An Olympic Gold medalist sailor died when the Swedish challenger to the America's Cup capsized. I haven't been following it closely, but this Wired article from 2011 covered many of the challenges and risks with these boat designs that were evident even then. Isn't it a kind of sport where boats do and will capsize, and you got to survive it capsizing?

Well NASCAR changed rules, used restrictor plates which limit speed, in the interest of safety?After Earnhardt died, they made other changes as well.I don't think any sport can afford the perception that they're taking shortcuts on safety in the interest of winning.

To the extent they make changes it'll be because they don't want their boats to flip over, not because they're worried about public perception. I assume that the guys working the cranks are selected pretty much for brute upper body strength, aerobic capacity and the willingness to keep their head down and crank in the proper direction when shouted at. I don't think it was the crash that caused the death, it was being trapped underwater for 10 minutes. Way it's described, it sounds like a lot of the crew's function is to act as counterweight when the boats are turning and it's tipped over on one of the foils. Location: Cocoa Beach, Florida Hydros More from Team Hydros including the first public picture of any C Class boat foiling! Next time you fly anywhere, look at the wing at landing, in full landing configuration, slats are extended for the very same reason. I don't have the numbers handy to prove that this has a clear benefit for a C-Class wing but it is very likely! Billy Besson and Jeremie Lagarrigue, competing for Team Hydros, gained a resounding victory at the Formula 18 World Championship, in front of no less than 184 opponents representing the Formula 18 world elite. The technological adventure of l'Hydroptere and its record-breaking exploits have been made possible by the support pledged since 2005 by Thierry Lombard, Managing Partner of the firm of private bankers Lombard Odier & Cie, whose foundation year - 1796 - is displayed on the craft's mainsail. Originally Posted by DCockey I believe the C class rules allow the use of lifting surfaces on the rudders for pitch control. The AC boats rake the mainfoils to control the angle of incidence of the mainfoil and therefore vertical lift -not pitch.
However, it would be much safer on the 72's to have controllable rudder foils that work with simultaneous control of the main foils.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
1) The black thing is called the Pod and it is interesting that it actually touches the water when sailed flat and in displacement mode. 2) Before 17 flipped there were several photos of the seal between the wing and the platform. 3) We have known for years that the foils attitude would be controlled by mechanical means around the bottom bearing. I was saying that the main foils would be pivoted about the lower bearing from the begining-but on forums like SA they can't conceive of that! 1) The Black Thing- this is an effort to extend the rig down to as close to the water as possible. Now I know Moths sail with a pronounced windward heel, but what is happening in this picture?
Location: Cocoa Beach, Florida 34th AC This is a great animation of how TNZ's foils used to work. This from a poster on SA: I watched that session in person and OR was clearly lower and faster then AR.
PS- Also was told that they expect to fly downwind only Doug, I think we agreed on this being the apparent choice of OR quite a while back (more than a few months), not just weeks ago. Originally Posted by P Flados Doug, I think we agreed on this being the apparent choice of OR quite a while back (more than a few months), not just weeks ago. I first postulated this some weeks before my post here and on SA(September 2012)-and before my friend corroborated it. Given what little we know about the details, it sure would be nice if sooner of later the big fast multis (OR 72 and Hydroptere) would open up a little more and talk about how well manual altitude control worked for them.

I'd like to know what was going through everyone's head that though this was a good idea to make. Gino Morrelli believes the next generation of America’s Cup catamarans will revolutionize upwind tactics. Early in the development of the original design rule for the AC72s, there were no restrictions on foiling surfaces. Photo by Daniel Forster You might recall, ETNZ took that serious nose dive in an early race, and Oracle did this less-radical face plant on the reach to the first mark in the deciding, final race, which could have come out rather differently.


