America’s Cup boats: 8 facts about the AC75 and why they’re unique

• Toby Heppell
• August 20, 2024

The America's Cup boats to be used on the 2024 edition of the event are immensely complicated high tech bits of kit. They might be officially sailing craft but they behave in some remarkable ways

The AC75 is the class of boat that takes part in the America’s Cup and are arguably the most radical boats the compeition has ever seen.  This type of America’s Cup boat was first used in the 2021 America’s Cup so this is the second event in which these boats have been used.  

The America’s Cup is, fundamentally, a design competition, and successive America’s Cups have featured the most extreme yachts yet – for their time – ever since the first race in 1851.

However, the foiling boats we have seen in the last four editions of America’s Cup racing (the AC72 and AC50 catamarans, and now the AC75 monohulls) do represent a new direction for the highest level of sailing.

There are plenty who argue that this technology is so far beyond the bounds of what most people consider sailing as to be an entirely different sport. Equally, there are those who believe this is simply a continuation of the development that the America’s Cup has always pushed to the fore, from Bermudan rigs, to composite materials, winged keels, and everything in between.

Good arguments can be made either way and foiling in the world’s oldest sporting trophy will always be a subjective and controversial topic. But one thing is certain: the current America’s Cup boats, the AC75s, are unlike anything seen before and are showcasing to the world just what is possible under sail power alone.

1 Unimaginable speed

Topping the 50-knot barrier used to be the preserve of extreme speed record craft and kiteboarders. A World Speed Sailing Record was set in 2009 of 51.36 knots by Alain Thebault in his early foiling trimaran, Hydroptere , and was bested in 2010 by kite boarder, Alexandre Caizergues who managed 54.10 knots.

Only one craft has ever topped 60-knots, the asymmetric Vestas Sail Rocket 2 , which was designed for straight line speed only and could no more get around an America’s Cup course than cross an ocean. Such records are set by sailing an average speed over the course of 500m, usually over a perfectly straight, flat course in optimum conditions.

America’s Cup class yachts, designed to sail windward/leeward courses around marks, are now hitting speeds that just over a decade ago were the preserve of specialist record attempts, while mid-race. American Magic has been recorded doing 53.31 knots on their first version of the AC75 class, Patriot.

Perhaps even more impressive, in the right conditions when racing we have seen some boats managing 40 knots of boatspeed upwind in around 17 knots of wind. That is simply unheard of in performance terms and almost unimaginable just three or so years ago.

WATCH: Will the USA’s Radical America’s Cup Design Choices Pay Off?

American Magic’s new AC75, Patriot, has garnered significant attention due to its unique approach. While all the teams are bound…

2 A storm onboard the AC75

Related to the speeds the boats are sailing through the water, particularly upwind, is the wind speeds the sailors will feel on deck.

When sailing, the forward motion affects the wind we experience onboard, known as apparent wind. The oft’ trotted out explanation of how apparent wind works is to imagine driving your car at 50mph. Roll down the window and stick your hand out of it and there will be 50mph of wind hitting your hand from the direction your car is travelling.

So when an AC75 is sailing upwind in 18 knots of breeze at a boatspeed of 40 knots, the crew on deck will be experiencing 40 knots of wind over the decks plus a percentage of the true wind speed – depending on their angle to the wind.

The AC75 crews might be sailing in only 18 knots of breeze – what would feel like a decent summer breeze on any other boat – but they experience winds of around 50 knots.

To put that into context, that is a storm force 10 on the Beaufort scale!

3 Righting moment changes

The single most radical development of the AC75 is to take a 75ft ‘keelboat’, but put no keel on it whatsoever.

When the then America’s Cup Defender and the Challenger of Record, Emirates Team New Zealand and Luna Rossa Prada Pirelli respectively, announced that the 36th America’s Cup (to be held in 2021) would be sailed in 75ft monohulls, conventional wisdom had it that the boats would look something like a TP52 or a Maxi72 – both impressively high performance keelboats.

By doing away with the keel entirely, the design is now like nothing we have ever seen, particularly when it comes to how dynamic the power transition is between foiling and not foiling.

The boats are designed to foil on the leeward foil, with the windward one raised to help increase righting moment: to help balance the boat. This means that when the AC75 is not foiling they are extremely tippy – much more so than most other boats of the same size.

Essentially, when the wind catches the sails, the boat wants to fall over as there is too much sail area for the amount of weight underneath the boat – something a lead keel usually counters on a yacht or keelboat.

