yep it looks so. I was hoping that Prada would bring some kind of a "new cool" with a bright color, like they did with the silver boats in Frisco...
We'll see tomorrow.

Paint =  weight that can be more usefully employed elsewhere. Ensuring the outer/epoxy/varnish/whatever is UV stabilised has been sufficient on other boats so likely more than enough for a molly–coddled AC hull. ;-)

It also ensures the boat builder makes the outer hull has fair as possible with no filling so more weight saved.

I think vinyl wrap for advertising is not included in the weight of the boat, so covering most of the hull in sponsor wrap is a pretty good alternative to paint.

Isnt there a rule about the type of finish/paint required. Standard 2 pot? Basically so the teams dont spend mega bucks on surface coating technology (sharkskin texture etc etc)

Looking reasonably full in the bow, foil mounts look halfway between the very potruding AM and very recessed ETNZ, yup probably yet another different interpretation.  Can't wait for the full reveal so we can see what the underside looks like.

I'm pretty sure the black is just plain carbon that's been given a matte finish, no need to paint it black if it's already black.

The Foils well.....I’m trying to like....but just can’t.

[RobG 753]

Each foil has to weigh close to 1,000 kg. Presumably LR has put most of that into the bulb, leaving them a lot more leeway on materials and design of the wings. It may also mean they can easily swap wings rather than the whole foil.

There may also be benefits for cavitation, and at least one very knowledgeable and successful hydrofoil builder swears that bulbs are faster than T joints, all else being equal.

The aggressive anhedral of the foils helps to open up the superposition region where cavitation may be an issue. The tips seem to compensate for this and maybe return some roll stability. 

The keel continues to just in front of the rudder. Doesn't look maneuverable in displacement mode.. wonder what the advantage is.

[Xlot 830]

Minor remark: apparently, Italy doesn’t share the US requirement that a painted flag should have the staff side toward the bow. So, on starboard the staff (green) segment is aft - had noticed that on a previous LR boat

 

OTT, I see absolutely nothing that would jusify Max Sirena’s claim they delayed launching by one full month so that the competition wouldn’t copy them ...

 

[The_Alchemist 1,256]

I see they have the torpedo foils.  Could have delayed the launch after seeing the AM foils!  They can only splash 6 foils and may have realized the NZ type foil was inferior?

[tinga 15]

fences on foils.

[theParadoxOfThrift 13]

Three super-high quality boats launched - amazing effort from these teams interpreting a new rule.

ETNZ are an outlier in respect of their foil design.

AM do not have the bustle - a more aero hull.

It will be really interesting to se the next iteration of these boats.

Torpedo not a foil. Can't see the point unless to add some lead ballast or as structural support for the foils.

Do the Italian foils have less area than TNZ and AM. Seems to look like it.

As for hull shape if the aim is to sail the majority or all the race flying, then the Italian hull looks like more drag.

Also surprised that they are not using two different foil designs on either side. With the limit on the total number allowed seems a sensible  choice by TNZ

[hoom 567]

*ahem* I'll just leave this here

*hack splutter*

I thought it might be more subtle but didn't pick a sharp ridge like that

 

I feel that the idea of the central bulge must have been a concept that was shared one way or the other between TNZ & LR.

Maybe from personnel changes or as part of exploring the shapes possible within proposed rules?

[Stingray~ 1,405]

from https://www.sail-world.com/news/222696/Americas-Cup-Luna-Rossa-launch-first-AC75

The Challenger of Record for the 36th America's Cup, Luna Rossa Prada Pirelli has launched their first AC75 in Cagliari, Sardinia.

The hull is a different design treatment than the first two launched by Emirates Team New Zealand and NYYC American Magic. The bow is reminiscent almost of an IACC yacht, with a very soft treatment, however about a third of the way back a crease starts in the hull which appears, from the video to develop into a bustle coming into a skeg-like structure in the centre of the transom, ending just ahead of the rudder.

(contd)

This will be a very interesting cycle.

Like the first cycle of the IACC when we saw, "short skiffs" (TNZ), "heavy/long/narrow" (USA) and the "aircraft carrier" (ITA).....

we focused more on hydro-dynamism than on aspect of air performance ".

Hydrodynamics - the motion of fluids and the forces acting on solid bodies immersed in fluids.

Does this mean the Italians think the hull will be in the water more than the other teams?

Are you sure about that?  The LR foil looks more like a couple of fins stuck onto a symmetrical bulb.  The AM foils look to have a very intentional design that looks more like a bird in flight with flaps.

Which makes it interesting that LR launched with 2 identical foils, apparently and assuming they are real.

Perhaps, since they like AM have torpedos, they can do a lot with fins because of how much weight is concentrated in them and could remain unmodified? edit: I see that was pointed out above already
