The New York Yacht Club American Magic rolled out its new AC75, named 'Patriot' for the 37th America's Cup Competition in Barcelona, Spain. The deck layout places the helms and trimmers side by side and well forward.

The boat has many design features and quirks, including recumbent cyclors facing aft and sculpted, almost harlequin-style foils blended into a sharp stubby bulb with an aggressive point.

The team completed a 7.5 nautical mile tow test and set the MN2-1 mainsail and J3-1 jib.

As the sailing world eagerly awaits the Louis Vuitton 37th America's Cup, the intensity of the competition is only increasing. With four teams revealing their newly-designed AC75s, it's clear that each team has found unique solutions to the same questions, and the stakes have never been higher.

Design teams have been working tirelessly to deliver their best and latest thinking, while electronics and mechatronics engineers have been hard at work producing the control and power-delivery systems that will define each team’s campaign. And as the competition heats up, the teams have revealed some of their secrets.

With three teams already sailing, it's clear that fast-flight is being achieved by a combination of Barcelona-specific hull design and clever-thinking on controls. While Emirates Team New Zealand and Luna Rossa Prada Pirelli are only showing a fraction of their potential, Alinghi Red Bull Racing has everyone sitting up and taking notice with their full-span bespoke foils, which are having an enormous effect on performance.

The differences in hull design and bustle treatment are more nuanced. While it's easy to say that Emirates Team New Zealand and Luna Rossa Prada Pirelli share a similar progressive thinking, INEOS Britannia is also a contender with their own unique design. However, Alinghi Red Bull Racing has thrown a spanner in the works with their chine on the bow and full-length, considerable bustle leading to the stern.

All the teams have gone for T-section shapes at the stern run-off, but it's in the bow area where the differences are most marked. INEOS Britannia boasts real volume in their in-built, immediately voluminous bustle, while the Italians and Kiwis have aggressively flared bow profiles back to the foil arm boxes.

The deck area is also a key consideration. For anyone who has seen an overlaid flow diagram of an AC75, the biggest disturbance air passing over the yacht is at deck level, and it's here where designers and technicians have worked the hardest. The Italians have a beautifully contoured naked carbon approach, molding the side pods evenly into the deck and aft off the transom. Emirates Team New Zealand does the same with a raised ellipse stern that screams aero.

The INEOS Britannia base opened its shutters just after 5 am on Saturday, revealing the latest AC75 to be unveiled for the Louis Vuitton 37th America's Cup. The boat, codenamed RB3 for the past two-and-a-half years, is a sight to behold with its stunning, all-business paint job that accentuates the hull form in a way that tricks the eye.

The design and build of the boat represent the very best in innovation and detail, with a hull form that has been the talk of the town since its reveal. The British have gone for a step-up from their prototype boat 'T6', featuring a voluminous, integrated bustle in the bow with a small chine leading back along the keel-line to a razor-sharp edged lower bustle that stops a few feet from the stern.

The stern gantry is also a sight to see, with its beautifully sculpted design that screams Formula 1. The almost dead-flat stern run-off is unlikely to be touching the water in flight, which is the thinking, at least. The area that has been of much interest in this Cup cycle is the aero moulding of the deck, and here INEOS Britannia seems to have aced it.

The deck run-off aft is highly aero optimised, similar in form to both Emirates Team New Zealand and Luna Rossa Prada Pirelli, but with perhaps slightly more 'tunnel'. The cyclor pods end with a gradual pinch that flows all the way to the transom, and the four pods either side look to be a big nod to aero. Up on the bow, there is considerable moulding that appears drop-nosed in form, undoubtedly the result of endless hours in simulations to create the perfect flow into the jibs.

Overall, the RB3 is a masterpiece in design and innovation, and British fans are hopeful it will give them the best chance of winning the Louis Vuitton 37th America's Cup in 173 years.

Alinghi Red Bull Racing Base has officially presented its race yacht, BoatOne, in a grand ceremony that featured a human tower constructed by the traditional Castellers. The milestone marks a significant shift to the final competition phase of the campaign with the official opening of the Louis Vuitton 37th America’s Cup just a little more than four months away.

The christening ceremony took place at the dockside where BoatOne was formally introduced to the world. Chiara Bertarelli, the designated honouree, cracked the bottle of Champagne across the bow, marking the beginning of a new chapter in the team's journey towards the America's Cup.

The BoatOne is the first vessel that Alinghi Red Bull Racing Base has designed and built together. Team members watched with collective pride as the racing machine was craned into the water for its first contact with the sea and some initial systems checks.

“This is the most amazing thing with a boat like this,” said Principal Designer Marcelino Botin. “It's the result of many people bringing their skills, expertise, and passion to reach a result that reflects the team's expectation.”

While it was a day to soak in pride, there was also the acknowledgement that there is much work ahead. “Launching the boat marks the next stage for us, finally sailing BoatOne. The Sailing team will now have to keep up the amazing work done by the designers and boat builders,” said Skipper Arnaud Psarofaghis.