Once the boat is up and on the foils, however, that all changes, as everything to windward of the single foil in the water balances the sails. That means, the hull, the crew weight, the sail and rig weight, and the windward foil, all work to counter the sails.

What all this means is that the boats go from being extremely tippy, to hugely powerful in just the few seconds it takes to get up on the foil. “The [AC75s] are really very tippy pre-foiling and then they go through the transition where they will need to build significant power. Then immediately [once they lift off] you have more stability than, well, take your pick, but certainly more righting moment than something like a Volvo 70 with a big canting keel.

“That change all happens in a very short space of time,” explained Burns Fallow of North Sails, who was one of the team who developed the soft wing concept back when the concept was revealed.

4 ‘Cyclors’ return to power America’s Cup boats

Bak in 2017 Emirates Team New Zealand stormed to America’s Cup victory in an AC50 foiling catamaran which was, by some margin, quicker than any of the other teams.

The most glaring difference was their use of pedal grinders to produce power rather than traditional pedestal arm grinders. ETNZ’s sci-fi style term for their grinders was ‘cyclors’, cyclist sailors.

The idea had actually been tried before in the America’s Cup; Pelle Petterson used pedal grinders on the 12-metre Sverige in 1977. But ETNZ’s set-up now was very different: here it was part of a linked chain of innovations, the most obvious emblem of a radical approach.

One obvious benefit was the greater power output from using legs to pedal, but beyond this it left cyclists’ hands free and allowed the team to use a highly sophisticated system of fingertip control systems, and thus to use faster, less stable foils, and then to divide up crew roles so ETNZ could be sailed in a different way.

When the AC75 was first introduced in 2021, Cyclors were specifically banned by the class rule. However, with a reduction of crew numbers from 11 to 8 in the second AC75 class rule – in use for the 2024 America’s Cup – cyclors are now allowed once again and all teams look set to be using pedal power onboard.

5 America’s Cup boats may not be heading where they point

With the AC75 sailing on its foil, drag is dramatically reduced, vast amounts of power can be generated and so speeds rapidly increase. But the foils can serve another purpose too.

In order to be able to lift each foil out of the water, the foil arms must be able to be raised and lowered. Hence the foil wings, which sit at the bottom of the foil arms (and are usually a T or Y shape), do not always sit perpendicular to the water surface and the AC75s often sail with them canted over to something nearer 45º to the surface.

The further out the leeward foil arm is canted – essentially more raised – the closer the AC75 flies to surface and, crucially, the more righting moment is generated as the hull and rest of the boat gets further from the lifting surface of the foil.

There is another positive to this: as the lifting foil is angled, it produces lift to windward, which can force the boat more towards the wind than the angle it is sailing.

Due to this negative leeway (as it is known when a foil creates lift to windward) the boat can be pointing at a compass heading of say 180º but in fact will be sailing at eg 177º as the foil pushes the boat sideways and to weather, essentially sailing to windward somewhat diagonally.

6 The foils are heavy. Very heavy.

As the foils work to provide stability to the boat (when it is stationary both foils are dropped all the way down to stop it tipping over) and to provide massive amounts of righting moment, they are incredibly heavy.

A pair of foil wings and flaps (excluding the one-design foil arm which attaches them to the boat and lifts them up and down) weigh 1842kg. To put that into perspective, the entire boat itself with all equipment (but without the crew) weighs between 6200kg and 6160kg. So the foil wings at the base of the foil arms are nearly ⅓ of the total weight of the boat.

It is partly due to this that you will see some teams with bulbs on their foils. If you decide to go for a skinny foil wing (which would be low drag and so faster) then there will not be enough volume to cram sufficient material in to make the foil weigh enough. So some teams have decided to add a bulb in order to make it weigh enough but to also keep a less draggy, slimmer foil shape.

7 Sails can invert at the head

As with everything on the AC75, the mainsail was a relatively new concept when the boat was first announced. It consists of two mainsails which are attached to both corners of a D-shaped mast tube. This has the effect of creating a profile similar to a wing.

It is well established that solid wing sails are more efficient at generating power than a soft sail and for this reason solid wings were used in both the America’s Cup in 2013 and 2017. But there are drawbacks with a wing: they cannot be lowered if something goes wrong and require a significant amount of manpower and a crane to put it on or take it off a boat.

