La revolucionaria vela flexible de North Sails para la 36 America’s Cup

Burns Fallow y Michael Richelsen lideran el equipo de trabajo de North Sails, Emirates Team New Zealand y Luna Rossa para desarrollar el concepto de vela flexible y la Regla de Clase AC75. El North Design Suite, herramienta clave para analizar el monocasco volador con el que se competirá por la 36 America’s Cup.

North Technology Group cuenta con una larga y productiva historia en la America’s Cup. Tanto la velería North Sails como la firma de aparejos Southern Spars han sido fundamentales en el desarrollo de barcos de Copa durante años, más recientemente con la introducción de la revolucionaria tecnología 3Di y los innovadores catamaranes foileadores de ala rígida. El anuncio del nuevo concepto de barco con el que se competirá por la 36 America’s Cup debe mucho del trabajo, los recursos, la experiencia y la creatividad al corazón del Grupo North. North Sails y sus herramientas de diseño han vuelto a ser parte clave para el desarrollo de los monocascos que volarán en Nueva Zelanda en 2021.

El Defender Emirates Team New Zealand y el Challenge of Record Luna Rossa tenían claro que querían crear algo nuevo, emocionante y diferente cuando sugirieron las primeras pinceladas de cómo sería la defensa en Auckland. Para ello, no dudaron en recurrir a North Sails, el indiscutible líder mundial de diseño y fabricación de velas.

Desde el inicio de la colaboración, en septiembre de 2017, los expertos de North Sails Burns Fallow y Michael Richelsen fueron conscientes de que debían implicar el North Design Suite, la serie de programas informáticos utilizados por arquitectos navales, diseñadores y regatistas de todo el mundo. Entre los componentes del Suite, iba a ser determinante para el desarrollo del nuevo concepto el software Membrain©, que equilibra presión de viento, forma de la vela y fuerzas del aparejo.

Según Fallow: “Iniciamos este proyecto en septiembre y no tuvimos mucho tiempo para valorar si esta idea iba a ser viable o no, así que había muchas preguntas esenciales que requerían respuesta. Preguntas como cuál será la diferencia de cargas entre la superficie de barlovento y de sotavento de la vela, cómo trabajará la interacción entre sables y mástil, o cuál será el beneficio aerodinámico de todo esto. E iba a resultar arriesgado dar una respuesta. Informé a Michael (Richelsen) sobre lo que tratábamos de lograr, y apenas dos meses más tarde, tras un exhaustivo desarrollo informático, logramos una versión del Membrain que nos ayudó a responder esas preguntas. Desde entonces, hemos añadido más y más funciones para lograr modelos más perfeccionados. Es uno de los proyectos más emocionantes y progresivos en los que he estado involucrado en mis 30 años con North Sails”.

Membrain se utiliza en paralelo con Flow©, que inicialmente aplica presión de viento al conjunto de velas y aparejo, y devuelve un mapa de presiones, fuerzas y momentos generados sobre los mismos. Membrain utiliza estos resultados de Flow para calcular la deformación virtual de la combinación aparejo/vela como estructura unificada. Este proceso se repite hasta que se consigue un equilibrio estable.

El ingeniero jefe de desarrollo de software en North Sails, Michael Richelsen, explica: “Sabíamos que Membrain iba a resultar clave para llegar a una conclusión para el concepto de barco que buscaban Emirates Team New Zealand y Luna Rossa Challenge. Ajustando variables en diseño de velas y aparejo, podemos utilizar Membrain para refinar y optimizar formas del ala, diseño del mástil, configuración del aparejo y más. Trabajando con análisis de aerodinámica e hidrodinámica para los catamaranes de vela rígida de la anterior Copa (2017), adaptamos Membrain al concepto de vela flexible para crear una simulación para el análisis completo del nuevo barco, cargas, aparejo, velas”.

Rígida, flexible o convencional
El sistema de doble elemento de vela rígida utilizado en las ediciones 34 y 35 de la America’s Cup (2013 y 2017) dio lugar a un nivel inédito de trimado. Un ala dividida en segmentos puede ser configurada con una profundidad mayor que una vela convencional, logrando así una fuerza de sustentación mayor cuando se necesite. En segundo lugar, los brazos de control rígidos pueden forzar la inversión de las secciones superiores, lo que crea un momento de adrizamiento, requerido en condiciones de exceso de potencia, al invertir la fuerza de sustentación. Pero un ala rígida es complicada, cara y poco práctica para la navegación en general.

