El presente proyecto se enfoca hacia las formulas ORC, FAST 40+ e IRC, en ese orden de importancia en cuanto a las decisiones de diseño.
La elección de variables que afectan la performance efectiva frente al rating es diferente según la fórmula elegida. El desplazamiento, calado, estabilidad, materiales, distribución de áreas y perímetros en las velas, etc., variaría según el caso, en formas y cantidades sutiles pero significativas.
La directiva fue, sin perder de vista aquellas fórmulas de medición y el presupuesto disponible, lograr el barco más rápido, simple y fácil posible.
Para poder tener margen de cambios en un futuro (principalmente variaciones de desplazamiento, trimado y estabilidad), es importante una buena base de donde partir, un casco estructuralmente fuerte y liviano que permita un margen alto de lastre. La construcción es con fibras unidireccionales y bidireccionales, consolidando con resina epoxi, vacío y post curado a temperatura. Se utilizo carbono unidireccional en las zonas permitidas bajo la ORC (entre el 30 y 70% de la eslora), es decir en los bordes de mamparos, planeros y longitudinales, tanto de cubierta como casco. Fuera de esta zona, únicamente se utilizan fibras de E glass, de esta manera no se pierde la clasificación ORC de construcción “cored”, similar al Soto 40 y Mercenario. Este sistema resulta en una baja significativa de los costos, una mejora en el rating y con una ejecución correcta se logran barcos con rigideces apropiadas. La ingeniería está a cargo de PURE DESIGN & ENGINEERING, bajo dirección de Giovanni Belgrano.

Artemis Racing launch their America’s Cup Class Yacht
Artemis Racing, the Swedish challengers for the 35th America’s Cup, launched their America’s Cup Class (ACC) yacht today at a ceremony at their team base in Morgan’s Point, Bermuda. The boat was officially christened Magic Blue by Natalia Törnqvist and was lowered into the water for the very first time in front of a crowd of invited guests and the team’s family, friends, boat builders, designers, sailors and shore crew.
Torbjörn Törnqvist, owner of Artemis Racing, was on hand at the event to see the hard work and thousands of hours of design and build culminate in the launch of the team’s ACC boat and said: “This is a great day. It’s very exciting to see the result of so much hard work in design, engineering and construction finally here. It feels good and the boat looks fabulous.
“We have reached this point after years of work, all starting with the rules. All the teams’ boats might look, to the untrained eye, more or less identical , but under the surface there is a lot of work in design and theory that differentiates them and which has to be tested on computer systems and on the water, so there really are many thousands of hours involved in this, getting us to this point.
“However, now, with less than 100 days to go, we are on the home stretch. The focus goes from design and development to trying to sail the boat the best we can, and extract the maximum from it.
“We feel we have a good boat, but so do the others. We’ve all been keeping an eye on each other so we all know where the strengths of each team are, but I think the conclusion so far is that you cannot predict anything.
”Next to talk about Magic Blue was Artemis Racing Skipper Nathan Outteridge. “It’s very exciting, rolling out the boat today. It’s been a long time coming! We’ve had two development boats over the last couple of years, testing various foils and systems, and what we’ve launched today is the result of everything we’ve learnt. We’ll get to go sailing on it very soon and then we’ll be racing it for real in a few months.
“I’ve been watching the boat come together over the last few months here in Bermuda and as that build takes place, as members of the sailing team, you want to get in, see the boat and help everyone put it together, but we know that’s not really our job. But finally it’s handed over to us today and now it’s our turn to see what it’s capable of. We have a very exciting couple of weeks ahead, finding out what this boat is really capable of, and that’s obviously very exciting.
“Now we have a few months before racing begins so we have to get out there and start pushing the boat, finding out how quick it is, and improving it. It’s not a simple job of just wheeling it out today and racing it – the shore crew and the designers have done an amazing job to give us this craft, but we’re all aware there’s going to be more development to come in the next few months, so the sooner we get it out there the sooner we can create job lists to really start learning about it.”
With the wraps now off Artemis Racing’s boat, that brings to four the number of America’s Cup team ACC boats that have now been launched. Land Rover BAR, ORACLE TEAM USA and Emirates Team New Zealand have all unveiled the incredible foiling catamarans that they will be racing on Bermuda’s Great Sound in May and June 2017, leaving only SoftBank Team Japan and Groupama Team France to show the world what they will be racing in their challenge to win the 35th America’s Cup.

