SailGP is sailing redefined. Established in 2018 and headquartered in London and San Francisco, SailGP is an annual, global sports championship featuring bold, cutting-edge technology and awe-inspiring athleticism. The fan-centric, inshore racing takes place in some of the most iconic harbors around the globe and culminates with a $1 million winner-takes-all match race. Rival national teams from Australia, China, France, Great Britain, Japan and the United States battle it out in identical supercharged F50 catamarans, engineered for intense racing at electrifying speeds exceeding 50 knots (nearly 60 mph).

You guys should put louder music next time, I could barley hear it
Well that cleared up a whole lot of nothing.
Would one or two of you guys who understand the dynamics of wing-sails v. wind-sails, do a piece explaining all that stuff to us? As far as I understand, the wing is a real revolution in sailing, as it operates on the principles of an airplane wing, pulled by pressure differentials; and a conventional historic sail is more like a hot-air balloon, by comparison, pushed by the wind. For example: is it possible for a wing-boat to sail directly downwind on a run? Is it faster to sail on a reach, even if the wind is directly towards ther next mark? The dynamics of the whole thing are NOT "the same as" the sailing Mankind has been doing for thousands of years! The foils, we hear too much about; the trim of the wing, not enough! Please! Do a piece explaining!

Is a fairly good start
@@WhatAboutTheBee -- A text piece explained that an airplane extends flaps to increase the surface area and more importantly: the convexity of the wing to create more lift. At higher speeds, the flaps are retracted for optimum flying, and the additional lift and convexity are not needed. Since a wing-sail is an airplane wing shape stood upright, greater convexity or "camber" is used in lighter wind / lower speed, and less camber at higher speeds. I watch a few races, looking specifically for that, and it appears to be the case. Granted, in a plane, you get an updraft pushing higher, and the converse, but the long sought after principle that makes an airplane possible at all is the convex shape of the wing which creates a relative vacuum around the upper surfaces, thus "lifting" the plane. It's a known phenomenon that a plane will lose speed nose-up and tend to correct by going nose-down, will then gain speed, gain lift, and tend to nose-up again.
But the text I read left a lot unanswered, unexplained. I can see why (as someone asked) there is no spinnaker. A spinnaker would block the airflow back over the wing. A conventional sail boat could hoist a spinnaker and set the mainsail perpendicular to the run of the boat downwind. But we will never see that configuration on a wing-sail. But ... but ... and but ... and I feel like a child asking the famous endless "Why?" question. Why is there a jib? Why does the boat sail faster than the wind? Why does it sail faster downwind (if the whole thing is about airflow over - not behind - the wing)? Why does the boat have no keel? And the "How?" questions .... how much "push" is provided by the wind against the jib? How do the rear foils or rudders provide such resistance that no keel is required? Is it true that the wing-sail or winged-boat can sail so much faster than the wind because increased airflow provided by the boat's own forward motion adds lift? Would a hang glider, or a glider, or a wing-suit be a better analogy to a wing-boat than an airplane analogy?
There seem to be various dynamics at work, and there are engineers with their very own wind tunnels (who wouldn't want to have their own wind tunnel in their garage?!) and millions of bucks of testing on these designs. Somebody understands all the details, and could explain the main component parts and functions - please? We are not stupid.
@@davesmith5656 I totally get what you are after, but in order to obtain a really good understanding, my thoughts are you would need to have mastery of *fluid dynamics* just to start. Probably at the PhD level, with the ability to model and simulate the interactions.
I share your enthusiasm and quest for knowledge, but not to the level of designing a boat!
The difference between 'when I do this, the boat does that' and the physics of how these two fluids (air + water) interact with the boat surfaces, are two very different levels of understanding. One comes from years of experience, the other from years of study.
By the way, if you look at the first race of America's Cup 33, the wing sail stands alone, they do not utilize a jib! Still crushed Alinghi 2-0.
As to why the F50's do not need a keel. The righting moment is provided by the variable canting hydrofoil.
