Breaking: Sweden’s Artemis Racing team crashed its AC72 in San Francisco Bay during a practice run on Thursday, May 9. The AC72 is a catamaran: a scrim of netting stretched between twin knifelike hulls, each 72 feet long but only a few feet wide. He sets a course along the northern shore of San Francisco, aiming for a spot halfway between Alcatraz and the bridge.
By the time he gets past Alcatraz, Spithill and crew find themselves in massive chop, a product of the tide and wind working against each other. Turning from an upwind heading to a downwind heading is a basic maneuver in a conventional sailboat. The America won because its owners experimented with novel nautical technologies and spared no expense in building it (some things never change). In the modern era of the Cup, post–World War II, the contest has become a little less of a free-for-all. But the most naked clash of egos and billfolds plays out in the no-limit contests, the so-called deed-of-gift races — anything-goes throwbacks to the old 19th-century rules, triggered when one billionaire decides that he no longer wants to play nice and rejects the limits imposed by a rule. Having won the Cup in the deed-of-gift match, Ellison decided that he wanted to have it both ways for the next contest, the party he would throw in 2013. In 2010, at the age of 30, Spithill became the youngest winning skipper in America’s Cup history. In a nod to at least some tradition, everyone agreed to ban the motorized winches that were used in 2010. The change of the spec from traditional soft-sailed monohulls to the new wingsailed twin hulls came with a media strategy explicitly designed to turn the America’s Cup into a real spectator sport. Still, though there are only four teams, racing the big AC72s promises to be far more exciting than even watching the World Series boats. Splashing down face-first catapults the two hulls upright and momentarily triples the force of gravity. The Oracle race crew starts climbing down to the bottom-most cockpit, where it’s possible to crawl out. It takes 10 minutes to get everyone off the boat and out of harm’s way, during which time the boat is slowly sinking. Turner watches, helpless, as the submerged wing starts sawing against the main body of the boat. That 20 years could have been spent practicing on the bay, engineering subtle mods, and otherwise moving toward the ultimate goal of winning the Cup. As to where his own responsibilities lie — as Spithill’s mentor, as Team Oracle CEO, as a champion of the AC72 — Coutts is more circumspect.
It’s a question that the other teams — Luna Rossa, New Zealand, and Artemis — are asking themselves now. The real unknown, he says, is whether the damage caused by the Oracle crash was, as Coutts argues, an exception, a bad accident compounded by severe tides — or something closer to the norm when an AC72 capsizes in the rough waters of the bay.
INTRO: To keep some of my friends informed (sailors and otherwise), I've been collecting together interesting info about the upcoming America's Cup. However, it was recently suggested to me that some readers of my Small Trimaran Design website might also be interested, so why not post the info for broader interest and readership? I make no promise about anything regular, but if I learn about something potentially interesting to add and can find the time, you might find a few comments about it here. As many will know, the America's Cup started back in 1851, when a fast boat from America challenged all the top boats around southern Britain, for a race around the Isle of Wight, off the coast of England.
Well, the American boat beat them all and won the elaborate silver challenge cup that we now all know. I don't intend to go more thoroughly into the early story than that, as there's plenty of history on line if anyone is interested.
But we've come a LONG way since then and seen LOTS of changes in the boats used—and after a brain storming session in 2010 (in Spain I believe), it was decided that the Cup's future might be doubtful unless something was done to get more sponsors involved and for that to happen, more spectators and public enthusiasm must be garnered.
So the choice was made for a super-size, state-of-the-art, hi-tech multihull that, as for Grand Prix car racing, could offer "thrills and spills" and famous multihull designers Gino Morelli and Pete Melvin were chosen to write up some rules.
Each country involved is permitted to built up to two boats, though not all countries will be able to raise the $50+ million needed to do that. Side story : Everyone knows that the SF Bay area can be VERY rough and gusty, and with the tide ebbing fast against strong winds, the conditions can get very wild for such lightweight machines.
Well, both New Zealand (Team Emirates) and Sweden (Team Artemis) are already sailing their AC72s and Italy (Luna Rossa) will christen a boat any day now. Six other teams had planned to challenge also, but only Team Korea is still a possibility, though there is still no news as to whether their AC72 is even under construction.
But apparently none of these made the deadline; most missing on the financial commitment required. Two further long shots, which had originally expressed interest, were 'Team Synergy' from Russia and the 'Red Maple Racing Team' from Canada (RCYC), but they also failed to raise the necessary funding in time to register their challenge officially.