With hulls now functioning as components of a foil-delivery system, the extra bow volume builds a safety margin with no meaningful downside.
For an easy point of cost saving, “That crazy aerodynamic structure on the underside of Oracle, fairing-in the dolphin striker, will be restricted. The big picture view of the 2013 America’s Cup is that Oracle Racing built a faster boat—more aerodynamic, twistier, harder to sail—and learned how to sail it just in time. Someone asked why Artemis Racing still has its base in Alameda, and their 45 is sometimes seen on the bay. Pardon my ignorance but demanding design criteria to make custom designed speed yachts not capsize is sort of like demanding surfboard design decisions so that you don't fall off surfboards, or ski design so that you don't break your neck.
Pardon my ignorance but demanding design criteria to make custom designed speed yachts not capsize is sort of like demanding surfboard design decisions so that you don't fall off surfboards, or ski design so that you don't break your neck.Multi-hull boats (Catamarans and Trimarans) do not really capsize in a traditional sense, ie. It's not a spectator sport, they're funded by rich sponsors and participants, not by the public. Rich people have been doing this for 150 years, I don't think they care about ticket sales. 60928.htmlIn the US at least, the events should get coverage since NFL season won't have started. We like to watch contests between even just a single pair of competitors--boxing matches, tennis finals, other tournaments where there's really only a handful of true contenders. I don't really know, but it doesn't seem like they need to see what is going on much and should really be in a crash proof capsule of some kind. Certainly if I was to design another C-Class (I was involved with Invictus for the 2010 campaign) I would look very closely at slats as one of the key area of development on the wing side. And if you want to brush up on the theory behind all this, look at Abbott & Von Doenhoff.
Unfortunately the boat rounded up in stronger winds and was damaged - but there was a direction that is still worth exploring. This is a good omen, about 2 months away from the season's main objective: The Little America's Cup, International C-Class Catamaran Championship, which will take place in Falmouth (UK) next September.
Bastiaan Tentij and Mischa Heemskerk, also competing for Team Hydros, and who will also be representing Switzerland in Falmouth in September for the Little America's Cup, finished rank 22 after sailing in the leading group for the main part of the race.
Notice the fences on the rudders and the weird kink in the lee board just under the lee hull. This is much simpler and more effective than controlling pitch by raking the main boards as the AC72's are forced to do by their rules. The rudder foil is a trailing foil and automatically controls pitch as on the Rave and Osprey. When racing the Wing will be dropped down so that there is a complete seal down to the bottom of the Black Thing. They don't use the windward mainfoil for lift-the rules stipulate that it must be retracted and only the lee main foil used.
The stb foil is different since the daggerboard is not curved but the foil itself is angled up. Once up on foils OR could sail lower and one noticable thing was the leeway it had, like it was 'cat-walking' sideways. AR wing profile looked better and they appeared to be faster straight line, tacking and getting up to speed.
He foresees the boats foiling through tacks without slowing down, and if there is no price for tacking, that’s a new calculus, isn’t it?
You would do this at the top of the wing, so that instead of pushing the boat over, it’s actually pulling the boat up. Restrictions were added at the insistence of the then-Challenger of Record, but we know now that the result was merely to make the boats trickier to design and less safe for the sailors.
A little more carbon, a little more weight, a little more windage, but equalized through the fleet. The whole team at Morrelli & Melvin Design and Engineering has been known to shove work and hit the beach when the surf is up.
They don't operate in a particular jurisdiction, so they aren't inherently bound by the laws of one. If someone got trapped under boat, then regulate the life jackets and helmets and the like so that people would not get trapped under boats so much. If you can sell the story well enough, you can get an audience into it.I think sailing is still too elitist and unrelatable to become really popular, but a lot of media attention can get people interested in nearly anything.
I don't know about the rest of them, but when they are cruising in a straight-ish line, shouldn't they be in some kind of protection? From the pictures that have been released, it seems FYH has both slats out (port and starboard) at the same time. A couple of times the leeward hull would be foiling and the windward hull was still in the water, this was very slow and the boat appeared to want to round up. His firm of Morrelli & Melvin wrote the design rule for what we will call, for now, the AC62.


Theoretically, if you’re bearing away around the weather mark in 30 knots, you can crank the wing inside out to get positive righting moment. We’ll be able to actively change the angle of the rudder posts to adjust the angle of attack of the T-foils on the rudders—in 2013 we could make changes between races, not during a race—and the T-foils will be symmetrical, and bigger. Where Oracle had a safety advantage over the Emirates Team New Zealand boat was in its protective cockpits. I voiced my stubborn optimism that it will, simply because that’s what ought to happen. It's more like being the fastest gun in the west than it is like a traditional sport.The America's Cup is not just one of the oldest sporting events in existence, it is THE oldest.
There are only multiple entries for the pre-Cup selection, and I don't know that they care how many teams enter.
There are only multiple entries for the pre-Cup selection, and I don't know that they care how many teams enter.Well, again, going off the Wired article which is the one source I really have for this, Ellison's goal was to make the event into a more successful spectator sport, but having only four teams even enter has pretty much ruled out that goal. Normally if the Pod touches that water it would be classed as a trimaran and therefore would be ruled illegal under the current rules.
Hydraulic servo powered by the grinders and controlled by the crew seems to be the answer here.
That is, ten feet shorter than the AC72s of 2013 and shrunk appropriately in other dimensions as well. After the fact we sat down with the Oracle Racing guys to analyze the video of that incident, and we determined that, if Oracle had done the same thing, they would have been upside down. When ETNZ stuffed it, bodies were flung forward against each other—there weren’t enough grab points—and as the boat sailed on, there were fewer crew on deck. I did some preliminary design work on such a thing for a senior design project in university (mechanical engineering). Fortunately the boat is measured without the wing, therefore the Pod does not touch the water (less displacement)and is therefore a catamaran. Add-in some one-design components, factor-in the fact that a lot of the design possibilities have already been explored—we know what the next generation will look like—and you have a boat that is cheaper to design and cheaper to build, even with amped-up technology.
You’ll have more chance to use low angles of attack to give you the highest glide speed through the tack.
Asking the boys to pump oil to generate hydraulic pressure for trimming built in a delay that just didn’t cut it. M&M also developed the design rule for the AC72s, and they were the principal authors of the design of Emirates Team New Zealand.
Instead, should the font tips hit a wave, it is more like hitting a wall of enormous viscous drag. The forces involved are quite large, as was calculated earlier, yet the dynamics are quite fast. Lucky they got their build weight and hull shape correct it must be really close at measurement!
But it’s one way to build a big rig that will perform in San Diego but survive San Francisco. The actuator needs to be both powerful, and extremely quick to handle the transient forces presented by the moving water. Actually if you look at the Cogito style element 2 design, you will probably find that upwind it has an ever so slightly smaller area (Steve maybe you can confirm that). This resulted in the windward hull come crashing back down into the water, that must have hurt a few arse's. They’re also part of cutting edge multihull racing at every level from A-cats up, and cruising cats from the Hobie Wave to Gunboats.
The Catamaran simply somersaults near instantaneously upon hitting a wave.Catamarans somersaulting are simply an inherent negative feature of Catamarans. And when I want to impress the nieces and nephews, I just tell’em, yep, I know the folks who designed the Jungle Cruise boats for Disneyland.
Larry wrote the check for the whole show the last time, but I don’t know how interested he might be in helping those start-up teams get a foothold. Yes, it is dangerous, but so is skiing or ice skating or any other comparable sport really, and you can't improve anything by regulating the skating blades. You can regulate the floating jackets, beacons, helmets, etc etc etc so that people would not get trapped under boats.
But you don't just regulate the ice on a skating rig (demanding a rubbery soft ice or something) so that one can't possibly fall on their head and die.
