When you have the budget to build a boat like that but then can't manage to find someone to fix your auto-generated subtitles.

[@jimhood1202]

Ok, so the foils are lifted and lowered by battery powered hydraulic rams. Presumably the controls of mainsail, jib etc are also hydraulic, are they also a component of the battery powered system? If so, then are the grinders simply replacing the battery energy used by the hydraulic pumps by turning battery charging alternators or dynamos? How long can the batteries power the hydraulics without being charged before they run out of power? Must the boats finish with fully charged batteries? The grinders are obviously working hard almost all the time I'd love to know how the whole battery, hydraulic, charging system works. Does anyone know of of a web site or video that explains it?

At a guess you would have multiple sonars to detect the heights and gyroscopes combined with accelerometers fused with software like an extended Kalamn filter. This would control the flaps to maintain lift, pitch, roll and more.

[@BluesAlmighty]

The upper foil surface longer than the lower in the elongated droplet shape assists the laminar flow, but is not the main reason an aeroplane or the AC75 flies. It is the angle of attack of the foil towards the direction of flight that creates lift. Think of a simple kite with nothing more than a single plane keeping it in the air, just like the first stick, wires, and cloth skin aeroplanes could, or a paper folded aeroplane can fly. Amazing machines those AC75s have become! I just find it a pity that it became accessible for even less teams. I hope to see more teams than just four competing in the next America's Cups to come

I don't understand much about sailing but I follow the America's Cup for many years (since first italian challenger Azzurra) and I don't understand some controversies I've read (about the boats); too many people are nostalgic, they say that these boats don't sail but fly, talk about the dear old boats, the "true" match-races, the Spinnakers and bla bla bla. I'm not more a guy (unfortunately I add) but I really don't understand, time passes, everything evolves *(not my eng, sorry)* because this shouldn't happen for sailing and (firstly) to the America's Cup?

If the cantilever arms are run by batteries, why have those idiots playing patty cake. Replace them with batteries. Or at least replace them with a bike mechanism, so only one is needed, instead of two.

[@stevenzhang199]

"Whilst the batteries control the main foils and rudders, everything above the waterline, including every sail control, is powered by the onboard grinders using pedestals supplied by official Winch Systems" - www.ineosteamuk.com/en/articles/271_The-grindhouse-rules-powering-the-AC75-with-Harken.html

[@AntonGudenus]

I think they wanted to keep the illusion of it being an athletic sport and not just an engineering and driving battle. And to make it look like they are still pulling ropes to trim the sails (which they definitely don't) Realistically each of these guys can output a maximum of 300W of power over a time of 3 hours (could hit 400W if they were to use their feet instead). So to replace them with a battery you'd need one with a capacity of about 300(watts)*8(grinders)*3(hours)*3(safety factor)=21,6kWh, which would weigh about 90kg with modern battery technology. Thereby saving close to a ton of weight (both the grinders and the grinding fixtures)

i still not fully understand these sail racing boat how it work, i understand how to lift work, but how to use wind and sail to make forward movement and go freaking fast like a moto powered speed boat??if i rotate the boat 45 degree to look it, is easier to understand??so if take the all part off the boat , but only have that big main sail, when wind hit main sail, create uplift force like a airplane, in theory the boat will keep running circle right?? sorry for my poor english.

[@randomwalker332]

A simple explanation is like this: an airplane wing installed on a plane in horizontal position, and when the wing cuts through air, an artificial wind is created which lifts up the plane. Now if you install the same wing on a sailboat but 90degrees up in vertical position, what do you expect? There is a natural wind blowing into this sail, the same aerodynamic effect would now push the sail/boat forward instead of upward (remember the 90 degree change in angles of the same wing), as simple as that.

This is not a flippant comment but an honest question. Why are powered hydraulics allowed? Why not just put a screw on the back and do away with the sails?

[@jg-tz4fn]

@Charlie Manning Why have grinders then? Clearly some parts are allowed to be electronically controlled and some not.

[@smartcatcollarproject5699]

Because it's the only way to have these foiling boats racing in a traditional regatta today ? I'd bet they didn't want to miss that opportunity, and without this trick it would be too slow to move the foils up and down and impossible to tack "on the wing". Of course you can argue about the rules, or if a human crew is really needed at this point. A few cups ago the AC boats were quite lagging in their general design, with heavy keels, etc but the most recent competitions are going to the opposite extreme ! Maybe the next AC could be a regatta of drone-boats, without crews, piloted only by AI skippers...

[@gerhardkutt1748]

They have the foil explanation wrong. The foils lift due to the downward force of the water flowing over them and downwards after the trailing edge. There is NO pressure difference because water is incompressible. As a foil boat designer myself, the wing acts more like an aircraft in supersonic mode, but without the pressure cone. The foil will reach height equilibrium below the surface of the water once it gets close to the surface at around 1/3 chord where volume of water flowing over the foil that creates the downforce at the trailing tip at speed equals the weight of the boat and wind forces acting upon it. The foils that can maintain laminar flow over the foil and the T section and minimize tip vortices with the smallest drag will win the Americas cup, along with the hull and sail design to trap air over the entirety of the boat from keel to top of the mast. Boats that have the lowest foiling speed will win. The foil singing is created if the trailing edge is not sharp and also by strut singing, where the strut achieves resonant frequency. The rudder and forward foils will sing at different frequencies. If they have designed the wing like an aircraft wing, they will lose! The foil cross section for water is very different to that of an airfoil. Because an airfoil in water will cause a LOT of turbulence and will not work properly. The best foil design will be flat and not have a complex shape, as complex shapes will increase the chance of turbulence. Extended pointed skinny bulbus T sections forward of the leading edge will allow for laminar flow over the leading edge which is crucial between strut and foil. At best the strut should start behind the leading edge of the foil by at least 1/4 chord. The New Zealand boat has the best foil design. The Italians come a close second with the Americans and the Brits have a lot of work to do on the design of the boat and the foil, because they cannot get on foil at low speeds. They need increase chord to increase lift, change the foil profile and curvature - test in flow tank and measure lift vs speed - watching attack angle. Neutral foil angle setting is critical and is sensitive to 0.2 of a degree for the forward foil. I would make the aft rudder foil with changeable angle of attack as the aft foil will affect the forward foil and has more room for attack angle variance. Varying the forward foil curvature will affect resistance and lift and is VERY VERY sensitive at higher speeds.

[@NGC1433]

No pressure because water is incompressible? Run telling that to divers, they all are suffering the bends in vein. As well as all the submarine hulls should be replaced with camping tents wrapped with polyethylene film, because there is no pressure! Water does not change in VOLUME with pressure changes.