One very fascinating thing about this America's Cup, compared to all others, is that the committee in charge is fully determined to make this a spectator sport. As Multihulls World did a nice resume of the America's Cup, I do not need to write more than this. Here's the link that says it all—an incredible comeback for sure—and these boats really FLY! Here you will see just HOW close these boats were, even in the final race, with New Zealand taking the all-important start but ultimately, Oracle-USA showing it had found that little extra boat speed to not be beaten. Enjoy it all one final time, and expect to see Australia take over the role of New Zealand in the next one—probably in 2017. Due to a 2 point penalty imposed on the US team (because some crew members illegally added corrective weights in one of their earlier boats), this means that, with one point per race win, the US team ORACLE must now win 11 of the 17 races, whereas New Zealand needs to win only 9. At the moment, the Kiwis have the upper hand with 3 wins to 1 and the US team will need another win, before their wins will even start to count—due to that annoying 2 race penalty. Typically in an Americas Cup final, we see quite some difference in the two final boats and often the end result looks pretty clear after the first 2 races. It appears that for each race, the boats must take turns in crossing the start line on port or on starboard (the latter having the advantage). Both teams are obviously pushing hard and anything can happen at this point—so stay tuned to the race reports on line. Depending on any new choice of boats, we may never see these super high speeds (and associated risks) again — so keep in touch and enjoy this incredible spectacle.
With the preliminary 'Round Robin' rounds over and the NZ Emirates not having lost a race, the 2nd and 3rd placed boats are now competing in the 'semifinals'—the best of 7 races (4 wins). On August 17th, the finals for the Louis Vuitton Cup (and the honor to challenge the Cup owner USA) will start, with NZ racing against the winner of the Semifinals. Before the final Americas Cup competition starts in September, a significant number of youthful foreign-based teams will compete in AC45s to decide who is the best to date. As far as sheer performance, these boats (AC72s) are certainly pretty amazing if the reported figures are to be believed, and there's no reason not to.
The straight line course length for the Vuitton Cup is officially 15.41 miles or about 20 nautical miles sailing distance. Although Artemis finished nearly 2 minutes behind Luna Rossa in their 2nd defeat, they are improving each time on the water, and 2 minutes is still less than the closest the Italians came to Team New Zealand in the first set of AC races—that was 2 minutes 19 seconds! It's nice to hear that the crowd is giving them good support at least—so let's see what miracle they can come up with in the few final weeks of August, or is it really "too little too late"? The 'Americas Cup' final, with Oracle (USA) defending the Cup against the top Challenger, is due to start the 2nd week of September.
Well, the time ticks by and we are now only 3 months away from the start of the Louis Vuitton competition to select the final challenger and less than 6 months from the start of serious racing for the prestigious America's Cup itself! First of all, the 'arena' at San Francisco is getting prepared for the 100s of thousands of visitors anticipated to visit the city this summer. Not to be forgotten, at the end of August after the Louis Vuitton Cup is over and the AC challenger decided, 60 youth sailors aged 19–24 will compete in the Red Bull Youth America's Cup.
Well, Team Emirates New Zealand is still looking very impressive, but not resting on their laurels either. Check out this video (link below) and fast-forward the slider for two impressive minutes on Crew Fitness, starting at 9:20 on the scale.
As I've anticipated and written about from the start, one of the main items of development are the foils, with their potential ability to hydrofoil the boat clear of the water. The Italian Team is the other team with only one boat, but realizing early on that they would not get up-to-par without a sparring partner, they made a deal with New Zealand to share a good part of early design work and in fact, have almost identical hulls. Here is ample evidence that Team Emirates has been testing a variety of foil configurations and evaluating their relative performance on their SL33 test platforms. Recent video from New Zealand (see link below) is now showing that Team Emirates new boat is significantly faster than training partner Luna Rossa, as well as faster than its first AC72, now claiming 39k in just 17k of wind! Interestingly, the second boat for Team Emirates is now sporting a dagger board (with attached foil) that has a simple curve for the vertical part, compared to the more S‑shape used on the first boat.
This change has seemingly brought the foil design somewhat closer to the one being used by Oracle‑2. On May 12, 2011, the Italian Club Nautico di Roma withdrew as 'the Challenger of Record' and was replaced by the Royal Swedish Yacht Club, sailing Artemis. Oracle's hulls were built inside the team shed in San Francisco, along with other components such as the cross-beams—but interestingly, the wing sail was built in New Zealand (by Core Builders). Let's first review what these 'sailing periods' are all about and what they might mean to the four teams that will be competing. It has been said that 'originally, these boats were not primarily designed as foiling boats', but the experience in New Zealand is now clearly showing that if one does not tap the potential of foils and optimize their use, a competitor will soon fall far behind.
Rule 5.14 states that 'devices in, on or near any hull, rudder or daggerboard for purpose of altering waterflow of the boundary layer, are prohibited'. Regardless of this glance at the rules—all four boats are indeed now sailing with foils on their daggerboards and from what we've seen of the New Zealand boat to date, perhaps 'that part' of the daggerboard is currently throwing out a challenge to, just what IS 'the primary use' of the daggerboard on a AC72! One point of interest is the way the International Jury responded when asked to rule last year on the way the dagger board was to be measured, as the NZ approach (also backed by the Italians) was being challenged by USA and Sweden. It's also interesting to note that in 2012, one of the cup entrants (undefined), requested that the Measurement Committee look at a couple of possible designs for articulating foils.
