World's Most Advanced Hydrofoil Boats Fly Above Water 

Also slows innovation. Should be two leagues. This and No Limit - see where it goes.

@@Bigbillyrayfan "Unlimited Class" already exists. It's called America's Cup. The goal here feels very similar to Formula E, which is to create a racing series that can actually survive long term and have close, exciting racing without it being a "who's got the biggest wallet" contest.

Same as formula E

A conversion kit is also available for VW bugs from J.C. Whtney, too.

which is why you can't really compare it to Formula 1, it's more like Indycar

The current record is 94.8km/h, set by the UK team.

@@Yvaelle 99.9km/h this last weekend in Saint-Tropez. Incredible.

@@Yvaelle how does that convert to mph

@@lastsinner1738 highway speed

99.9 km/hr = 52.07 mph

The fin itself projects the boat up u can buy a hydrofoil surfboard with no motor and it’ll “fly” above water

Hydrofoils are even common on kitesurfing

Shoot us a link

@@ticklefritz5406 do a RU-vid search for international moth. Also check out iqfoil, formula kite and wing foiling.

You said it Simon! Those Moths are stealing the show nowadays (and other foilers as the UFO, Skeeter and FlyingMantis as well). Great fun to watch and sailing has changed forever indeed! What a fun these boats are!

Is there another class of racing, a class where the hull stays in the water?

@@rickc2078 plenty of amateur and professional 'displacement' series are available

I was on a J-24 hitting terminal velocity at 18 knots under spinnaker and the crazy humming, shaking and vibrating it emitted sounds just like these F50’s as they scream past! I thought 18 knots was intense but these guys are a different breed!

Bro

f3k is worth a view then

How do you get in to racing quadcopters? I am interested...thanks!

@@EuroVrod I have been flying model airplanes all my life. I am very interested in technology in general. When flight controllers came around I wanted to know how they work and build a so called 'simple copter'. See youtube for that. But when a fellow clubmember introduced me to a fpv goggle I was completely hooked. Besides that I have also sailed all my life. Learned it when I was very young

This technology existed in serial boats in Russia for 60 years or so. Look for Meteor and Raketa.

There's also an argument to be made that the design would evolve faster if each team built their own boat within specs. Like in Formula 1.

@@Republic3D That would definitely be better. These teams can afford it.

I was flying a Wasp Falcon 4 in 1980 :) It bears little resemblance to modern wings but what fun :)

​@Republic3D F1 sucks because the richest teams win. Williams is never beating Mercedes. Cool that redbull has come on lately, but it's not interesting because the overall competition isnt there.

Why were you never curious enough to look for all these other great video's on foiling cats? There are several video's explaining exactly this, even some years ago. Just type "foiling" in the search thing, and watch them all. Please DO that, you had no idea those foiling kite surfers are just as interesting as those expensive cats.

@@voornaam3191 I have never had anyone complain about what I watch. kind of interesting. You give me the impression that you think you are better than anyone else. You're not. the thing is that I have only watched a few videos on foiling but I found that this video peaked my interest so I commented. I have a wide variety of interests and do not focus on one thing. You are obviously much more knowledgeable than I am on foils and I applaud you for that. Please do not look down on those who do not know as much as you do. I found the video to be very interesting to me from the perspective of someone just now learning about foils and foiling. I do not appreciate being stepped on for wanting to learn more yet have not reached the level of expertise that you obviously flaunt. don't bother replying to this reply to your comment. you will do more harm to yourself than me. Peace...Out! :o)

Wow maybe I'm wrong. I was kind of underwhelmed by the video. It just seemed like for every component of the catamaran she would barely explain it then say "THAT's where the speed comes from". She'd be like "These foils keep them above the water and THAT's where the speed comes from.... These sails catch the wind and THAT's where all that speed comes from... These raised buttons here are pushed by feel and THAT's where those speeds come from!" I'd be more curious to know how all those things make the boat go up to 60mph in a 15mph wind.

My father raced sailboats for quite along time. His boat was the Willy Willy out of Des Moines WA. It's only exciting when you have wind. Otherwise its hours of bobbing around the bay. Have fun and be well.

That would be cheating.

one time, in band camp....

