Prada | America’s Cup Technicalities

Fusing athleticism, teamwork, and technology, the monohulls competing for the America’s Cup are the fastest in the world. It was August 2012 when the sailing world was turned upside down by a 72-foot catamaran flying in the Hauraki Gulf. Emirates Team New Zealand had brought the foils to the America’s Cup boats and forever changed the face of top-level racing boat competitions.
Since then, the increase in performance for America’s Cup boats has been greater than at any point in the 170-year history of the event. Six years later, in 2018, the publication of the AC75 Class rule marked the beginning of a new sailing era. Now, foils are commonplace, but the engineering and sailing techniques needed to get the AC75 to fly completely differ from anything seen before.

[@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.

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.

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? It seems very silly (a nonsense).

Same here. These are so fun to watch with outrageous speeds. But the races are over so quick. I was on the water in 2000 in NZ with traditional monohulls. This lasted about 2 hours and you could follow from mark to mark. Not anymore.

[@alikindo5819]

Prada toujur prada❤

[@petert3355]

Here is what I don't understand. Last Cup, one team changed the grinders from arm crank to leg crank. Makes sense as the legs are the biggest most powerful limbs in the human body. Forward to current Cup, I see everyone is back to arm grinders. Why?

[@tolissailor]

There was a change in regulations and it is no longer allowed. I guess since they won, they reveiled their edge, so there was no reason keeping it there any more, since all would copy in the future.

[@danielweston9188]

Interesting enough the Leg system is heavier and for the new foils weight is everything.

[@swobst]

Great video, Musik to loud!

[@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

They are turning hydraulic pumps to keep the system pressurized, this hydraulic power is used to alter trim, sail shape, back-stay tension etc.

@@johnharrison2741 Is that correct? The video said the hydraulics are battery powered. So could they be turning generators to charge the batteries, not turning hydraulic pumps? I've not been able to get a clear answer about this.

[@johnharrison2741]

@@douglasburnside I am no expert, but as far as I know the foils and rudder are powered by batteries that power hydraulics for this system only. Everything else (above the waterline) is powered by humans turning pedestal grinders, that provide hydraulic power on a separate system. The hydraulic power is stored in accumulators, so that it is available to do multiple functions on demand and re-charged when there is low demand.

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? Since these are essentially power boats why can they compete in America’s Cup? I’m genuinely interested in the reasoning as to why this is allowed in a sailing race.

[@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...
