Bundy's quote: Everyone is grinding, the boat is so physical and because everything is happening so fast as well, everyone just clicks in and grinds it in. Nobody is really just dedicated to one role. All the grinders can switch into everyone's winch so they can switch back and forth. So for a hoist or something they can all just click in and grind.Source and good read!
Artemis' Cayard: “We have 38 hydraulic cylinders. We want to avoid running hydraulic piping to each of them, because that would be heavy, so we have electrovalves embedded in the wing to actuate the hydraulics. But if you had two wires, positive and negative, running to each electrovalve, your wing would look like a PG&E substation, and that’s heavy too, so we use a CAN-bus [controlled area network] with far fewer wires. Still, it’s incredibly complex.
“We wind up with lot of hydraulics,” Cayard says, “and the America’s Cup rules don’t allow stored power, so two of our eleven guys—we think, two—will be grinding a primary winch all the race long. Not to trim, but to maintain pressure in the hydraulic tank so that any time someone wants to open a hydraulic valve to trim the wing, there will be pressure to make that happen.”
ETNZ's Rod Davis: "There are eight grinding pedestals, 30 buttons to change linkage to drive different winches (twice as many as the old boats because you have two hulls to sail from), 190kg boards to go up and down, hydraulics that make an big jet aircraft look like a kids toy - and the boat is 46ft wide"
