Hmm Some of you that have been around the waterfront a year or two may recall a certain single handed cat foiling on the Waitemata-- and he could tack on the foils -- early 80's . So don't be too surprised... And that was just a keen amateur one G Baigent no less.

Sure it wasn't David Knaggs?

No team has successfully foiled upwind for more that a few moments after a mark rounding. And in extreme bear away situations.

Yep Quite sure, David got his GBE going indecently quick for our speed trials with weight on stick out behind her, and many years later built his foiler quite a construction feat -- and once rigged something to behold.

Are you sure of that? How do you define "successfully"?

Quite a definative statement. Its lucky we have you around to tell us whats what.

 

I noticed ETNZ at one point this morning doing 27knots upwind. Certainly have the speed to foil.

 

I understand its just a VMG thing. In that they CAN foil 'upwind', but due to angles, may not be worth it.

[waikiore 399]

Clipper bang on the money.

[Guest]

They can foil upwaind, it's just they do 1 sideways for every one forward.... but that may have changed

In light of the video footage from the second race today where both ETNZ and Luna Rossa were shown on broadcast television to be successfully foiling upwind for extended periods of time, would you like to revise this statement?

Interesting vid, do wwe know what LR were up to at the time, because if you look at the srparation NZ was putting a huge distance on them.

[Guest]

LR were low and slow. check out the other video at the 2 minute mark

Morrelli’s hot on foiling as the way to go forward in all things AC. “Most people don’t realize we’ve been dealing with foiling for almost four years, before the 2010 Cup," he says. "We designed the Nacra 20 that’s been in production for five years now, that had curved foils; prior to that we built an A-Cat with curved foils. We’ve been building power cats for 15 years with foils. People playing with catamarans have been playing with foiling for a long time.” We caught up with Morrelli for his insight on the big picture of the AC72 design:

The 72 seems to be a designer’s dream and a sailor’s nightmare. How did you get to the boat we have today?

 

GM: Most of the 72 was dictated by Russell [Coutts] and the Oracle guys. After the 2010 Oracle campaign, they retained us [morrelli & Melvin] to do some performance analysis on different sized trimarans— a trimaran being the original contender with a soft rig. We did all kinds of analysis on things from 60 to 90 feet—cost estimates, performance estimates, and providing them with a matrix of options there.