EMIRATES TEAM NEW ZEALAND LAUNCHES THEIR RACE BOAT FOR THE 35th AMERICA’S CUP
Just 100 days out from the first race of the Louis Vuitton America’s Cup Qualifiers, Emirates Team New Zealand accomplishes the most significant milestone of its challenge for the 35th Americas Cup by christening their America’s Cup Class catamaran that will begin racing in Bermuda in May.
In the presence of the team, their families, the Sponsors and the official suppliers, the boat was christened at the Beaumont Street base in Auckland by Tina Symmans – member of the Board of Directors of Emirates Team New Zealand – and blessed by Ngati Whatua.
“This is a really proud day for the team collectively.” said CEO Grant Dalton. “The campaign always just gets real when you launch the actual boat that you hope will be the one to win the America’s Cup back for New Zealand. It’s when things get exciting, and despite the long hard hours everyone has been putting in there is definitely an added edge to the team now this is in the water.”
The AC Class catamaran, which is 15 meters long (49.2 feet) and has a 25-metre wing, is the result of the team working six- and seven-day weeks since July last year. All the boat’s components were built in New Zealand involving works at Southern Spars, Cookson Boats and C Tech, with the meticulous fit out process being done at the team base since prior to Christmas.
The rule for the America’s Cup Class required certain elements of the boats to be one design (hulls, beams, central pod and wing shape), so designers were mainly focused on control systems and daggerboards where the Protocol allows more flexibility. Even if the AC Class catamarans are 20-feet shorter and have a 15-metres smaller wing than the AC72s, they are expected to be around 20% faster around the race track than in 2013 in San Francisco.
“The guys have just been working so incredibly hard to get to this point. Some guys have been working 12+ hour days everyday without a day off since the 3rd of January. The fact we are the first team to go sailing on the race boat, considering how late we were compared to the other teams is an unbelievable testament to the drive, focus and determination this very special team has collectively.” said Shore Team Manager Sean Regan.
“There is a true belief that this team can take on the five other Goliath’s and win this thing.”
Although not the most significant, but certainly the most evident innovation of the Emirates Team New Zealand racing boat is represented by the cycling grinding system the team is using to produce the energy to power the hydraulic systems throughout the boat.
Emirates Team New Zealand Design Coordinator Dan Bernasconi:
“When we sat down to think about the overall design of this boat three years ago the benefits of cycling opposed to regular grinding were obvious, but certainly not without issues and difficulty with functionality, and this is what we have been working incredibly hard on overcoming for the past three years.”
Bernasconi continues: “Winning the next America’s Cup is all about maintaining a stable flight on the entire race course and that’s the reason why this boat contains some of the most innovative and powerful technology ever used in this competition in its systems, electronics, hydraulics and foil designs.”
The emphasis of the campaign now moves from inside the confines of the boat shed to the open water of the Hauraki Gulf, led by Skipper and Sailing Team Director Glenn Ashby.
“It’s been a challenge to get to this point, and the first sailing has been a very special moment for the entire team.” said Ashby. “The next few months of sailing and development with our race boat will be some of the most important in this America’s Cup. We’ll do a month of intensive testing here in Auckland then we will suspend the test programme and move to Bermuda where we will resume our training until racing starts, on May 26th.”
“In the 30-year history of Emirates Team New Zealand it has always been at the forefront of international sailing. From its beginning with Plastic Fantastic in 1987 to the introduction of foils in San Francisco the team has always reshaped the America’s Cup and the boat we are christening today is introducing revolutionary concepts once again.” concluded Grant Dalton.
“I wish to thank the Sponsors and the official suppliers that have believed once again in our challenge, but I also want to congratulate all the team, and in particular shore and design teams, who have worked relentlessly for months, allowing us to comply with the deadlines we had set.”
The AC Class catamaran in numbers:
2332-2432 kg: boat weight
60 meters: optical fibres
49.2 feet: hull length
25 meters: height of wing above water
over 46 knots: top speed
6: crew members
87.5 kg: average crew weight
90: Emirates Team New Zealand’s members