One reason a wing makes for such a powerful sail is that the shape can be manipulated from top to bottom fairly easily with the right controls. With the AC75 the designers wanted a sail that could have some of this manipulation, produce similar power but could also be dropped while out on the water. The twin skin, ‘soft wing’ is what they came up with for this class of America’s Cup boat.

In addition to the usual sail controls, within the rules, the teams are allowed to develop systems for controlling the top few metres of the mainsail and the bottom few metres.

What this means is that the teams are able to manipulate their mainsail in a number of different ways to develop power and control where that power is produced in the sail. But it also means that they have the ability to invert the head of the sail.

Doing this effectively means ‘tacking’ the top of the sail while the rest of the sail is in its usual shape. The advantage here is that instead of trying to tip the boat to leeward, the very top of the sail will be trying to push the boat upright and so creating even more righting moment. The disadvantage is that it would come at the cost of increased aerodynamic drag.

We know that a number of America’s Cup teams are able to do this, though whether it is effective is another question and it is very hard to spot this technique being used while the boats are racing at lightning speeds.

8 America’s Cup meets F1

A new America’s Cup boat is a vastly complex bit of kit. Each team has incredibly powerful Computational Fluid Dynamics (CFD) software packages and simulators in order to try to understand the various gains and losses.

To make these simulators and computer projections as accurate as possible each team has been getting as much data as they can over their three year development cycle.

In the case of this America’s Cup it does seem the development process is genuinely getting closer to Formula 1 (albeit with smaller budgets than a modern F1 team has behind them).

INEOS Britannia have been work alongside the all powerful Mercedes F1 team (both of who are backed by INEOS) and have been open about how much this has helped their development process and after a relatively small amount of collaboration in 2021 the British team and Mercedes have created a much tighter relationship for the 2024 America’s Cup .

But the British team is not alone. When two-time America’s Cup winner, Alinghi announced they would be coming back to the event after some years on the sidelines, they also announced their own tie-in with current F1 World Champions, Red Bull Racing, to for Alinghi Red Bull Racing .

“It’s really similar to F1,” explains Mercedes Applied Science Principal Engineer Thomas Batch who has 11 F1 titles to his name and is was with INEOS in Auckland 2021. “Certainly in this campaign the technology is close to what we have in F1.

“In terms of raw sensors on the boat you are probably talking in the 100s but then we take that and we make that into mass channels and additional analysis with computational versions of those channels that we then analyse and get into in more detail. So you are looking at 1000s of plots that we can delve into [per race or training session].

“That level of data analysis and then feedback with the sailors is very similar to working with an [F1] driver.”

Where are they now? 6 famous America's Cup yachts

1851 schooner america’s sad demise.

In 1851, the schooner America , sailing for the New York Yacht Club, beat the Royal Yacht Squadron and laid claim to its 100 Guinea Cup. Thus the America’s Cup was born – what is now the oldest trophy in international sport – earning its name from that first winning yacht rather than the country, though the US did go on to hold the trophy for 100 years.

Where is America's Cup yacht  America now?

The famous America's cup yacht America changed hands – and names – a few times after the first historic race, and then wound up in the American Civil War as a Union ship. She stayed in the military as a training ship for the Navy until 1873, when she was sold to a former Civil War General for $5,000 (about $98,000 today). The general raced, maintained and refitted the boat, but after his death in 1893, she was passed down to his son who lacked interest in the schooner and allowed her to fall into disrepair. Despite being eventually donated back to the Navy, lack of maintenance left her seriously decayed. The nail was driven into the coffin when a major snowstorm caused the shed she was stored in to collapse in 1945, and America was scrapped and burned, bringing the history of one of the most famous sailing yachts of all times to a close.

America ’s legacy lives on to do this day, and there are replicas of the schooner you can sail on to relive the glory of this historic vessel. Climb aboard the 32 metre America 2.0 replica (pictured in the inset above) in Key West (November-April) and New York (May-October), or on a 42 metre replica out in San Diego .

1930 Shamrock V is still sailing

J Class yachts are synonymous with the America’s Cup as these slim, graceful beauties once represented the fleet racing for the Cup. The 36.42 metre Shamrock V , commissioned by Sir Thomas Lipton for his fifth and final bid, she was the first J Class yacht to compete for the Cup. The fact that she is the only J Class yacht to be built in wood makes it all the more remarkable that Shamrock V is still floating today.

Where is America's Cup yacht  Shamrock V now?

The Camper & Nicholsons -built J is in pretty perfect condition for a lady of her years. J Class yacht  Shamrock V is currently for sale and looking for a good home. The right owner could sail away on this piece of Cup history just in time as the  J Class yachts make a triumphant return to the America's Cup .