The US Measurement committee reportedly found no specific reason to ban the non-powered version. Personally, I have always liked the clever, progressive foil design of the 1st NZ boat (see my mention of this in past article on Foil Variations dated Nov 9th 2012) and now it is becoming clear that this team will be concentrating even more on their foil design than any fancy improvements of their wing sails .. Here's a pic of the boat hitting a wave at high speed—and there are 5 crew members in that thick spray—all hanging on to winch pedestals no doubt!
This proves that their boat is both strong AND fast—a tough assignment for any on-the-edge design. While on the subject of the Rules, it's worth mentioning that, unlike most racing classes, the AC72s have both a minimum weight (normal) AND a maximum weight! What this might mean is, that if a boat wants to add some fancy gear to improve efficiency (where not outlawed by the rules), then they might have to shave some weight off the hull structure and risk some potential failure should conditions get rough. In order to get a sense of just how well the Kiwi boat is running on its foils, take a look at this YouTube. The Kiwis may not have the money behind their challenge that the defending Oracle team could come up with, but one has to sure admire their systematic approach and teamwork so far. But it's not finished yet—there are still some 6 months to go, although at this point in the preparation, the New Zealand challenger is clearly setting the pace.
To get another sense of what it's like to sail on a AC72, you may enjoy this report from Sail-World. In one interview, it was interesting to hear Gary Jobson comment that these AC72 challengers are apparently only permitted 30 days of sailing prior to some deadline. As time ticks down, it now starts to look as though the Korean entry might be a 'no-show'—and should that be the case, there will be just three challengers (NZ, Italy and Sweden), not four. ORACLE (USA) — after only a couple of days sailing, she's now under repair and re-evaluation after her premature and rather disastrous capsize. EMIRATES (NZ) — now hauled out and being 'tweaked' after 16 days of impressive sailing. As predicted in an earlier post, we can now start to see (and guess) that the boats have initially gone with different main foils. Finally, New Zealand seem to have the most complex design, with a curved board AND an 'L' blade at the bottom.
So no two boats are exactly alike in the foil category but in all cases, the exact positioning and built-in attack angle is clearly VERY critical, as the rules do not permit it to be changed while underway. Something many sailors have long believed, is that the best skippers are those who start and initially sail a LOT in very small boats. What Tom Slingsby has done, is seriously race LASERS (to win a Gold Medal in London this year). Another interesting aspect of these boats, is that new technology is changing the rules and making them more finite than existed in the past.
But for these AC45s (and hopefully the AC72s also), they are equipped with a very precise satellite positioning system plus a unique system of lights, whereby the race committee boats can rapidly communicate with the boats racing. If a boat considers itself fouled, a red light is turned on to let all know they are protesting. It may take a long time before the weekend racer will see such sophistication for their local races but it's something that will most likely grow in use over time.
The LIVELINE software, plus added video cameras and mics, now combine to make this an incredible experience for the viewer and in my opinion, this will change public attitude towards all sailing for ever—regardless of what boat is sailed.
November 1, 2012: The Italian Team Luna Rossa has now launched its AC72 in Auckland, New Zealand.
Luna Rossa crew members along with skipper Max Sirena, have already been training on their AC45s and they've shown to be a potentially competitive team, winning two of the earlier World Series events—though falling back at the last event in San Francisco. Another exciting development is a new World Youth America's Cup event to be held in AC45s, with the very top young sailors in the world coming together at the beginning of September 2013, to race in San Francisco Bay, just before the full-blown AC72 America's Cup itself.
Officially called the 'Red Bull Youth America's Cup', this will open up new opportunities for talented young sailors to become involved in future America's Cup challenges.
October 22 2012: Team Luna Rossa (Italy) AC72 is now due to be launched this Friday (Oct 26).
Team Artemis (Sweden) just launched their AC72, but while doing some pre-tests under a fast tow, they heard some hull (connection?) noises that they want to check out, so have hauled the boat out for detailed inspection. In contrast to the AC45 that is effectively a one-design boat, the AC72 permits some variation between boats.
Although it is unclear to me if this would be permitted, it seems to me that some form of bow deflector could help prevent the nose dive that looks eminent with that long, straight keel. If you drive that long bow into solid water at close to 30k, it would appear to me to actually drive the bow down, rather than lift it up. The AC45 has a generally similar hull form, but in this case, they have a mobile crew weight representing over 23% of the total weight that they can bring aft—whereas on the AC72, this important mobile crew weight, only represents about 14% of the total weight.
But it would seem very unlikely that we've seen the end of such accidents—especially when the serious racing starts. Ever wondered if these developments with rigid wingsails might roll over to more accessible sailboats?
As fancy silver jugs were often presented to the winners in Victorian times, it would not seem unusual for the Trophy presented to the crew of the boat 'America' in 1851, to look like a large jug—with its added decoration adding prestige to it. About the same time in the US, we had the song about "The Little Brown Jug" and such an earthenware jug became the prestigious trophy for the American College Football rivalry between the U of Minnesota and U of Michigan. Even today, it is not at all uncommon to present an engraved pewter beer tankard as a trophy—so the connection between a 'drinking vessel' and a 'trophy' continues.
