As the world awaits the big decision on what the AC75 monohull will look like, the man at the center of it all talks about the potential concepts and the details on how Emirates Team New Zealand crushed the world in Bermuda.  Here’s 10 minutes with ETNZ Design Coordinator and former Formula 1 Vehicle Dynamics Engineer (McLaren) Dan Bernasconi from Radio NZ.

Concept 1 “…a fairly conventional but high performance monohull…”

Concept 2 “…a semi-foiling monohull…”

Concept 3 “…is it possible to get a really big yacht fully foiling. The sailors who are listening will know about foiling Moths which are single-handed fully foiling boats which are great. But on those you use a lot of your body weight to balance, and that is something which is really difficult to scale up.”

Discuss the three options for the next Cup in the thread.

In a move that’s been telegraphed since we first reported on some of the inter-team intrigue while in Bermuda, Luna Rossa boss Patrizio Bertelli announced in an interview with La Stampa yesterday that America’s Cup 36 will indeed end the reign of the America’s Cup multihull in favor of something significantly slower.  ETNZ was forced to send out a confirmation of the lead-assisted future after Bertelli broke the news, explaining that ETNZ design coordinator Dan Bernasconi has been working on a number of ‘exciting monohull concepts’ with potential challengers and designers .  The Kiwis maintain that the new Protocol will be available by the end of September.a

The decision is as depressing as it is exciting:  The last three cycles have seen more innovation in high performance sailing than in the previous 30, with the Cup going from a dopey exhibition of obsolete design and sailing technique to an honest-to-goodness extreme sport whilst dragging the entirety of the sport along with it.  Consider: Without the DoG battle, there’s no AC72.  Without the AC72, there’s no foiling multihulls and no L/J foils.  There’s no foiling A-Cat, no GC32/EXSS foiler, no Phantom, no foiling Nacra in the Olympics, and the monohulls aren’t immune to the effect; the foiling IMOCA/Volvo Super 60 owes its existence to the ETNZ innovation.  Literally every exciting development in fast sailing since 2012 has come directly from the AC cats, and their inclusion in Sailing’s ‘pinnacle’ finally gave credibility and respectability to multihullers – sailing’s redheaded stepchildren for a century.

On the other hand, with the true 90% ballast ratio’d leadmines finally dead and buried, the new focus on what we expect to be an upwind-and-downwind foiling monohull may drive a new age for monohull sailing, and that’s something to celebrate.  For far too long, the Moth has been the only monohull foiler to set the world on fire, and a few hundred million in development could work wonders towards bringing their level of performance that much closer for the average dinghy or (lightly) ballasted monohull.

So what will it look like?  We’d love to think it’s wide open, with the ETNZ board and Bertelli’s management allowing all sorts of development variations.  Centerline T-foils, mixed horizontal and vertical appendages, powered control surfaces – all the gadgets.  Unfortunately, that ain’t reality, and there’s no way Dalts is going to give away his biggest competitive advantage – Guillaume Verdier’s knowledge of big monohull foilers – by allowing an outlier design the room to shock the world.  Look for something like the Volvo’s Verdier design brief, but with lighter weight, more appendages, and a clever control system. We expect AC36’s racers to look far more like cats than any monohull you’ve ever seen.

Rambler

The Rambler 100/Speedboat keel that nearly killed more than 20 sailors during the 2011 Fastnet has finally been plucked from the deep; will the world of yachting finally get an answer to what caused one of the most ridiculous and potentially deadly accidents in recent memory?  We’re not holding our breath.  Photo via West Cork Photo’s Facebook page.