La vela flexible es un híbrido entre una vela convencional y una rígida. Los pares de sables (uno en cada sección) controlan activamente el twist en el área superior. El control de estos sables puede cambiar la forma de la vela y consecuentemente las prestaciones. Aunque la inversión de sección de una vela flexible no puede ser tan dramática como lo sería en un ala rígida, si es mucho mayor que la de una mayor convencional. Mucho del desarrollo reciente de North Sails en Membrain se ha centrado en modelar la interacción entre pares de sables.

A diferencia de una mayor convencional, un ala rígida no se desventa. La vela flexible conserva esta característica gracias a los pares de sables, por lo que puede liberar potencia mejor que una vela convencional, algo muy beneficioso y aprovechable. Por su parte, la superficie 3Di actúa como esencial receptor de cargas, colaborando con los pares de sables para lograr una vela flexible efectiva.

JB Braun, jefe de diseño e ingeniería en North Sails, explica que las consecuencias de esta investigación trascenderá el nicho de la America’s Cup: “Tras 20 años de investigación y desarollo en diseño de velas convencionales y rígidas, podemos trabajar junto a Emirates Team New Zealand y Luna Rossa Challenge para ayudar a evolucionar nuestro deporte con la nueva regla para la 36 America’s Cup. En un período de tiempo reducido (meses frente a años), hemos trabajado unidos utilizando North Design Suite para guiar la próxima generación de barcos de America’s Cup Class. Como ya comprobamos desde el nacimiento de la tecnología 3Di con Alinghi, que hoy es utilizada tanto en competición como en crucero, los beneficios de este trabajo para el deporte de la vela son enormes”.

INEOS TEAM GB launch challenge for the 2021 America’s Cup

INEOS has formed INEOS Team GB and is making the biggest ever British investment in the America’s Cup in an unprecedented effort to bring the trophy back to Britain for the first time since the competition was established in 1851.

INEOS Team GB has teamed up with Sir Ben Ainslie who will lead the design and build boat programme and skipper the racing yacht.

INEOS Team GB will represent the Royal Yacht Squadron’s affiliated club, Royal Yacht Squadron Racing who issued the challenge to the current holder represented by Emirates Team New Zealand.

Jim Ratcliffe, INEOS chairman, says, The America’s Cup is one of the world’s most competitive yacht races and Britain has never won it, despite founding the competition over 150 years ago. With the team we have assembled, we believe we can get a fully competitive boat to the start line. After that it’s all down to the fine art of sailing. Ben is arguably the best sailor that Britain has ever produced so we should have a fighting chance of success.’

INEOS has formed INEOS Team GB to compete for the trophy and is committed to spending £110 million – the biggest ever British America’s Cup investment – to bring the Cup back to the Britain.

INEOS will use its world class technologies and manufacturing know-how to support Sir Ben Ainslie in developing an internationally competitive boat and give INEOS Team GB the best possible chance of success.

Jim Ratcliffe, founder and chairman of INEOS, says, ‘INEOS has taken on many serious projects in the past but none more exciting than this. We have a first-class team and will do everything we can to bring this trophy back to Britain where it belongs.’

INEOS has partnered with Sir Ben Ainslie and his team to design, build and race the two-boat strategy. The boats will be 75 ft foiling mono-hulls and will use the very best of British technology and boat construction.

Sir Ben is Britain’s most decorated and the world’s most successful Olympic sailor. He was a member of the 2013 America’s Cup winning team and is INEOS Team GB’s Team Principal.

INEOS Team GB’s CEO is America’s Cup legend, Grant Simmer, who has competed in 10 America’s Cups and won four, first as a young navigator aboard Alan Bond’s Australia II, then twice with the Swiss team, Alinghi, and most recently with Oracle Team USA where – along with Ben Ainslie – they fought back from an 8 -1 deficit to win the trophy. INEOS Team GB’s Chief Designer is New Zealander, Nick Holroyd, one of the men responsible for Emirates New Zealand’s Cup winning strategy. . He is joined by British Olympic gold medallist, Giles Scott, who will act as the team’s Tactician.