But further research on this, has confirmed my belief that this goes back even further, to the use of the original two-handled jugs for olive oil or wine called Amphorae. Well, records show that Greek Olympian winners were presented with an Amphora filled with wine or choice olive oil—so that's probably the first link with a cup or 'drinking vessel', being used as a trophy. QUES: As I can clearly hear Aussie voices amongst the crew of the US boat Oracle, can you tell me what makes an Italian entry for the 2013 America's Cup, different from say, a Swedish one? Personally however, I hope the AC45 World Series continues to bloom and that enough individuals from countries all around the globe will gain the experience they need to sail the larger boats.
However the rumours, secrets and lies flying around regarding Oracle - has to be disastrous for their campaign.
Location: Melbourne, Australia John Bertrand is onboard with the concept and believes that the multihull format could produce close racing even if not in the conventional sense. That upwind foiling sounds good-especially if they have figured out how to do it so its actually fast to the windward mark.
Sean Langman and Team Australia has announced he will be running an exhibition race with another ORMA 60 trimaran from New Zealand (Team Vodafone Sailing), starting 2 hours after the Sydney to Hobart Yacht Race on December 26, 2013.

On a brisk October afternoon on San Francisco Bay, Spithill is working with his team, practicing for the America’s Cup, the biggest prize in sailing.
A series of interconnected cockpits carved into the narrow hulls allows the crew to hunker down and grind two-man winches.
The team keeps track of top speeds, and with each new day on the water they inch that number up. In fact, in many ways, the race is perhaps best understood as a pissing contest between the world’s richest men. In the 19th century, a ship in private hands that could beat the best that the British had to offer was something extraordinary — an example of private money rivaling the power of a great nation. He wanted a return to a gentlemanly rule, but he also wanted to see the kind of balls-to-the-wall machine that he won with. So for the AC72, the designers started by estimating the maximum horsepower an athlete could exert over a 30-minute race and worked backward from there. In fact there are only three teams fighting for the right to challenge Oracle: Prada Luna Rossa, Artemis Racing, and Emirates Team New Zealand.
In higher winds, the AC72s can hydrofoil — quite literally fly — thanks to trick daggerboards that lift both hulls out of the water.
He realizes that if the worst were to happen, if the wing were to snap from the body of the boat, then the hulls would turn turtle — pinning all of them underwater and giving them only the pocket of air inside the overturned cockpits to breathe. From there, still a good 15 feet in the air, they jump into the cold bay, one by one, to be picked up by Ian Burns, the team’s design coordinator, who was following Spithill in one of four chase-boats. The plan is simple — just right the boat the way the crews righted the smaller AC45s: Attach a line between the high side of the craft and one of the chase boats, gun the throttle, pull the catamaran onto its side, then reorient and pull it upright. A barrel-chested tank of a man, Turner has been building boats professionally since leaving school to apprentice as a boatwright at 16, almost 40 years ago.
Pieces of the wing break off, to be chased down by the motorboats, but the great mass of it — several jagged pieces — is still connected to the hulls by hydraulic lines and control ropes. Just repairing the wing will cost well over $1 million (and perhaps as much as $2 million). It wasn’t just the lousy decision his young protege made in attempting a run in dangerous conditions. He argues that even though going out for a sail in such conditions was a rookie move, he could not have ordered Spithill to turn around, because overruling a skipper’s decision is tantamount to castration.
Paul Cayard, CEO and tactician of Artemis Racing, has plenty of experience with the tricky conditions in San Francisco Bay. The skipper then brought the cup back to the USA and presented it to the NY Yacht Club with instructions that other nations could compete for it in future one-on-one 'match racing' events, provided they met certain criteria. The new boat would be called an AC72 and there would also be a World Series, using a closely related AC45 model for prospective challengers to train crews on—as both boats would sport a hi-tech wing sail. The team that will DEFEND the cup in 2013, is the ORACLE team from San Francisco and they already have their two boats sailing. Already, the first of the ORACLE boats has capsized while practicing and in fact, was swept 5 miles out to sea before they could control the situation, cut the mast free and slowly tow her home, and the wingsail was reportedly trashed by the rough conditions. There were also teams expected from China and the UK but, for 2013, they've decided to stay with the AC45s and race in that World Series to gain more experience.
That challenger then races an extensive one-on-one match series against one of the ORACLE boats for the cup, presently scheduled for early September, 2013. In order to achieve that, they have hired a promotion specialist, who was also a professional sailor.