Overall, the boat presentation was a momentous occasion for Alinghi Red Bull Racing Base, marking the end of one phase and the beginning of another. With the launch of BoatOne, the team is now one step closer to realizing its dream of winning the prestigious America's Cup.

If you were wondering why an AC40 was sailing in Belfast Lough in the last few days, here is the answer.

About a week ago, the AC40 arrived in Belfast for the Swedish Women's and Youth America's Cup teams for training in preparation for the Youth and Puig America’s Cup during September/October, running parallel to the 37th America’s Cup in Barcelona.

This foiling monohull was in Belfast with Artemis Technologies, whose CEO is Iain Percy, ex-2000 Finn Olympic Gold medal winner and ex-2005 America’s Cup +39 Challenge skipper.

Percy instructed the team on the AC simulator and explained why using a simulator is so important. Artemis Technologies is supporting the Swedish Challenge which is united under both the Royal Swedish Yacht Club and Gothenburg Royal Yacht Club – said to be a huge boost to the country’s future participation in the America’s Cup.

The AC40 was watched by some Cockle Island Boat Club members who were “thrilled to see these talented sailors honing their skills right here". "Belfast Lough provides the perfect setting for world-class sailing, and we were excited to witness these elite international teams preparing for their challenge", they added.

The city of Cagliari was buzzing with excitement as Luna Rossa Prada Pirelli launched its boat for the 37th America's Cup. The sailing-mad 'Tifosi' - Italian fans of the sport - are hoping that the boat will bring the coveted trophy to the magnificent island of Sardinia.

The boat, which has been meticulously designed, features a see-through, naked, carbon deck moulding that arcs up to the four-man pods either side with the helms positioned just behind the trim team and the 'pain locker' cyclors positioned aft. The foils, which are clearly legacy AC36, are located forward of the mast, and the ram is exquisitely indented and shaped into the hull. The bustle is conservative and looks right, while there is nothing 'out there' in terms of the deck form that looks like a risk. The boat is pure muscle with so much going on below decks, unseen and top-secret IP, that will be delivered by a team that has undoubtedly had one of the best preparations through the last 18 months.

Luna Rossa Prada Pirelli - the new breed of AC75's with a slender bustle running the full length and tapering logically off the bow

The hull form is atypical of the new breed of AC75's with a slender bustle running the full length and tapering logically off the bow. The bow profile is sharp, kicking off the immediate flaring underneath, while on top, it is sculpted and tapering forward as low-profile as possible within the volume rule. The pods are deep with the cyclors able to tuck in, almost unseen, behind the helm and trim teams.

Some 5,000 fans watched the launch on social media, and countless thousands will marvel at the boat with pride, seeing it as a piece of art created by the true artisans of the America's Cup.

Speaking with Ruggi Tita and Marco Gradoni, the excitement is real, elucidated by a boat that can absolutely deliver, while Max Sirena and Checco Bruni looked like kids on Christmas morning - they know this is a reference boat that gives them every chance of going very deep and with plenty of runway to keep developing through the rounds - their calling-card of the Auckland regatta in 2021. 

Luna Rossa Prada Pirelli is deeply rooted in the national identity of Italy and taps into the Italian psyche. The Prada family's support of the America's Cup is infectious, and the 'golden' generation coming through (fast) is something so exciting, real and tangible. Fusing experience with raw talent is something that the management knows they have to manage, but there's a deep awareness in the team that they have something very special - a generational talent in Gradoni and Tita that could well define the America's Cup for decades to come.

Emirates Team New Zealand's new AC75 race boat has emerged from its building facility after an intensive 10-month programme. The America's Cup boat was wheeled out to prepare for its launch and commissioning phase in Auckland this month.

The team's COO, Kevin Shoebridge, said that it was a significant moment for any team when their race boat emerged from the shed and saw the light of day. He added that these moments were the most revealing of any campaign, giving an indication of the team's design path.

The boat was transported from the North Shore build facility to the Wynyard Point base under the cover of darkness, where an intensive fit-out program was undertaken. Shoebridge said that the team had the day on the calendar for a long time, and it was critical to hit these important milestones.

The team is now preparing for the boat's naming ceremony next week. Shoebridge acknowledged the team's hard work, dedication, and commitment, but also noted that they still have a mountain to climb over the next seven months to defend the America's Cup in October successfully.

Despite the immense secrecy surrounding America's Cup campaigns, Shoebridge said that there comes a time when teams need to show some of their cards. While this boat's launch reveals only a portion of the team's designs, it indicates the team's design path and the boat's commissioning and the first sail will reveal more about the team's progress.

Meanwhile, the America’s Cup Barcelona 2024 will be launched in Ireland later this month by the Spanish Tourism Office with a special presentation in Dublin.