1987 movie star Stars & Stripes still racing

While the film Wind , one of the best boat movies , was inspired by Dennis Conner’s experience competing for the America’s Cup in 1983 on board Liberty , the yacht that was actually used in filming was the 12 Metre type sailing yacht Stars & Stripes 87 . She was called Geronimo in the film, but Stars & Stripes 87 was more than a screen legend. When Conner launched his own campaign, he wanted a culmination of all the Stars & Stripes yachts that came before her, and she was designed to be fast in heavy air. Stars & Stripes 87 wound up being the final 12 metre yacht to win the America’s Cup.

Where is the America's Cup yacht  Stars & Stripes 87 now?

Stars & Stripes 87 can be found in the Caribbean now, able to be sailed with the St Maarten 12 Metre Challenge , giving you a chance to take the helm (if you're lucky) of a real Cup winner.

1988 Stars & Stripes multihulls

Paving the way for the high-performance multihull America's Cup yachts that are redefining the competition is  Stars & Stripes – the catamaran. The first America's Cup multihull yacht, the US team's Stars & Stripes came to be by a cunning interpretation of the Deed of Gift, which only stipulated the challenging yachts be single masted and no more than 90 feet LWL. The result was anything but a true match race, with the much faster, wing-masted multihull Stars & Stripes winning the Cup in 1988.

Where are the America's Cup multihull yachts Stars & Stripes now?

Two versions of the multihull Stars & Stripes were built, a soft sail (S1) and a wing-masted yacht (H3). Stars & Stripes (S1) was acquired by American entrepreneur Steve Fossett and used to set speed records around the world before being sold in 2017 to Key Lime Sailing Club and Cottages in Key Largo, where she is used for day charters and racing. The actual Cup player, Stars & Stripes (H3) was bought by Mark Reece in Naples, Florida and was used for sailing charter trips, but her current status is unconfirmed.

1994 Stars & Stripes once used as a training yacht by Oracle Team USA

America’s Cup yacht Stars & Stripes (sail number 34) is probably most famous for not winning a Cup. It wasn’t because she didn’t perform under pressure, but because she never got the chance. While the 24 metre yacht, designed by David Peddic and built in 1994 by Goetz Boat Works, won the right to defend the Cup, Dennis Conner chose Young America (US 36) over Stars & Stripes . The new choice was no match for Team New Zealand’s Black Magic , which beat out Team Dennis Conner four times in a row.

Where is America's Cup yachts Stars & Stripes (US 34) now?

Famed America’s Cup Stars & Stripes (US 34) is earning a chance to prove herself on the racecourse yet again. She sails out of Chicago, racing against Abracadabra (US 54). After failing to win the Cup in 2000, this iteration of Abracadabra was bought by Larry Ellison, who used her as a training boat for his Oracle Team USA.

2003 USA 76 still sailing in San Francisco Bay

Sailed by the US challenging team in preparations for the 2003 America’s Cup in Auckland, New Zealand, USA 76 never made it to the Cup, but she came quite close. Making it to the Louis Vuitton America’s Cup final, USA 76 faced the Swiss Team Alinghi but didn’t come out on top. So the US team arranged for a “rematch” against Alinghi, with two races set in San Francisco Bay. While it didn’t change the results of the Cup, this time USA 76 bested the Swiss competitors twice over.

Where is America’s Cup yacht USA 76 now?

Fittingly, USA 76 resides in San Francisco Bay and is available for sailing. Capture the spirit of the most recent America’s Cup that was raced in the natural amphitheatre of the Bay by climbing aboard USA 76 for a racing adventure under the Golden Gate Bridge.

America’s Cup 2024: What are the AC75 boats and how do they work?

The world’s oldest international sports trophy, best yachtsmen and cutting-edge design and technology come together in Barcelona for the 37th edition of the America’s Cup.

Five boats – from Italy, the United States, Britain, Switzerland and France – will spend the coming weeks racing in the Mediterranean waves to decide who will earn the honour of trying to dethrone the mighty Emirates Team New Zealand for the Auld Mug.

As the two-time defender, the Kiwis chose Barcelona’s choppy waters as the venue and helped establish the rules and boat design for this edition. They also get a guaranteed spot in the final, to be held in October.

The results of three years of work and massive investment will now be put to the test.

