It is being pedaled..
Watching the America's cup match races from Bermuda , on TV, and noticing the NZ/UAE boat has the grinders
on their boat , pedaling, where the other boats, Japan in this case, using the more traditional arm (2 guys) powered crank.
pulling lines, changing the (wing) sail deployment with the Capstan /winch..

Match Race , between just 2 yachts.
They look quite busy, head down, working hard, not looking around .... they're not steering .. Helm's another guy..

The America's Cup rules don't allow engines on the boat. Everything has to be manually driven. So, to get enough oil (hydraulic fluid) flowing through the boat they use rotary pumps, which are 'usually' linked to the pedestal grinders. The grinders are essentially pushing oil throughout the hydraulic system the entire race. Any time they want a hydraulic cylinder to move—whether it’s in the wing or in the daggerboard system, a headstay, or jib cunningham sail, it needs oil for the hydraulic-powered wenches. Instead of the customary grinders operated by hand, New Zealand is using pedal power. And, they have recruited Olympic bronze medal-winning cyclist Simon van Velthooven to lead the new revolution. Although the entire crew can man the bikes.

RI certainly is closer to the kind of top level Yacht competitors , than we are, out here..
So I've not read the Rule book, thanks..
Does kind of look like the team pursuit race going on .

I'm surprised it took them so long to arrive at this solution. More power (legs vs. arms) means faster sail trimming, means valuable milliseconds.

Yes, what ForceD said.
Legs have more power than arms - so in theory the NZ boat has more hydraulic power available. The trade off is it takes a couple seconds more each time for the crew to get into position on the pedals, vs the arm grinders. I guess the question is whether or not having the extra power available will matter. So far it seems all the boats have enough to sail the course. If they got into a tacking duel or another reason for lots of maneuvering, the draw on the hydraulics could give TNZ an advantage.
Fun stuff, they've made it exciting to watch. Lot different from traditional sailboat racing.

Well, it may have been in the past that all the teams involved in the America's Cup didn't agree on their inclusion. Living in the Newport, RI area I actually do crew for some sail yacht racing, and I've read the America's Cup rules. The thing is...those rules can and do change from America's Cup to America's Cup. When the original rules were established there was a clause included that said the rules can change as long as all teams agree on it. And then the next year it can possibly change back.

Now I see the downside:
The trade-off is that it’s harder to get from one side to the other in a maneuver, getting on and off the bikes

the summer racing season is going, and there are more to come, I saw some of the various match races on NBCSN.
