For those of you who wanted Alinghi back, be careful what you wish for…

Great to see that Dean may have another opportunity training up some new AC athletes. Dean struggled in the starts, struggled with the handling of the boat, capsized an AC75 and didn't win a single race that actually mattered. Barker/Botin/Arrivabene - It doesn't sound strong BUT maybe THutch was holding them back or just f'ing everything up.

Slingsby - he will land somewhere at some point. Maybe he will be someone's May Day Basket

I pointed out Dean's return to AC37 w/ Alinghi back in April.

Would love to see anyone post some foil comparison photos.

Am guessing the rules are complicated?

Starboard foil looks like ETNZ W3 or W4. The foil that was on the starboard side for ETNZ at the Christmas regatta. The one with the blended bulb. The other in this pair had less fairing between bulb and wings.
This is also the foil that has the strip of flexible material joining the flaps on either side, which you can still make out as a slightly lighter patch in the centre at the rear.

ETNZ cup foils were skinnier still, and had a noticeable gap between the flaps on either side. The etnz cup foils also appeared to have some anhedral when out of the water not under load.

The port foil looks like on of American Magics foils from Patriot. So, it would be interesting to have those two foils on one boat for A-B testing. If, and it's a big if, it's an AM foil, then it will be interesting how that plumbs in to the ETNZ foil control systems.

Anyway, these foils, and seemingly arms aren't like the new rule. I think from a tech perspective this is a full scale size mule for crew training. And maybe building up a data pool with these two contrasting foils styles from the previous AC.

so now we get back to the recon rules. stuff is going to hit the fan quickly if teams feel like they are not getting the correct amount of information from the Recon Group. I am going to bet that teams have a recon person tracking the personnel of the Recon Group

The teams provide / appoint someone to the "Recon Management Panel" under the rules of the technical regulations to manage the shared recon.

Starboard foil looks like ETNZ cup foil, or close to the cup iteration.
Port foil looks like a test foil with larger bulb. More like LR / AM / INEOS first foils.
I know this is a roll out of the first kiwi boat, but I was hoping there would be at least a few rudimentary conversions to see which give us insights about the new rule... but not much I can see.

have looked at the image for at least 2 minutes, so don't take this as fact but
1) the foil arms don't look longer (hard to tell)
2) foils look like a crude test foil to run against a 'know quantity ETNZ race foil'.
3) Not set up for bikes
4) Are the wings even made to the knew geometry? Wider span? Don't look it, look like reuse of old foils.
5) even the redundant bowsprit is on.
6) 2018 rang, they want their backstays back.

I only had a quick read of the TR but my understanding is that any legacy (from AC36) component must have a version A that is in a measured configuration (from AC36) in order to be counted as such (thus presumedly not take up a component of the new boat), so would the bowsprit not be part of the "hull" version A from AC36? and then theres a couple of specific extra rules like:

4.9 The hull lower surface of a legacy hull cannot be modified; changes to the hull surface of a legacy hull
shall be confined to the deck.
Click to expand...

With the "immutable" area being 87.5%, so any later removal of the bowsprit would count towards that?

4.10 The second and third new AC75 Class Yacht foil wings declared by a Competitor must have an identical
Version A design to their first declared new AC75 Class Yacht foil wing. Those second and third new foil
wings must also retain the same immutable portion as the first declared new foil wing throughout AC37.
In particular the hull lower volume cannot be modified (only the deck), so are these foils not just original ETNZ foils?
Click to expand...

Plus with foils theres this rule that makes "derivative" foils have to be versions of the first launched new foil, so presumedly they are using legacy foils to avoid declaring a race foil?

I think you're spot on.
I didn't really think we'd see new foils or new arms at this point, but it's interesting to ID the kit they are sailing with. As it tells you a little about who is prepared to sell tech, and which tech they view as useful to buy.

To be honest I did think we would see a self tacking jib, back stays removed and cyclors. If their stated aim with this is to teach young crew how to sail an AC75, why not configure it like an AC37 version... maybe just getting the thing on the water is #1 priority and they can play with sail controls and crew stations in due course.

Further rule prevents new foils:

4.15 The following new AC75 Class Yacht components may not be installed on a legacy AC75 Class Yacht hull:
(a) foil wings;
(b) foil flaps;
(c) rudders;
(d) mainsail skins; and
(e) jib skins.
Click to expand...

Plus this may prevent removing the backstays?:

4.13 Legacy mast tubes shall only be modified from their AC37 Version A of the component within:
(a) the mast lower zone; and
(b) additional regions that may be defined in the mast specification.
Click to expand...


For the cyclors vs grinders, maybe the structure simply wasn't able to be altered in a way to may room for cyclors? (or prehaps just required more modification percentage than permitted?) Or maybe Alinghi thinks its valuable to gain experience with a first gen AC72 "as is" and not give away to much on a boat that is purely a "get up to speed" exercise?

That is a TNZ foil on the starboard and an American Magic foil(with the large bulb) on the Port.

I guess this makes sense, allows new teams to recreate experience other teams have had, but stops them getting ahead of the curve testing new stuff early.

It does devalue the old boats though, but perhaps there are too many differences in the rule to make upgrading a legacy boat in to a race boat for AC37.