I really am impressed by the F50s. Marvelous to see in person and in video. They have a fan in me.
@@WhatAboutTheBee --- Thanks for the answer about the variable foils - I thought the winged rudders were doing most of the resistance work. You also touched on one of the other things I was puzzling over: how fast can the boat go, increasing airflow over the wing and lifting, until it hits a balance of resistance against the water and the aerodynamics of the boat? But what I'm really gunning for is to get the announcers or video makers to learn something they can tell us about the sport. E.G "Japan has their wing nearly flat! It looks like they're very happy with the 38 knots they're doing! And they're reaching at 32 degrees to the wind direction! Joe, tell me, is that an optimum for the class, or did Australia gain more when they sailed at closer to 45 degrees?" "Well, Jim, Australia had the advantage of the wind direction being a bit further off the mark on that leg - the 45 degree angle, generally, allows for more airflow over the wing." (I have no idea at all about which angle either to or away from the wind is better!! There is a world of new "do this / get that" in wing-sailing that is simply not the same as conventional sailing. If some of the guys doing interviews would ask the trimmers, it would be very interesting. E.g. Do you know if the rudder turns along it's entire length, or if it has only a section, like an underwater aileron, that moves?) I tired gluing a small piece of plastic at a 5 degree downward tilt onto the keel of a toy sailboat, and that just totally messed it up! I wonder how much the crews understand about how the boats work - not the design, but the skill of sailing them - which opens up an entirely new competitive world of gaining more wing-foil-knowledge than the next guy. It's nice to hear about and see interviews with the crew, but it would be even better if we were given more to understand about what they're doing besides lookin' good.
Hi Dave, youu asked about the rudder(s). Unless I am mistaken, I believe they both turn, simultaneously, along their entire length.
Slingsby was a tactician aboard Oracle Team USA in 2013 (foiling cat) and 2017 (foiling cat similar to the F50s of SailGP.). He currently helms for AUS.
Similarly Outteridge was on Artemis in 2013 and 2017 in AC. He currently helms for JPN.
Is it any wonder that they sit atop the standings? 'When I do this, the boat does that'. Experience counts, your point is completely valid Dave! My prediction for the SailGP finals is JPN v AUS.
The female announcer (who's name escapes me. Shirley?) seems to know sail racing, but obviously lacks experience in an F50. She is our best hope for in depth conversation on race day. I think the male announcer doesn't know much at all. Just a talking head. Getting someone to announce the race who is knowledgeable about F50s is going to be hard. There just aren't that many and of that lot, few are available to SailGP.
Yea I’m gonna be honest the penalty system should be time penalties just like any other race also I had to look up why teams are getting penalties in the race highlight shorts when they get dive bombed and this didn’t help as no one knows what the wind is when they watch so it’s just ope they got a penalty while being dive bombed you do that in f1 and its nothing so long as there’s no contact maybe 3 seconds for contact, violate the track limits which are actual lines on the ground well that’s more time against you at the end. Also super punishing a team for a false start is ridiculous. While everyone else is super speeding they have to basically dump all their speed and wait for everyone before having to hope they can catch up
I found out that if a sailboat racer is way too close that you can hit another sailboat racer at the start, you can get a black flag penalty - and that sailboat racer who almost caused the collision is DISQUALIFIED FROM THE RACE!
This is what happened to the Switzerland team in Race 1 at Cadiz, Spain, in the Spain Sail GP.
This is a very strange video. I understand how to get penalties, but I have no idea how to win.
First off that music, damn. And second these rules suck! It's a RACE so basically you can be in the lead and still lose to crybabies because your too fast?!
Clicked for the rules. Stayed for the music.
How many Joe public know about rules- they watch state of the art high speed racing \F1 - SailGP/ as entertainment. You rule makers kill the sports “ shame on you”.
rulemakers are what make a sport a sport lmao without rules there wouldn't be competition, go watch yacht shows buddy
Music is so loud