“It is starting to get serious in a hurry. We are now racing for keeps,” Ben Ainslie, skipper of British team Ineos Britannia, said.

Here is everything we know about the boats – AC75s – that will be racing...

“Because Barcelona is quite a lightwind venue, you don’t actually want to design foils for going at 60 knots. Acceleration and manoeuvrability are more important. So in terms of top speeds I don’t think we will see anything radically different from the top speeds we saw in the last Cup in New Zealand. Somewhere around 50 knots. But these boats would smash the boats from last time if they actually raced. I guess it’s like Formula One cars. The new boats are much faster over a lap, but they gain that time through cornering speed and acceleration rather than on the straights.” – Giles Scott (Head of Sailing, Ineos Britannia)

This is the second iteration of the AC75 after they were also used in New Zealand at the 36th Cup.

The “75” in AC75 stands for 75-feet, the length of the boat. The boats are 16 feet wide.

The AC75 is a “foiling” monohull, which means it has only one hull which lifts up out of the water on hydrofoils - or “flies” - when the wind gets above a certain speed, typically around six knots.

Although the boats look very similar, there are various changes since the last Cup.

The rules have been tweaked partly to improve light-wind performance (frankly, it looked silly when the most technologically-advanced boats in the world fell off their foils in light winds in New Zealand in 2021, bobbing around helplessly) and partly to reduce crew numbers from 11 to eight for cost and performance reasons.

The move to reduce the crew means cycle power is again legalised, and “cyclors”, the hybrid sailor-cyclists introduced by Team New Zealand in Bermuda in 2017, return.

Length: 75 feet

Width: 16 feet

Height: 26.5m from the deck

Weight: 6,200kg

Max crew weight: 700kg

Top speed: 50 knots

Eight-man crews

Crews have been reduced from 11 to eight since the last Cup.

No boat will feature anyone crossing during manoeuvres. That will be the biggest visual change for spectators. Everyone stays where they are, with four sailors on each side of the boat.

The crews sit low in their pods, out of the airstream with only their helmeted heads exposed.

Each team is slightly different in how and where they deploy their eight men, but every team has a helm, a trimmer and two cyclors on either side of their boat.

The British team are unique in that their trimmer-pilots sit at the back of the boat in the aft pods, with the two cyclors between them and the helms in the forward pods.

The cyclors’ role is to provide hydraulic power to the boat’s systems, from the foil arms to the mainsail.

The Americans are outliers in that their cyclors are “recumbent”, meaning they are sitting/lying backwards, facing up towards the sky. This position sacrifices some power - around 10-20 per cent compared to traditional cyclists - but it does free up their hands to perform secondary functions.

But it is likely that on every boat, certainly the British one, the cyclors will all have secondary roles. On Britannia, two of those roles are critical functions but not necessarily sailing-skill oriented (these might be suitable for former rowers who do not have sailing backgrounds). Two you would want to put sailors in there.

F1 crossover

The crossover between America’s Cup and F1 is becoming ever greater. Not for nothing is sailing’s most elite competition becoming known as “F1 on water”.

Carbon-fibre composites, structural analysis, hydraulic systems, control systems, electronics, data analysis, hydrodynamics and aerodynamics are just some of the overlapping areas.

Ineos Britannia have a partnership with Mercedes F1 via joint owners Ineos. The sailing team has offices in Brackley and hundreds of Mercedes staff have been seconded to the sailing project. James Allison is Chief Technical Officer of both teams. Geoff Willis is Technical Director of Mercedes-AMG F1 Applied Science and INEOS Britannia.

Each boat is equipped with a pair of T-foils, on the end of “cant arms”. Around the size of an ironing board, the foils on the AC75 are capable of lifting a seven-tonne boat out of the water.

As in the last Cup, the mainsail is “twin skin”; two membranes held together. Teams are allowed to “endplate”, or seal the mainsail onto the deck of the hull (or platform). This provides performance gains by stopping air flowing under the bottom of the mainsail, which detrimentally reduces the pressure differential between the windward and leeward sides.

The AC75 rudder allows the boat to change pitch, or trim, by providing lift. This change in pitch moves the stern of the boat closer to the ground, which increases the angle of attack on the main foils. The foils provide lift, which moves the entire platform up.

THE AMERICA'S CUP CLASS AC75 BOAT CONCEPT REVEALED

An exciting new era in America’s Cup racing has been unveiled today as the concept for the AC75, the class of boat to be sailed in the 36th America’s Cup is released illustrating a bold and modern vision for high performance fully foiling monohull racing yachts.