This helicopter-shot shows a NZ hull just hovering over the stern of Oracle—and these boats were flying at nearly 40k!! For a tiny island nation and far less money available, New Zealand did a fabulous job and without them, this would not been the incredible event it ultimately was. For the 5th and 6th races on Tuesday (Sept 10th), NZ should start on starboard tack for the first race of that day while Oracle (USA) will have it for the 2nd. Here are 3 interesting sites to get info, as by the time I write another report, this will likely be all over. The winner chooses the next venue, the boats to be used, the format to race under, and the date"—that's BIG!! This will be a best of 11 races (6 wins) and should be all settled by the end of the month, if not before. Then the true FINAL for the Americas Cup itself (in AC72s) will start—when USA's Oracle crew will attempt to defend its prestigious title against the winner of the Louis Vuitton Cup for challengers. It's good to keep in mind that due to their tragic accident, they only got this boat on the water July 24th for the first time, whereas the two other challengers have been sailing for well over 2 months. This would mean that they need the stronger winds to be competitive—and time is running out.
With the racecourse stretching from Crissy Field along the city front to Pier 27, there will be many vantage points for fans and spectators to catch a glimpse of the action. Ten teams from eight nations will compete in their AC45s, over 4 intense days of competition.
I think you will enjoy to see how they are offsetting their relative lack of funding (compared to the USA defenders), by working on many individual parts of the whole effort and crew fitness is certainly one.
When the Swedish boat Artemis finally got to sail against the rebuilt Oracle AC72 recently in San Francisco Bay, they learnt a brutal reality, that their boat would not be competitive unless their foils were modified and enlarged to lift them clear—so it's 'back to the shed for mods' for Artemis, as they only have one boat to play with. Luna Rossa has since sailed a fair amount against the hot New Zealand entry and will come to San Francisco, better knowing what it is up against. As it's just too time consuming and expensive for them to ever sail their own AC72s against each other, they are working with two smaller cats, the SL33s—particularly for foil development. While Team USA has two AC45s to train on, it appears that the smaller SC33s may have provided a more flexible base for foil experimenta­tion.
Note the difference in the port and starboard daggerboards—one curved and one straight.
Powered by its tall wing sail and with the ability to hydrofoil, the AC72 can travel at more than double the windspeed. It could be that this is not only easier to raise and lower, but might be showing higher net lift than the first design.
But according to ACRM Regatta Director Iain Murray, as of last August they had not begun construction, although the team claim to have a design and the materials to build it. Where do things stand as we close in on the end of the first sailing period for the AC 72s?
In an attempt to keep costs down, the US committee decided to limit the number of sailing days within certain calendar months for all the teams. This has led to NZ having an upper hand in knowing what their boat can do and this knowledge has been immediately rolled into many small design changes for their second boat that they will start to sail in February. The Official Rules do not help much here though, as there might even be a case to be made, that foils are not even permitted! Of course, the boundary layer is the layer very close to the foil surface—but is that not what provides the lift in this case?
This would imply a very legal reading of the rules—following 'what is said' rather than 'what might be intended'. With data from stress gauges etc, this is a great piece of information for them to finish their first 30‑day period with, and something the other teams cannot match at this point in the game.
Well, from the little one can find out to date, the Kiwis are definitely sacrificing traditional rounded boat hull shape in order to get up on those foils as soon as possible. Here we get a view from an adjacent motorboat at full speed, and one cannot help but marvel at what has been achieved in such a short time period.
Check this next video to see how the crew are preparing themselves for that potentially dangerous fall from one high hull to the water, should their boat ever end up as Oracle did.
Views given are totally those of the writer and may disagree with official releases or other published data. The Swedish ARTEMIS passed a 2-week inspection after tow-tests produced a few strange noises—and they'll soon be sailing. With some 'tweaks' and added fairings, we can expect this already fast boat to become a little faster.
USA and Italy, both seem to have straight foils but with a sharp 90 deg bend at the bottom to work as a hydrofoil for lift. This means that when the board is down, the 90 degree tip foil is no longer horizontal—but more like a vee. But all of a sudden, as a noted 'super wind reader', he now finds he's a tactician on one of the ORACLE boats! Racing sailors will know very well that basic 'right-of-way' rules change when a boat is within 3 boat-lengths of a racing mark.
The lights can be seen in 3 locations; the rear mounted 'Christmas Tree', another on the bowsprit tip, plus a couple on the main cross beam. The committee then makes a quick decision and the fouling boat is quickly advised of an offense through a blue light remotely lit on their boat at all 3 locations. The chief team officer, Laurent Esquier, apparently said that: "carbon fibre, the primary construction material, is a strange animal.
For one thing, we will likely see some variations in the foils—especially after the spectacular capsize by ORACLE 1.
I was made to think back to the first experiments with the catamaran by the Prout brothers in the UK in the early 1950s, when they quickly learnt about pitch-poling.
That's an important difference to control trim in extreme conditions as any small boat sailor well knows.
Apparently each crew member is equipped with a 20-minute cartridge of oxygen within their clothing, 'just in case' they are trapped under a boat that has flipped! The bottom line though, is that all these teams have hired LOADS of experience and I'm sure they will look at all the options permitted within the rules. A few years later (~1872), we find the famous trophy created for the British Open Golf Championship that was actually a fancy jug for claret wine—being as the dark red wine was often drunk by 'the elite' in society. That implication of 'the ultimate goal' could make it a natural to be selected as a trophy.