Sir Ben says, ‘This is an amazing boost for British sport. With this significant commitment from INEOS to fully fund a two boat challenge, Britain now has its best opportunity to bring the America’s Cup back home to Britain where it belongs.’

INEOS Team GB will represent the Royal Yacht Squadron’s affiliated club, Royal Yacht Squadron Racing. The Royal Yacht Squadron is one of the world’s most prestigious yacht clubs and was granted the Royal Ensign by King William IV in 1815.

The history of the America’s Cup started at the Royal Yacht Squadron in 1851 when fifteen of its boats raced and lost to a US yacht called ‘America’ from where the cup eventually got its name.

167 years later and Britain has still not won the trophy. The Royal Yacht Squadron Racing has issued the challenge to their rivals and the current Cup holder, the Royal New Zealand Yacht Squadron.

James Sheldon, the Royal Yacht Squadron Commodore says, ‘The America’s Cup is undoubtedly the most important yachting trophy in the world and we are delighted that Royal Yacht Squadron Racing is supporting INEOS Team GB in its attempt to bring it back home.’

The Cup – affectionately known as the ‘Auld Mug’ – attracts the world’s top sailors and yacht designers and is the world’s oldest sporting trophy. This will be the 36th America’s Cup and will take place in 2021.

Jim Ratcliffe, the founder and chairman of INEOS, adds, ‘With the resources of INEOS, the skill of Sir Ben Ainslie and his team and the experience of the Royal Yacht Squadron, I think INEOS Team GB has a great chance of success in 2021 and I’m looking forward to the challenge.’

36th AMERICA’S CUP CLASS RULE PUBLISHED

The Royal New Zealand Yacht Squadron and Circolo della Vela Sicilia, together with their respective teams Emirates Team New Zealand and the Challenger of Record – Luna Rossa, published the AC75 Class Rule for the 36th America’s Cup today.

The AC75 Class Rule defines the parameters within which teams can design a yacht eligible to compete in the 36th America’s Cup. It regulates all aspects of the boat to ensure fair and exciting racing, whilst leaving plenty of freedom for innovation to flourish.

The development of the Class Rule has been a four-month process led by Emirates Team New Zealand, working together with Luna Rossa Challenge.

“We are pleased to publish the Class Rule on time as per the Protocol. It has been a detailed collaboration with the Challenger of Record on all aspects of the rule, including the one design and supplied parts. We feel we have done a great job containing costs on certain aspects, while leaving the rule open enough for the America’s Cup to continue as the driving force of innovation and technology in sailing,” said Dan Bernasconi, Design Coordinator for Emirates Team New Zealand.

Highlights of the AC75 Class Rule include:

Strict limitations on the number of components that can be built including hulls, masts, rudders, foils and sails, thus encouraging teams to do more R&D in simulation and subsequently less physical construction and testing
Supplied foil arms and cant system to save design time and construction costs
Supplied rigging
One design mast tube
In addition, the ‘soft wing’ mainsail concept that has been developed for the AC75 Class Rule is expected to have a trickle down effect on sailing in the future.

“The AC75 Class Rule sets the parameters for the teams to develop and race the fastest sailing monohull on earth. The rules are the result of a close collaboration and a true partnership between Emirates Team New Zealand and Luna Rossa,” said Martin Fischer, Design Coordinator for Luna Rossa Challenge.

“This marks a definite milestone and a turning point from developing the rule to developing the boat,” said Dan Bernasconi. “Overnight we have to completely change our thinking, from trying to write a fair rule, to doing our best to design the fastest boat within the constraints of the rule. We have to stop thinking about what we intended the rule to mean, and start trying to pick it apart for what the words actually say – and see where there might be room to squeeze some advantage.”

This will be the same for the best minds in yacht design and technology across all of the teams who will begin to reveal their innovations 31 March 2019 when the first AC75 yachts can be launched.​

New York YC and Bella Mente Quantum Racing to Challenge for 36th America’s Cup as American Magic

NEW YORK, N.Y. – The New York Yacht Club and Bella Mente Quantum Racing Association today announced they will compete under the name New York Yacht Club American Magic in their challenge for the 36th America’s Cup, to be held in New Zealand in 2021.