The Emirates Team New Zealand and Luna Rossa design teams have spent the last four months evaluating a wide range of monohull concepts. Their goals have been to design a class that will be  challenging and demanding to sail, rewarding the top level of skill for the crews; this concept could become the future of racing and even cruising monohulls beyond the America's Cup.

The AC75 combines extremely high-performance sailing and great match racing with the safety of a boat that can right itself in the event of a capsize. The ground-breaking concept is achieved through the use of twin canting T-foils, ballasted to provide righting-moment when sailing, and roll stability at low speed.

The normal sailing mode sees the leeward foil lowered to provide lift and enable foiling, with the windward foil raised out of the water to maximise the lever-arm of the ballast  and reduce drag . In pre-starts and through manoeuvres, both foils can be lowered to provide extra lift and roll control, also useful in rougher sea conditions and providing a wider window for racing.

Although racing performance has been the cornerstone of the design, consideration has had to be focused on the more practical aspects of the boat in the shed and at the dock, where both foils are canted right under the hull in order to provide natural roll stability and to allow the yacht to fit into a standard marina berth.

An underlying principle has been to provide affordable and sustainable technology ‘trickle down’ to other sailing classes and yachts. Whilst recent America's Cup multihulls have benefitted from the power and control of rigid wing sails, there has been no transfer of this technology to the rigs of other sailing classes. In tandem with the innovations of the foiling system, Emirates Team New Zealand and Luna Rossa are investigating a number of possible innovations for the AC75's rig, with the requirement that the rig need not be craned in and out each day. This research work is ongoing as different concepts are evaluated, and details will be released with the AC75 Class Rule  before March 31st, 2018.

The America's Cup is a match race and creating a class that will provide challenging match racing has been the goal from the start. The AC75 will foil-tack and foil-gybe with only small manoeuvring losses, and given the speed and the ease at which the boats can turn the classic pre-starts of the America's Cup are set to make an exciting comeback.  Sail handling will also become important, with cross-overs to code zero sails in light wind conditions.

A huge number of ideas have been considered in the quest to define a class that will be extremely exciting to sail and provide great match racing, but the final decision was an easy one: the concept being announced was a clear winner, and both teams are eager to be introducing the AC75 for the 36th America's Cup in 2021.

The AC75 class rule will be published by March 31st 2018. 

GRANT DALTON, CEO Emirates Team New Zealand 

“We are really proud to present the concept of the AC75 today. It has been a phenomenal effort by Dan and the guys together with Luna Rossa design team and there is a lot of excitement building around the boat in the development and getting to this point.”

“Our analysis of the performance of the foiling monohulls tells us that once the boat is up and foiling, the boat has the potential to be faster than an AC50 both upwind and downwind.”

“Auckland is in for a  highly competitive summer of racing in 2020 / 2021.”

DAN BERNASCONI, Design Coordinator Emirates Team New Zealand:

“This design process has been new territory for the team, starting with a clean sheet to develop a class - and we've loved it. We wanted to see how far we could push the performance of monohull yachts to create a foiling boat that would be challenging to sail and thrilling to match race. We're really excited about the concept and can't wait to see it on the water..

We think we have achieved these goals - thanks also to the constructive co-operation of Luna Rossa design team - as well as the more practical detail to consider in terms of cost management and logistics of running the boats.”

PATRIZIO BERTELLI, Chairman of Luna Rossa Challenge:

“The choice of a monohull was a fundamental condition for us to be involved again in the America’s Cup. This is not a return to the past, but rather a step towards the future: the concept of the new AC 75 Class, which Emirates Team New Zealand and Luna Rossa design teams have developed together, will open new horizons for racing yachts, which, in the future, may also extend to cruising. It is a modern concept, at the high end of technology and challenging from a sporting point of view, which will deliver competitive and exciting match racing. I would like to thank both design teams for their commitment in achieving, in just four months, the goal which we had established when we challenged”.

MAX SIRENA. Team Director of Luna Rossa Challenge:

  “As a sailor I am very pleased of the concept jointly developed by both design teams: the AC 75 will be an extremely high-performance yacht, challenging to sail, who will require an athletic and very talented crew. Every crew member will have a key role both in the manoeuvres and in racing the boat; the tight crossings and the circling in the pre-starts – which are part of the America’s Cup tradition – will be back on show, but at significant higher speeds. It is a new concept, and I am sure that its development will bring interesting surprises”.
