeward foil than the Emirates boat ?

[@airflownztravel]

T33, all yachts have the same foil arms so it must be height out of water. Thanks for your comment, Mike

[@stubrown3575]

What days and times do they usually go out ? I've been down to Tamaki Drive 5 times lately and not seen any of the America's Cup boats.

[@airflownztravel]

Stu, they do not have a timetable! Usually between 10 and 4 but they have been out at 7.30 and back by 1. Webcam at the Viaduct can assist but the AM Team Base is just off screen. Mike

[@stubrown3575]

I look forward to seeing these boats, they look spectacular on the clips. Many thanks.

Michael, yes Sir! Mike

[@scamauney]

Howdy! Any signs of new Magic? or is that it??

[@airflownztravel]

Hi Scott, boat 2 is in the shed at Base and due on the water next week. Meanwhile boat 1 has been plastic wrapped and being stored out front. Mike

[@scamauney]

@@airflownztravel Hope they got the new crew positions figured out :)

[@airflownztravel]

Scott, will show you soon! Mike

[@suttonem48]

All very impressive on a flat deck in a 10 knot breeze , but how would they fare in a 3 metre swell in the open waters ? Even Port Philip Bay !

[@airflownztravel]

Marc, if you had a 3mtr swell the wind would be well over the limit, Mike

[@robertstewart302]

Defiant has always been a jinx name for a boat

[@airflownztravel]

Robert, she has been decommissioned, wrapped in plastic and in storage outside at Base. What does Patriot, next yacht, hold out for? Mike

[@AirJKB13]

Why does it say defiant?

[@Designsecrets]

ahhhhhhhh, I was wondering how those side things would go in a turn, especially with another boat around them....as that looked like it could slice another boat open.......but nope, on a turn they go into the water.

[@airflownztravel]

Shaun, if you view my other videos you will see the turns can be very quick and sharp, Mike

[@kajill1]

There always seems to be more spray kicking up from magic then the other boats in there videos I hope that is a good thing

[@airflownztravel]

K1, time will tell! Mike

[@11calman]

I would say that "Defiant" can most probably go half a Knot faster when they learn how to use the Foils better (To reduce the drag) It seems that they have slightly more speed Plus the turns are smarter What would you say "AirflowNZ-Travel

[@airflownztravel]

Gib, I am still a no comment man, but they did look smooth today! Mike

[@pfied765]

are these boats designed to tack or gybe?

[@xerxis100]

huh? both of course

[@Invisty]

yes

[@skyak4493]

You are seeing both. They look the same because the boat speed is so much faster than wind speed.

[@pfied765]

@@skyak4493 Thanks for your reply. I should have been more specific. When heading to an upwind mark will it be faster for an AC75to gybe like a multi-hull or tack like a yacht?

[@skyak4493]

@@pfied765 The fastest way around the upwind mark is neither a tack or a gybe. If you watch the video there are maneuvers where the boat turns 90 degrees or more with no visible change in sail or foil arm -those are upwind mark simulations. Aim high and tight of the mark at about a 45 to true win, veer off 90 around it and head down -sails continuously under pressure. If they miss the mark and pass under they need to turn 180 through the wind, switch sides of both sails and foils. I don't think I have seen that done yet but I am sure they are looking for tactics that could force their opponent to miss the mark.

[@gilbertanthonyperea5236]

Can't wait to add a pair foils to by sabot.

[@airflownztravel]

Gilbert, you will need a couple of support boats! Mike

[@MichaelOZimmermannJCDECS]

I honestly cannot see these lovely "flyers" to sail well in the southern ocean's rough conditions... Maybe the tech is going to prove me wrong.

[@airflownztravel]

Michael, rough conditions mean wind which would be outside sailing limits, Mike

[@Robinlarsson83]

These are America's Cup yachts, inshore matchrace yachts basically, not offshore/ocean racers for races like The Ocean Race or Vendee Globe. But, the IMOCA 60s (single-handed /short-handed ocean racing yachts) for example isn't that far behind in terms of foiling these days. They don't fly completely out of the water, they still have "normal" canting keels and are built a bit heavier than the AC75s

[@airflownztravel]

Vijil, how would you allow spectators to view? Mike

[@glenscannell1215]

A few jibes and a few tacks. Hull never touched

[@airflownztravel]

Glen, what you would call smooth! Mike

[@hakapik683]

I bet they, on the boat, just once want to go for a nice sail without those 2 friggin powerboats following them!

[@airflownztravel]

Hakapick, they are needed in case of mishap, Mike

Those foils are at least 5 metres wide

Not quite, rules allow them to be up to 4m from tip to tip.

當年美洲杯决赛在新西兰舉行，新西兰隊對美国甲骨文隊，新西兰先勝五場，以为勝利在望，但最后以六比五败给美国，结果新西兰隊变為過街老鼠，全隊解散，事后傳言美国對新西兰政府打压，此杯一定要回美国，這是小国悲哀，很多新西兰人從此拒绝帆船賽事。

Kamshu, New Zealanders are still excited by the America’s Cup and look forward to holding on to the Old Mug! Mike

[@peterrose8944]

My Morris Minor goes faster than these so-called yachts. America's Cup has been hijacked by zombies.

[@11calman]

That's because "the Giving mum" was driving mate

[@dyrlegeatgmail]

Yeah, but you need to start an engine

[@chrishemsworth5625]

Would a Morris Minor go that fast without falling to bits?

[@c.s.thorogood203]

I guess Spinnakers and Genakers are a thing of the past now.

[@airflownztravel]

CST, they all have a CodeO huge headsail which I have yet to see, Mike

[@skyak4493]

There is no "downwind" apparent when you sail this fast.
