Is it just me, or the bottom of the boat seems far from being smooth? It looks sort of unfinished.
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.The work on the Italian bulbs seems much cleaner than that of Defiant's which looked rather rough. May be the Italians have greater skill here? Hard to see any sign of a movable flap on their foils. Are they permitted to rotate the entire wing?
Is the boat tipping towards the camera, or is that just an optical illusion?
AM are the outlier in terms of things that matter. They're starting to look like they've missed a trick with their hull design.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.
they can only make 6 foils!What difference does it make what the foils look like now? These are just testing foils and the foils that matter won't be advertised, right?
Or they plan on it being out of the water more than the other teams. They could be the ones that figured out the trick.AM are the outlier in terms of things that matter. They're starting to look like they've missed a trick with their hull design.
Which makes it interesting that LR launched with 2 identical foils, apparently and assuming they are real.they can only make 6 foils!
They touched the water, they count towards the six. It would be incredibly stupid to waste 2 foils.Which makes it interesting that LR launched with 2 identical foils, apparently and assuming they are real.

Very short chord length at the bottom of the rudder?From Farevela's fb page

Not sure that they are the same. Fences on starboard only?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
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?
Cleanest sprit, aero drag is pretty slick, transom most tapered (?) plus round all the way back. Chines on NZ not aerodynamic, deck plate on AM looks clumsy, but their cockpits have a nice chamfer at deck height.
Agreed, also wondering if the anhedral/dihedral foils plus the skeg/keel is designed for takeoff drag minimization. The hull provides leeway resistance with minimal foil arm in the water, but the lifting part of the foil still provides good lift at high foil arm cant angles because of its angles.The way I read his comment in italian is that it is about minimizing drag at takeoff, but not sure.
Most beautiful boat to date.Very short chord length at the bottom of the rudder?

Really? So the US requires the flag to be reversed on the starboard side... how backward. </pun>Italy doesn’t share the US requirement that a painted flag faces the bow