These were as common in early times as a flat wood pallet is today, and were mostly used for transport and were so cheap, that they'd be broken up after what they contained was delivered and used. They even found one dated around 600 BCE that was engraved 'Prize from Athens' and some have figures of athletes painted on them that lends weight to this theory. If you read the governing Protocol issued by the Defenders who control such things, there is clearly no requirement for ANY member of the crew to be from the country that entered the team for the competition.
This freedom was primarily defined in the conditions ('Deed of Gift') spelled out in 1887 and has been there ever since. It was realized that 'this old cup' would not last unless sponsors were found, as costs are sky-rocketing and sponsors want the public to watch this event.

Then, perhaps, the new winner will redefine the rules so that each team entry will have a closer tie to the country it represents. I would love to see these things go around again in NZ so I can whip over and have a gander from over here in Oz. That's what this project is in terms of these multihulls and I like that; I think it's right and proper that the America's Cup is that. Naiad has been appointed to design and build four support vessels for the Defender's AC45 and AC72 yachts.
These complex hull forms allow Naiad to maintain high rates of speed while retaining a deep-V shape and minimizing drag for maximum fuel efficiency. In the past Naiad Design has also produced designs for support tenders for America's Cup competitors, dating back to the 1992 event in San Diego. Powered by twin Cummins QSB 5.9-litre, 480 HP marine diesels coupled to Mercury Racing's new NXT1 diesel stern-drives supplied by Cummins Northeast, these 50+ knot vessels are the core of ORACLE Racing's support fleet. A key driver is the signalled intention by the International Olympic Committee to select a basket of events that will be contested.
In the olden days we did not have television until I left school and they had a thing called print magazines, that reported events between two weeks and four months after they happened. She suddenly spluttered and laughed, took off her headphones and motioned for me to mute Diehard. This way, you can access your favorite links from any computer, revisit your favorite links later and keep an eye on specific sites, or even suggest reciprocal links which can be added. In 1950, more than 90 per cent of fish caught commercially were taken in the northern hemisphere, says Kurlansky.
Every other section of the draft summary was reduced to similarly bland statements or deleted altogether.
Then Team Oracle wrecked one in San Francisco Bay, showing just how fragile the big boat, and the event itself, really is. How this will affect the team and the overall America’s Cup competition remains to be seen.
It’s nearly identical to the course he has already run four or five times today — with two subtle differences. The boat pitchpoles into an ass-over-teakettle capsize: bows down, rudders up — putting Team Oracle on a heading straight for the bottom of the bay. The names are familiar from the history books and nightly news: Forbes, Vanderbilt, Morgan, Lipton, Sopwith, Turner, Koch.
If the AC72 were any larger, mere humans wouldn’t have the muscle to change the angle of the wing or to lift a secondary sail. The teams would barnstorm around the world, racing shrunken versions of the AC72 — called AC45s — to drum up interest in the main event. And crowds are sure to throng to the shore, watching for AC72 crashes, like they did for the AC45 in the World Series. No one is thrown overboard, but there is a tumble belowdecks as the 14 crewmates dive into the cockpits and fall on top of one another. So, still wet from his swim, Spithill grabs a towrope from the deck of the chase boat, jumps back onto his AC72, and hauls himself up the netting to get to the highest point: the stern. Thanks to the win on the wingsailed trimaran in 2010, Oracle entered the contest as the only team with real wingsail experience.
One of the AC72’s most outspoken critics is Scott MacLeod, managing director at WSM Communications, a sports-marketing business, who has represented corporate sponsors in every Cup going back to 1992. At least this first article will contain a collection of info that will 'set the stage' for a VERY exciting event. Fortunately, the final Cup races are not until early next September!Here's part of the story: Oracle sailors' account of capsize. The first boat to win NINE races will be awarded the cup, and then the next America's Cup challenge will be held in a location chosen by the winner. Stan Honey came up with 'LiveLine'—a form of accurate grid that can be superimposed over a TV image, in order to see exactly where each boat is in relation to its competitor. Starts will only be made if the wind is under 22k—but this is adjusted for the tidal currents at that time, so could in fact go higher by a couple of knots or so. Much of the racing will be viewable from the America's Cup Park (at Pier 27), which will be the center of attraction during the three months of the America's Cup season. If you continue on the video at 11:20, there's another interesting 2 minutes on 'video analysis'. The Italian team has probably gained a little insight into 'where they are' as they were able to train a little with the Emirates in New Zealand—but they are still many days behind. Whether the other boats will be able to successfully play 'catch-up' as far as foil development and efficiency, remains to be seen but I see this as a huge challenge for them. This means pushing the buoyancy down as low as possible in the hulls, to the point of making them virtually flat-bottomed and box-shaped—particularly at the bow where the initial lift will come from.
