FIRST WOMEN’S AND YOUTH AMERICA’S CUP INVITATIONS ISSUED

Set to be stand-out global events, the Women’s & Youth America’s Cup Regattas are two of the major highlights of AC37 in Barcelona, shining an intense spotlight on the next generation of America’s Cup sailors. It is the ultimate showcase for tomorrow’s household names and superstars of the...

The format for the Women’s & Youth America’s Cup events is set to thoroughly test the athletes with a mixture of fleet and match racing. Where possible the fleets will be split with the confirmed teams for AC37 forming one pool for each event and the invited yacht club teams competing in another pool. The racing initially will be three fleet races a day for three days and then the top three teams in each qualify for a four-race series amongst the top six teams to decide the top two. These successful teams will then go head-to-head in a classic match-race, one-on-one fashion to decide the outright winner of each event.

Good lord. This is absolutely insane.

You brought up SailGP. And yes, the danger is absolutely there too. I recognize that.

But first think about who is sailing those F50s - and the amount of OTW training time all new teams get in them prior to racing. How much OTW training time will these “invited” club teams get in the AC40s prior to the actual racing? Look how slowly the build process is going! THESE sailors will be the sacrificial lambs.

Then, actually more importantly, think about the technology already in place for monitoring the boats with SailGP (what you see in the Ump view in the app, etc.). I haven’t seen anything even remotely close to that with ETNZ.

With that kind of technology, and these AC40s being on AP, you could conceivably build in automated safety zones. It would make all kinds of sense. But, again, all we are seeing from ETNZ and Bernasconi is ridiculous spin about how awesome these boats are on every level - sweeping the clear dangers under the rug for the sake of marketing.

Yes! Would love to see that, have suggested it before. Maybe even add intelligent obstacle avoidance sensors with feedback into the steering.

Absolutely. Or enforce all foils down in the box. Then on the course, if a potential collision is detected, the lifted foil automatically drops. That would be a hefty penalty in terms of speed/time, but at least it would provide some level of survivability.

But again, I can see that happening in SailGP with its tech. But you saw that last AC and the lackluster technology ETNZ had then. Do you think they could pull something like this off?

There was a legal problem last time when ETNZ/ACE tried to use the same LiveLine technology SailGP uses, without paying for it. Think that got resolved.

Yes, the foil drop idea could be a good one.

I’m not sure what all is in the LiveLine package, but I thought that was mostly for the TV sync and overlays?

I‘m talking more about the umpiring telemetry and application SailGP has. That thing is off the charts amazing.

And as for the foil drop, if it happens - you heard it here first.

BTW - there has been a lot of speculation as to what the AC40 auto-pilot will/won’t can/can’t control. But if you look at Bernasconi‘s own business site, here is what he designs and builds for…

AUTOPILOT DESIGN​

SumToZero is experienced at using the dynamic modelling capabilities of Gomboc to develop sophisticated autopilots for displacement and foiling yachts, including IMOCAs, several AC race and test boats, and smaller craft. We have developed a number of autopilots, for instance:
  • Helm control: Single input, single ouput such as steering to a heading or wind angle
  • Helm control: Multiple input, single output, combining multiple sensors to steer the yacht optimally in waves
  • Helm and sheet control: Multiple input, dual output, controlling helm and traveller or mainsheet to achieve target true wind and heel targets
  • Ride-height control: Foil flap or rake control to achieve a ride-height target
  • Flight control: Multiple input, multiple output: Fully integrated control of foils and rudder rake to achieve stable flight
    +++++++
So, yeah, good telemetry and this AP could likely automate enough control over the boat to do just about anything - like avoid collisions and save lives. The tech is there. The question is - will they do it? And if they don‘t, at what point does it become negligence?

This also begs the question of exactly how much actual input these YACnSCAC sailors will have on AP. We’ve seen the buttons, toggles, and knobs in Nathan’s vid. But very little detail on how much control they actually provide (remember he did say some are stop-limited). Judging by the above, the AP could handle essentialy everything. Is that actually what’s happening with these boats for the YACnSCAC? If so, any goofball could be in those seats…even enigdos.

So what’s the point again?

No worries SBD. If some of the chuckleheads around here would actually put a little effort into being somewhat informed before they spout off, they wouldn't look quite so foolish.

Of course, with my record of being proven right (yet again), I suppose they can just continue to sit at my feet and learn.

Heh.

NZ could raise money by having raffles or auctions for "a seat at the wheel" on AC40s. No skill required, preference you don't get seasick to reduce cleanups between seat-winners, er, drivers, er spam at the helm.

Actually, you’re not far off Clew. The YACnSCAC is essentially going to be this…

Except at 60 knots with giant sling blades whistling toward the passengers‘ heads.
