Luna Rossa Challenge. AC 36

[Boybland]

So won't the "keel" ridge make it damn difficult to turn when the hull is in the water?  Seems like things could get interesting if they splash down during a tack/gybe.  Kind of like grabbing an edge on your snowboard...

Not really, many boats have keels like that including almost all displacement mode launches.

It might not be the most maneuverable design to be sure, but it won't be that bigger issue once she is under way.

Could have implications in the start box I guess, but to be honest so might AM's very flat bottom with no keel for the rudder to work against, having only one foil down to leeward must make for intersting forces when trying to get the rudder to work when near to stationary, especially if the hull shape has very little lateral resistance, kind of like trying to turn a dinghy just after a beach launch, when your just drifting and before you get the board down.

Or they're up on the other 2 who have launched..

That’s what I love about a whole new AC class!  We have no idea!  
 

(I honestly never thought I’d see that comment from you!)

Or steering an old cutter in the marina.

Carbon often looks rough in photos but damn it’s a little too hard to see the size and shape of the flaps. There’s no discernable flap joint in any photos that I’ve seen, unlike the photos when TNZ and AM launched.

If they really do have 80% of the foil wing weight in those torpedoes then it’s possible the rest of the foils are fake.. Max S does seem a little obsessed about not revealing things.

Flap?

Flap?

I think so.

Sure, let's say that.

Interesting that ETNZ is a foil outlier already, Hoggie. It will be interesting to see how they converge over time...or not.

Still got the fracker to splash but, yes, flipper’s flippers are on their own path.  

Hull shape appears to this non-sailor to be a factor as well.  The boats can’t be towed on to their foils when the racing starts and I think one boat trying to get another boat off it’s foils during the pre-start is a viable tactic, as of now, if one hull design shows to not be stable in displacement mode.

You have to admire their attention to detail. They even color matched  their flying lines as they cross over the red Prada stripe.

I missed this Jimmy driving the forklift thing... did that happen? (I am well aware that it didnt crash into the boat)

So what do we think happened here?  Did Jimmy drive the forklift into the side?

Edit: Shit, sorry, wrong colored lines.

Thats where they hid the Herbie unit, but the matte finish gives it away. They should have gone with chrome paint again, can't even look at it.

I know they said they were more focused on hydro, but to me their hull shape and appendages look more like airplanes and wings and AM's look more like sharks and fins.

Hahaha..I actually love the AM hull which imo reflects a significant contribution by their Airbus partners. It's interesting that the Defender and CoR who co-wrote the Class Rule have gone in one direction, and AM a different one, which may well be an interpretative difference. But I imagine Dan Bernasconi and his team would have started crunching their numbers once they saw AM's shape - they'd be crazy not to, in case they missed something...

What are the white marks on them that look like Sharks teeth, just decoration or are they sensors? Wild.

It must very tempting to glues some random shit on the foils and paint some teeth on it knowing full well the other teams will pore over the photos going "what the fuck is that?!"

Until, perhaps, the measurement committee decide that removing said random shit constitutes a new foil

Ehmans' 'Breaking news'?

I thought it looked like a patch watching the stream, then convinced myself it must be just a mast reflection.

But if its there from other angles it can't be a reflection.

 

[See Level]

How's the boat going to react if/when they crash down at high speed?

That keelson? shape looks like it could hook up pretty good at a bit of an angle.

Hmmm. I don't think there will be a lot of downspeed action in the start box - apart from the old hook, maybe. Displacement mode would be fully fatal against a foiling opponent. Much like the AC50 action I'm picking. Unless these boats can launch onto their foils with relative ease (and we've not seen any indication of that at this stage).

Jimmys contribution to the design ^_^

*scene, interior, meeting room: design meeting somewhere in Italy mid-2018*

Head Designer: (who is their design team?) OK so a wrapping things up we're a go for this a design? I send thisa file to the builders and we go for pasta!

Jimmy: *ahem*

HD: Jimmy, you have a something to say? We already told you no crass cammo-wheel & no hiking like lasta time.

Jimmy: fuckin' sharkteeth.

HD: ...

Jimmy: ...

HD: Um whata you meaning there Jimmy?

Jimmy: fuckin' sharkteeth mate!

HD: what??

Jimmy: Mate.

HD: ...

Jimmy: Maaaate, we need to paint fuckin' sharkteeth on the mini-bullets on the foils!

HD: ...

Jimmy: FAAAARKIN SHARK TEEETH. On the mini-bullets. On the foils.

Jimmy: Shark teeth!

HD: *eyes glaze over, shakes head*  NO Jimmy, just no. OKayea so we go for pasta now!

*cut to boat-shed interior, night, late September 2019*

Jimmy: *applies last touches of paint then sneaks away* hehehe, maaaaaaaaaate

*scene exterior, Luna Rossa launch day*

Crowd of Prada execs: whata 'da fuk is this sharkteeth nonsense, we'rea Prada for fucksake! And where's the mirror finish?

HD: *grinds teeth* I'ma gonna kill that motha...

Whoa, that rudder is way thinner than the dock line, and it has to hold 75' of boat in the air.

My thoughts are that the flappy bilge keels are doing the greatest amount of directional work rather than the rudder.

What happens if you do? Does Trump call you a bad name?

Besides, it’s way more fashionable to display it upside down these days.
