A couple of years ago I did some work with the folks at Zoomslide for Team New Zealand. The decision to hold the 2017 America’s Cup in Bermuda was still fresh, and so was Grant Dalton’s language describing it.
Here’s what I like about Dalton: he’s at least the world’s second best America’s Cup CEO. Sure, he’s had some bad work days, and earned himself a few critics. But let’s say you wanted to win the America’s Cup. You’d have to talk to him: he’s got more experience in that particular domain than anybody currently outside of the Oracle camp.
He wasn’t the only one taken by surprise. Cynics – which the America’s Cup has always had in droves – reckoned it was chosen simply as a hard-to-get-to location, hitting the budgets of all the other teams harder than it would the American defenders. Who knows how much truth there is in that.
But now the challengers are arriving and launching their kit, and they (and others) are posting video of themselves hooning around the Great Sound in their foiling catamarans. Whatever logistical challenges Bermuda presents, the Great Sound appears to present a reasonable stretch of flat water and steady, predictable trade winds.
Back in San Fran, wind and waves contributed to both Oracle’s capsize and ETNZ’s nosedive. The new boats represent a massive development. The old ones were 72 feet: these ones are just 50 feet. But the new ones are also faster, spending roughly the entire race up on hydrofoils. That means they’re also much more precarious: the chance of a capsize is high, at all times.
To put that in perspective, consider the 3m Moth class, a super fast single-handed foiler. If it hits the “wrong” sized wave, the foil simply pops straight out of the water, leading directly to a capsize. Scaling that minuscule and highly probable error up to a 50 footer at 40 knots (about 70 km/h), flat water is probably a legitimate safety concern.
Regardless, they’re still capsizing. Oracle tipped out a couple of weeks ago. And Team New Zealand got pretty close to it this morning NZ time. This is good for two reasons. First, it means the boats are more interesting. Second, it means those teams will have a better knowledge of their performance limits when racing starts on May 26.
I heard some gossip about ETNZ’s peddle power. The peddles (and grinders on other boats) generate hydraulic power, which is then used to make frequent, rapid and minute alterations to the wing and foils, which are under enormous loads.
The picture painted by the team, the other crews and the media is that there’s a trade off: pedals yield more power, but are less convenient, taking longer for the crew to clip in after moving about the boat in manoeuvres.
But there may be another advantage: with pedals, several sets of hands are freed up from grinding duties. It’s not inconceivable that the crew can trim and grind at the same time.
It seems likely to be in the rules for grinders to produce other forms of stored energy, such as electricity. That means they could grind with their feet and control numerous aspects of the yacht through a touch console, such as luff tension, foil attitude and sail position. That’s a rumour, anyway.
As with the 2014 AC, foiling and wing trimming will dominate this event, but in a different way: a lot will come down to cornering. All crews are now foiling in all directions in straight lines, upwind and downwind. All crews are now foiling through nearly every gybe. But only some crews are foiling through most tacks. All crews are still developing this skill, especially in the lower wind strengths. Everyone will want to be the team who can tack on foils in the lightest wind, like this (links to a sequence at the end of the video):
So, my predictions? The Swedish team Artemis dominated a bunch of informal practice races that took place shortly before ETNZ turned up last week. They look fast and stable (and fast because stable). The American team Oracle and British team BAR are probably the next in the queue, followed by the Japanese in SoftBank and the French in Groupama.
ETNZ is a relatively unknown quantity since they elected not to take part in the first round of practice races. But we know they’re among the most efficient foiling experts (hell, they practically invented it within the AC), keeping good speed and stability through most tacks in any kind of breeze.
I like to recall that in 2014, Dean Barker of ETNZ (now of SoftBank) consistently out-sailed Jimmy Spithill (who’s still with Oracle), until the lay day allowed Oracle to make some game-changing alterations to their boat. Check out the start of race 1 in San Francisco. Since his unceremonious departure from ETNZ Barker has transformed team Japan and will have several points to prove over both Spithill and Dalton.
Meanwhile, ETNZ helm Peter Burling has totally ruled over Artemis skipper Nathan Outteridge in the high performance 49er class for the last 4 years, winning every single event, including a comprehensive Olympic gold. He also beat Outteridge to #1 in the Moth world champs. So it’s not unlikely that ETNZ will prove tough to beat.
Now all I need to do is figure out the minimum deal I can strike with Sky to watch the darn races.