Sounds like a self driving car. Lot of accidents in those, driving is not a simple task. And these boats don’t seem practical on open water, so this is more like a race car on a track than a practical vehicle

@@alw6589 There are some nice advantages of something like this. They basically produce almost no wake so they would not have speed restrictions on certain lakes and rivers. Sailboats also usually have far less restrictions and regulations on them, especially if they have no motor. Also buying marina gas is EXPENSIVE and handling gas canisters is a pain in the butt. Just think of a private craft version. Obviously you need it to be controlled by one person. I know they had little sailboat hydrofoils back in the 80s I think, but that company only made a few hundred and folded. It used floats to control the hydrofoils, but that would be FAR less efficient. It did have dual wing sails. It was only a single seater though, but it was fast and looked fun. Last I saw they never get thrown out, but instead they sell on eBay for a decent price and get rebuilt. There is like a fan club for them. A little Arduino or Raspberry Pi could likely handle all the calculations and the sensors should be fairly cheap. You would need servos or motors on the hydrofoils, the rudder, rotate the sail. I like the flying wing type sails too. A good display though is key with what would likely look king of egg shaped showing likely speeds from what angles. You would need wind direction and speed as well as motion sensors and a lidar to detect distance off the water and wave height in front. With a computer controlling the sale position and hydrofoils it would be impossible to flip one. Think if they had something like a 2 seater and a larger 6 seater to start out Maybe have a longer range lidar for detecting boats and the shore and maybe even a depth finder. Having GPS trip planning with tacking as needed would be nice too. Just saying... I would like to see a retail version of something like this again... and if it was handled by a larger company like Tesla he likely could sell enough to mass produce them and keep the prices low. Put a couple of solar panels on it to power the motors and a battery and you are good to go. Heck if there is enough power you could have a folding troller motor on the rudder that could back you out from a dock and maybe move you away from the shore into better wind if needed (very slowly). Heck you could likely pull a water-skier or tube no problems if you have decent wind.

@@toddabbott781 people already crash boats far too often and they’re currently the easiest thing to drive ever. that would be a torpedo on autopilot and would decapitate children until it was banned

That would be amazing

I got a feeling you occupied my house while I m on a year long trip in Singapore. Dont touch the cured meat in the basement OK.?

@@cemasti4524 lol... wasn't me. I've got my own charcuterie curing in the basement.

@@sparkeyjones6261 Just in case. I use that meat as mice+rat poison. U know there is poison inside Oh well that is to get rid of squatters too.

Record is 60mph/ or 100km/h, by the French, and a boat concept called Hydroptere.

It's simply not practical or economical

Yes, it's amazing but I miss the days of tactical sailboat racing. Now it's just an engineering race. They don't even engage with each other for the most part.

The person in Team USA is basically another pair of eyes for the skipper but I can imagine a team when the actual skipper is the strategist who gives commands to the helmsman.

Simply by maintaining the speed necessary to keep the boat up on the foil (easy when you say it like that, lol). It took a lot of practice and a fair few crashes but looking at footage it seems the crews figured it out preparing for the America's cup in 2017.

They follow different lines than a floating monohull does. Catamarans have always rounded a racing buoy far wider, it pays to keep a high speed and do a small detour. These foiling cats do the same thing. Just faster...

flight controller drives while swapping sides sometimes (someone in the afterguard)

They call it aerodynamics and if you use your own eyes and brains, you see that those sails are evolving towards solid wings. A catamaran mast started like a round pole, which has far less drag than you'd expect, just check a windsurfers mast. Then the mast turned into quite a large wing, with a sail attached. And today mast and sail design can be done using a computer, finding what is strong, light and most effective. Just like the foils themselves, fast computers led to amazing innovations. Today you cannot build a winner ship anymore, just applying your common sense. No matter if you are an expert already, you do need to test your ideas on a computer, or your boat will not win races. You can search for video's on sails and masts, I bet there are good ones explaining how things work. The rough idea is, the sails have an effect on the wind, the wind direction and speed is changing a bit, compared to what it was before the boat passed. There is an energy exchange. And then things like the shape of the mast and sails have an impact on how the air moves around the sail. There are theories about that. And practical implications: how do you adapt your sails to the wind speed you have, how do you trim a sail. And these foiling cats and surfers are so fast, you got that funny problem, that the wind starts becoming a head wind, no matter what direction you are going. This effect means, there is a speed limit. For sails that work better in this self induced head wind, will result in a higher speed. Sails that do not push upwind so hard, well, those sails will be slower at any course, because a foiling cat will accellerate until the wind is a strong head wind at any course. These cats have a certain factor, some can sail four times the wind speed. For slower designs, those could do "only" twice the wind speed. Which can still be horribly fast, by the way. You got the idea, it has to do with the drag of the foils, and the quality of the sails, those must perform excellent in upwind conditions, for that is what a foiling boat is doing in the end. Hope you got an introduction. Specialists can tell things more specific, this was just what I picked up from RU-vid, and I guess this is what makes foiling cats so special. Remember, those high speeds are pretty dangerous, steering a fast foiling cat is an intense experience, you need to learn new skills, or you will end floating upside down, break the mast or similar oops. There are sailing schools that include foiling cat courses. When you live near water, you could take time and learn sailing a small foiling cat yourself. Maybe that's an option?