While information has been reasonably researched and believed to be correct, there can be no guarantee of absolute accuracy.
The Italian boat has only just started sailing, but it will be interesting to observe how she does in her planned training runs against the improved New Zealand boat.
It's not totally clear, but it appears that the Italians have that lower hydrofoil surface slightly pointing aft, whereas Oracle appears to run it more straight athwartships. This should somewhat cushion its effect in waves and make the foil more effective over its full immersed length. But it was left to the boat being fouled to prove that distance—a very difficult thing to be accurate about, especially so when speeds are high. This confirms they have been penalized and the agreed penalty is typically to ease off and fall back 2 boat-lengths behind their adversary.
It blinks faster the closer you get, going solid when you're over—instigating another penalty. The Italians are expected to be serious competitors for the Louis Vuitton Cup, this being their 4th AC challenge. These youths can either be already affiliated with the current AC45 World Series, or they can apply to qualify through a long and tough Selection Series.
It appears that, while the foils may permit hydro-foiling, the rules apparently do not allow dynamic control of these foils on the water, and this may have contributed to the capsize.
In this case, they solved the issue with short, angled deflectors on the bow—generally on both sides of each hull. If they don't accept some forward hydroplanes, then a little more buoyancy up forward, especially at the deck area, might have saved the ORACLE flip—at the expense of a tad less top speed.
For the ORACLE crew, they must be feeling very fortunate that this gizmo was not needed and that, despite the height that some of the crew found themselves and the deceleration involved, no one was hurt during their fall. I cannot help but wonder what variations the Korean team will finally appear with, being as they are now the only team left who have yet to 'play their hand'. The only thing I've found is that, 'the hulls are to be laminated in the country that enters the boat' and that a recognized yacht club from that country, registers the challenge.
Being as there is generally only one team named from each country represented, this also means that the winning country gets a say also.
So the new rules are aimed at giving each team a fair chance to keep the racing as close as possible. While info has been reasonably researched and believed to be correct, there can be no guarantee of absolute accuracy. Integrated crew communications systems and shock mitigating seating systems are being considered.
Among the spoils for the winning team is the prerogative to rewrite the rules of the competition, including determining the shape and construction of the boats that will be used in the next go-round.
Topping it all off is a rigid wing — 13 stories tall — that does double duty as both the boat’s engine and a billboard for the massive egos that animate the race. The stories are the stuff of yachting lore, told by the light of a campfire in the Bohemian Grove or swapped over Manhattans at the Knickerbocker Club on Fifth Avenue. The AC72 is not just an extreme sailing machine; it is the most extreme machine of its type possible. Last year in the gusty, choppy conditions typical of a San Francisco summer, three AC45s went daggerboards up over a four-day practice period.
Its performance has proven even more awesome than advertised, but the boats have turned out to be simply too expensive for many racing teams. After he arrives, he hears the sharp snap of the wing shearing at the foot of the mast, causing the rest of the boat to fall on top of itself, upside down. To entice the other teams to come out and play, Oracle agreed to limit practice time on the AC72 to a mere 30 days before January 31, 2013. Yet the possibility of someone pushing the boat too hard and capsizing was never addressed in the planning phases. Most of the corporate money that used to be in the event has fled: The AC72 is just too expensive. The choice of a large, hi-tech, multihull for this prestigious event should certainly inspire a lot of sailors to take another look at this rather different form of sailing ;-). The winner is also deeded the right to re-write the rules for any new challenge, should they so desire. As each boat will be feeding military GPS data to the system, they claim accuracy will be within 20 mm! This is partly due to the initial work done by Luna Rossa when sparring against the Emirates boat in NZ, and partly due to the Swedish team having to rush to get a 2nd boat in operation, after their first one capsized, broke apart and caused the tragic loss of one of their key crew members, 'Bart' Simpson—drowned from being trapped beneath the wreckage.
They've pushed these boats very hard and reached top speeds of 32 knots, which is pretty remarkable for a 33 footer. So raising and lowering the daggerboard with a foil on it are apparently, not being outlawed on that basis—even though foils were never mentioned in the rules. They might also have added a little more volume to the bow with very slight increase in freeboard—just from glancing at the profiles.
His opinions are purely personal ones covering his assessment of the situation based on data currently publicly available. But then, the more they sail, the higher the risk of damage that could end all their efforts, so it's a gamble after May 1st. The Swedish Artemis appears to have foregone the horizontal foil but has a foil curved over all its length.
When their GPS indicates that this gap has been reached, the blue light goes out and a green light indicates they can get back up to racing speed again.
Within 3 boat-lengths of the line (42 m for an AC45), the boat there has right-of-way over someone else coming in—even if they are on starboard tack! The latter becomes important if they win, as that club is then responsible for the racing and location of the next America's Cup—sometime in the next 5 years. So the DEFENDER (USA in this case) has the upper hand and it's one reason that 'The Cup' has stayed in the US for most of its history!