Emirates Team New Zealand sailed accurately and consistently to win the America's Cup Preliminary Regatta in Jeddah, Saudi Arabia. They aced the Grand Final from start to finish, while Luna Rossa Prada Pirelli secured their spot in the Grand Final with another brilliant win in Race 7. The Closing Ceremony marked the end of the regatta, but it opened up a world-class venue for high-performance sailing that is both ambitious and visionary in its dedication to the sport.

Tom Slingsby, Skipper of NYYC American Magic, was really impressed with the event. He praised the hospitality, sailing, and venue, and believed that high-level events could come here in the future. Sir Ben Ainslie, Team Principle of INEOS Britannia, also echoed Tom's words and said that it was a phenomenal event with brilliant conditions. The hosts were truly wonderful and provided a better reception for the event. 

On the water, the fleet of AC40s executed the first two races of the day to decide the final spot in the Grand Final Match Race shoot out. Emirates Team New Zealand had already secured their place with another two wins and one second place. The Kiwis, however, weren't playing it safe. They seemed determined to stamp their mark on this Preliminary Regatta, garnering valuable race-craft and boat trim data in the conditions. 

For Luna Rossa Prada Pirelli, the Italians had issues with the boat's electronics suffering in the heat of the Red Sea. They entered the Match Race Final start-box late which gave the upper hand to Emirates Team New Zealand early on. The Kiwis capitalised on this to lead off the start line, but all around the course, it was desperately close until the very final windward mark. On a bear-away, the Italians got high, and with the rudder exiting the water, a nose-dive splashdown put paid to their race.

Emirates Team New Zealand capitalised on the situation, with Peter Burling, Nathan Outteridge, Blair Tuke and Andy Maloney making no mistakes on the downwind leg to cross the finish line and secure a popular regatta win. They made it count when it mattered most, kept the pressure on and the intensity high, and proved that this tight-knit group of talented sailors can handle the white-hot pressure of America's Cup racing.

Speaking afterwards, Peter Burling said; “Another awesome day of sailing. I feel like we made our lives a little bit harder than we needed to in that last race, but we've been sailing so well all week, haven't done too many things wrong and we're super happy to come away with the win here in Jeddah… It has been awesome here and a great showcase for our sport. To have a couple of breezy days here, it's been amazing.” 

Blair Tuke, Trimmer on Emirates Team New Zealand, summed up the regatta saying: “The last two days have shown what the AC40 class can be like, and we've enjoyed the close racing, beautiful conditions here, and it has been a great advertisement for our sport.” 

For Ruggero Tita, helmsman on Luna Rossa Prada Pirelli, the regatta was a super good experience, and they were happy about the result. But seeing the possibility of winning so close, they regretted not doing more.

America's Cup Preliminary Regatta Jeddah Results

With NYYC American topping the final series standings after a simply stunning day at Vilanova i La Geltrú where they took their chances, front-ran like demons and sailed incredibly smoothly, it was all-on for the Match Race Grand Final against Emirates Team New Zealand. The Kiwis had been the team to beat all regatta. Their speed and execution of manoeuvres were widely viewed as the blueprint for AC40 sailing, and in foiling conditions, these two outstanding syndicates of the 37th America’s Cup would have been hard to split.

Unfortunately, with the seconds ticking down on the start, the wind shut down, and the first Emirates Team New Zealand splashed down to displacement, quickly followed by NYYC American Magic. Indeed, the Kiwis struggled even to start correctly, copping a number of penalties, but as both boats headed upwind, the battle was against the clock.

With a ten-minute time limit to reach the first gate and with the crews desperately trying every trick to try and coax their boat up on the foils, speeds dropped to around 5-7 knots, and the flow wouldn’t stick.

Having come into the final day of the first Preliminary Regatta of the 37th America’s Cup in Vilanova i La Geltrú sitting in fifth place, it was an outside bet at best that NYYC American Magic could climb the leaderboard and challenge for a spot in the Match Race Grand Final

The only option for the Race Committee was to abandon the Match Race Grand Final and thereby award the first Preliminary Regatta of the 37th America’s Cup to New York Yacht Club American Magic.

The 37th America's Cup cycle experienced a delay due to a thunderstorm that swept past Vilanova i La Geltrú, the first Preliminary Regatta of The 37th America’s Cup.

The storm soaked the AC40 fleet and deprived the area of wind, compelling the Race Director to cancel sailing for the day.

Emirates Team New Zealand helmsman Nathan Outteridge agreed with the decision, stating, "It was good to give racing a chance. We all want to be here and we all want to race. It would have been nice if the weather was better."

Outteridge described the conditions as "pretty wet" and said that the wind was only 4 or 5 knots by the time they got going. Iain Murray realized that it wasn't worth the risk and got the boats back to the dock after about 10 minutes.

Despite the setback, everyone anticipates tomorrow's racing, which is scheduled to take place between 15:30-17:30 local time / 01:30-03:30 NZT and is expected to be dryer. You can watch the race live or on demand on the America's Cup YouTube channel