@@voornaam3191 👍

I dont think this class uses the same system the Americas Cup boats use, these guys are actually winding winches pulling sails up trimming as well as manually winding the dagger board foils up and down. With the AC75 monohulls the grinders are keeping hydraulic fluid pressure up and the sail trimming is controlled hydraulically by a crew member with a hand held controller box like a PlayStation controller, the dagger boards are electrically powered using batteries which is the only stored energy they are permitted to use, the grinders control these with foot pedals.

Not really, a spinnaker only works downwind, while these things are so fast that per the apparent wind you're always going upwind and faster than the wind (and we're talking multiples of the speed of wind, which is crazy)

@@macsen5422 This

Hydrofoils allow boat speed to double or triple wind speed. Try that with a spinnaker.

Whoever has the best computer simulator wins the race. The talent is the mathematicians and coders that are writing the simulators, not the sailors. Traditional skill doesn't really give you an edge anymore, especially when the computer is telling you what line to take.

IKR!

They are attached to the boat because of such concers. Peter Burling fell off this week as he ran across the boat and he was held by his tether, too high to touch the water, so he was fine.

@@timotheyszczepanski6644 That’s good to hear. Otherwise there’d be no way to escape a blade coming at you.

What about marine mammals and fish sliced apart ?

@@jackiefitzpatrick2906 True. Especially since sea mammals need to come up for air. I hadn’t thought about that.

Thanks for that info

The monohull is crazy!

Can't wait for the 100's And 150's...

Arguably offshore racing classes like the imoca 60s or ultime trimarans are more advanced than either ac75s of f50s

(third most advanced)

right on comment...avid kiwi yachting fan here.

you've never heard of the america's cup?....it oughta be renamed the kiwi cup!

They all use money to transport the boats.

@@zedsclanwallace8558 but do they ship them? Do they take apart and trailer them, fly them or actually sail them? I am curious how they actually transport them.

Couldn't help myself ;)

@@clairereilly Claire I just want say you are awesome! I do hope you give us an inside look of the International Space Station someday! :)

And the kiwis invented another impressive water sport. Couldn't help myself either.

Normal vessels kill plenty of whales, they should ban all boats.

Is the same as other racing vehicles: you just use them in a racing track in competition. The same as you don't race a rally or an F1 in a public road open to the public.

@@Buran01we should ban all cars

@@royaldecreeforthechurchofm8409 I agree, not a big deal for me.

@@Buran01 ban all youtube replies

Unless there's no wind, then it's bobbing around the bay for hours. My dad raced.

More like Indy considering the boat model is fixed by the series.

Who wants to watch robots race, boring.

Nacra 17 is about the closets out now

Maybe.. but you are comparing a leisurely cruise to the apex of sailing, where technology and teamwork meet in unison and create something else that is awe enspiring and beautiful in its own right.

@@duncanb1981 It is very impressive, I can't deny that. However, beauty is very personal and I don't see beauty in those monstrous machines. I raced yachts for 20 years and participated at the world class level. My Brother is three time world champion in Thunderbirds. So I've experienced intense racing, and found those experiences to be fun and exhilarating ways to connect with Mother nature. Conversely, in these over the top high tech machines it seems that the helmets, goggles, electronics and foils separate the participants from nature making the experience technologically isolating rather than natural and intimate. Of course that's just my opinion. My favorite water activity is body surfing naked, it's just me and natural waves on a tropical island where I live a simple life. Less is more.

You could ask the same about football or baseball but in this case 10 teams with a £2 million pound boat vs well lets say each stadium's cost approximately £½-2 billion x92 or $½ billion x30 respectively... And then there's the engineering feats unlike the football... mind, we did get a pea-less whistle 😉, pefecting mass distribution (baseball) and a lightweight durable material (baseball bat) In a way you're not wrong, I think F1 and this are the biggest "profitless" sport's. Lol

​​​@@TheEvade84I totally agree. It would be less costly overall than baseball, F1 or NASCAR. Think about it, there's only really the cost of the boat, pay for the crews, and the transport. There's no stadium needed, no wasted fuel. Just some super advanced sailboats out on the water that probably cost in the same range as an F1 car, NASCAR, or WAY cheaper than a star player salary.

Why, do you know hew story? Maybe she's a prodigy, you don't know...

She sure got some connections

Yeah- I'm sure she was selected for this role because she's young and beautiful... but it could be that she's already proved herself in ways that've impressed this multi-million dollar operation. Time for you to go home.

@@peterwright4093 Proved herself in what way exactly? Tell me what she's done that would earn her a position on one of these boats, above everyone else out there with years of experience. You'd have to be a moron to think she's qualified or earned her way aboard this boat

Yeah its the billionaires fault. They should cancel sail GP so I can have healthcare

Your perception

And this is hurting you how????

@@steveb6244watch rollerball. Then maybe you will understand. Probably not though. The original with James Caan not the crappy remake

It’s a fine example of what can build if you work it out. Some people build value, and wealth follows value. Some people build talking points, which is only talk. It begs valuation without merit and gains only jealousy in its own dearth.