Also, by choosing a 72-foot hi‑tech catamaran, the speeds achieved will likely be far higher than ever seen before for such a public sailing event and there will clearly be the risk of 'thrills and spills' that also tend to attract the general public. We merely seek to use it as a way to demonstrate that when there is a lot of brouhaha going on, the smoke screen ultimately ends up as a lovely, colourful flag as to the real intent behind it. The whales will soon be gathering again off the coast of Queensland to observe all manner of racing and cruising craft as they head North for a Winter in the sun.
This is why today Spithill is sailing a $10 million AC72 — a radical new yacht for a radically reimagined yacht race. Each team builds a slightly different variation of the AC72, but the general size and shape were devised by Ellison’s people at Team Oracle. The origin myth involves Queen Victoria watching a winner-take-all race around the Isle of Wight between a Yankee schooner named the America and 14 of the best boats in Britain — including the cream of the elite Royal Yacht Squadron. Once the line is attached, he crouches down in a cockpit and braces for impact as the speedboat hits the throttle.
By 1 am, with currents finally in their favor, they are able to drag the craft back to Oracle headquarters at Pier 80 on San Francisco’s industrial waterfront — upside down, broken, and almost completely submerged. It will take nearly four months of 80-hour weeks by a team of 24 staff boatbuilders (plus every odd rigger, sailmaker, and machinist that Turner can manage to shanghai) to fix the damage. He founded the World Match Racing Tour, a yacht-racing tournament that was the de facto training ground for the America’s Cup before Ellison decided to abandon traditional monohulls. There will also be a 'Digital Boathouse' where the media and visitors to San Francisco can go, see, and discuss this in real time.
If you'd like to learn more about what's involved in putting on such a complex event as this, reading the article published in a previous issue of the Wall Street Journal will help. If any of the teams have a 2nd boat, this can be launched from February 1st onwards and I understand that the sailing days*, can be shared between either of their boats. Then Rule 1.4(e) actually states that daggerboard means a retractable appendage primarily used to affect leeway.
Looks like a loophole to me and who knows, we may see some legal challenge on this subject further down the road. Of course, if the wind for the races that count were to be extremely low, then this form, which has relatively high surface area and friction, just might raise the speed at which they can start to foil and they might then lose out to more rounded hulls with lower basic friction. Gary further commented that boat speeds (in certain conditions) were already reaching TWICE wind speed.
It might not create as much ultimate lift as the 'L' foil, but it would seem to be at less risk to create negative effects at some trim angles. If they are over early at the start line, there's typically a 3 boat-length penalty indicated in much the same manner, a penalty that increases the longer a boat delays taking it. But application entries closed Oct 31 and the first Selection Series trials will be in February 2013 (in San Francisco), with the aim to have the very finest all trained-up for an exciting final series in September with nearly 20 countries involved in the initial races. On a shorter boat, I can see that this might permit a pitching bow to lift out of a wave with minimum of resistance. Twenty-eight-knot gusts push in through the Gate while water drains out of the bay at 5 to 6 knots. The sails have to be depowered, the daggerboards (retractable keels that drop from the center of each of the catamaran’s twin hulls) have to be adjusted, and the helmsman has to carve the tiller — all in split-second coordination. When a lookout spied the America coming toward the finish line in first place, the Queen asked who was in second. The men who financed and sometimes even helmed these boats saw themselves as puffed-up proxies for their countries.
While Oracle is in the shed fixing its AC72, the other teams will be out sailing, perfecting their systems and closing the experience gap. Further, there will even be an App available through iTunes®, for your Smart Phone or iPad® that will give you related information! The other 3 challengers will certainly hope they do, as this would give them far more racing time than they'll get if there remains just the 3 of them.
However, with that powerful wing sail, I don't personally see that as being much of a risk, and getting that long hull up off the water as soon as possible will allow their high efficiency foils to do their job. This initiative should pay big dividends down the road, re public interest in the event and the corresponding flow of capital from new sponsors.
But these boats will not be racing in open ocean conditions, so the longer boat will pitch much less and in the video of the capsize, it looked like the long, straight bows were driven under as much by their own form, as from the wind on their tall rig. Taken together, the forces acting on the boat are the equivalent of 33-knot gusts: gale-force conditions.
Ellison topped him (in every sense), building a carbon-fiber trimaran with a hard wing 223 feet high — so tall it couldn’t fit under the Golden Gate Bridge. There’s another climb and another towline secured, again to the high side of the boat. The new wing — which needs to be built in a factory in New Zealand — is a job three times as big. Right now, each of the challengers has to beat just 2 opponents to get a shot at Oracle for the big prize. At about 40 miles per hour, one of the hulls catches an edge, twisting the frame of the boat into a nosedive. The contest was like nothing the sailing world had ever seen — a real-life Godzilla versus Mechagodzilla. The real loss: 40,000 person-hours, or the equivalent of 20 person-years of full-time labor.
The boat — with Spithill on board and dragging the speedboat like a loose anchor — gets swept out under the Golden Gate Bridge and into the truly rough water of the open Pacific.