Philip Lotz, Commodore of the New York Yacht Club, said, “America was the first boat to win the America’s Cup in 1851. Magic was the first boat to defend the Cup in 1870. American Magic builds on the legacy of those two yachts, and the name embodies the mission of our campaign, which is to win the Cup and in the process build the foundation for a stronger competitive sailing culture in the United States. The New York Yacht Club is very excited to be part of this campaign and the legacy we are striving to create.”

Over the coming months, American Magic will continue assembling a team of top sailing talent, and best-in-class designers and engineers to best position it to bring the America’s Cup home to the United States and the New York Yacht Club. As it builds its world class team, American Magic will leverage its partnerships with US Sailing and Oakcliff Sailing to develop the next generation of American sailors, reenergize the passion of fans and make the America’s Cup relevant to the broad base of American sailing.

Hap Fauth, CEO of American Magic, said, “On behalf of Doug DeVos, Roger Penske and all the members of our team, it is an honor to represent the New York Yacht Club, its membership and the American yachting community in the 36th America’s Cup as American Magic. Under this proud name, we are focused on creating an America’s Cup culture in American sailing, and with our partnerships, we are engaging with the grassroots to increase the competitiveness of our sailors, and working to engender the kind of excitement the America’s Cup previously enjoyed in the United States. We’re not just racing to bring the Cup back to America, we’re racing to bring American yachting back to the Cup.”

Doug DeVos, Principal of American Magic, said, “As an avid sailor and passionate supporter of the NYYC, I’m thrilled to be a part of such an extraordinary team. Over the years, we have worked hard to promote sailing in the United States and inspire the next generation of sailors to compete at the highest levels of our sport. It’s an honor and privilege to be a part of American Magic’s challenge to bring the America’s Cup back home.”

American Magic’s design team is actively at work planning for the first of two AC75 class boats, and preparing for the publication of the AC75 Class Rule at the end of March. At the same time, the American Magic’s sailing team is currently training in Long Beach, Calif., for the Ficker Cup, which is the qualifier for the Congressional Cup. The team expects to establish its primary base in Newport, R.I., later this spring.

STATEMENT ON LATEST AMERICA’S CUP BASE PLAN
Mar 13 2018

Emirates Team New Zealand today confirmed that they have been presented with another plan for Americas Cup base location and design.

Team boss Grant Dalton said today ” the government came to us with a further plan last week. Its a further iteration of the Ministers plan known as the Hybrid option but is closer to the one designed by Viaduct Harbour Holdings. On the face of it and to the layman’s eye it looks like it could work.

In the limited time we have had to look into the detail we see that there are some problems that need to be addressed.

The latest plan reduces the extension of Halsey St Wharf from 75 metres to 45 which will please Stop Stealing Our Harbour.

But with the reduction of the extension of Halsey wharf, this means the majority of the challenger bases must go onto on Wynyard Wharf.

The Government has successfully negotiated with Stolthoven for the removal of their tanks earlier than was planned. The same sort of negotiation is currently taking place with Bulk Storage Terminals who own the other tanks that would need to be removed. This negotiation needs to be concluded before this plan could be considered viable. We are unsure of the timeframe for those negotiations to be concluded.

The Wynyard Wharf tank removal and remedial work are complex and time consuming. We along, with Government and Council, have concerns about the works timetable and availability of specialist construction resource in an already stretched environment. The government is seeking a second expert opinion on the timetable issue and we support them in doing this.

There is little point in agreeing to a plan that can’t be delivered on time.

David Parker agreed that we would have a permanent Base on Hobson Wharf. He has been forced by Viaduct Harbour Holdings threat to disrupt the resource consent process to back away from that commitment and move our base to the eastern end of Halsey wharf. To be honest I’m a bit pissed off with this but I will live with an equal Base at the eastern end of Halsey Wharf. It’s far enough away from the activities that occur at the Events Center but still allows us to build an innovative interactive public space.We are planning a space where people can get really close to the team while at work and experience the excitement of sailing these amazing boats through simulators and other great technologies.

None of this is ideal but we will continue to work through the challenges in an effort to see the Americas Cup hosted in 2020/21 in Auckland. Its where our home is and where our heart is. Council and Government have their own challenges and we recognize that they are doing their utmost to meet them.

We have a meeting with Challengers in Europe at the end of this month and confirmation of Auckland as a venue and the class rule are eagerly awaited by them.”
