Agreed!

For the non  French speakers, I do not know if you get English sub-titles on the video above. So a few nuggets:

Adding the cloth on the back of the aft beam to make a better shape added 1.3 to 1.5 knots of boat speed.

They gained 15% on the aero drag between 2017 and 2020...

They change the shape and angle of attack of the aero fairing of the front beam; they added some structure and film below the boom to close the gap between the main sail and the roof/deck. They extended the roof aft to improve air flow over the main saill all the way to the leech.

And many other details.

The comparison with the flogging sail bags on Sodebo in the previous video is puzzling... Is Sodebo so far behind in the refinements of the boat???

Lots of good aero optimisation gone on there.

I realise it's pretty fresh conditions in that Sodebo video but having that side access door by the helm open appears to turn the covered cockpit into a shower stall...

Compare that to the Gitana cockpit and I know which one I'd rather thrash around the world in...

Also it's interesting to here Gitana talk about minute gains from aero optimisation and then see the stack-pack on Sodebo flogging around
It also has to do with Sodebo cockpit being in front of the mast, but I guess they have some ways (textile based or something) to at least partially close these openings

They do ! On many videos you can see that they are using a combination of a sliding hatch and panels fixed on hinges which can be folded inside the cockpit when someone is at the helm.

They can actually completely close the cockpit from the outside environnement unlike Gitana 17, even though they have improve their cockpit with the roof extension they've added. Fermeture cockpit Sodebo Ultim 3 2.png Fermeture cockpit Sodebo Ultim 3 3.png

Keep in mind the boom on Sodebo is a lot lower and behind the coach roof so the boom and sail bag are not in the air flow. There's a bit of turbulence shaking the bag but it doesn't look like that would cause much drag.

They also had a soft cover closing the gap under the boom from the start. They do have a fairing on the aft beam but it looks a lot smaller and probably not quite as effective, probably more gains to be had there than with boom...

Relatively good news for Sodebo: the damage on their foil and daggerboard (see post # 29 and 30) is repairable in-house. Thomas Coville expect to be ready to start in November and they have decided to extend the start window to mid-January; so basically, they intend to go, no matter what...

It just seems from the outside looking in that the three big programmes are bottomless money pits...... Breaking something like a board or rudder is another ?? days back to port still paying crew wages then the haul out and then there was 5-8 shore crew sorting it out and fixing (if fixable) then back out there and train...... 
I have a fare idea of the dollars and cents in a supermaxi like Commanche but these things with their relentless schedules, I'm sure are more $ than that....... And they do either a full build or re build every few years...... money money money...... I absolutely love them....

From the outside I think they have an advantage of sorts in the way the French teams operate, they run as an company themselves with their own facilities and employees building the boat, maintaining the boat, with their locations in the boat building holy sites of France meaning they can tap into extra locals when needed. I'm not sure anywhere else could compete with that for scale. I guess Wild Oats would be the closest parallel in the monohull world, but they are not building a new boat every few years, did Commanche get her own yard when she was in the states?

I agree that theres some very large pits of money behind the ultimes, although Macif's withdrawal makes the case that perhaps not so bottom less...

Well, at the very least, Rothschild this isn't even a drop in the bucket for them. They estimate the family alone is worth a combined 350 billion, the bank is probably many many trillions. Who knows what the real numbers are but they're basically free to play with other people's money how they wish. This is like a millionaire using hundreds to light cigars. 

And no, Comanche didn't have her own yard like the ultimes pretty much have.

I would guess that the cost of an Ultime campaign is significantly less than Commanche (at least in her early years). 

The biggest portion of any fully pro campaign is the salary bill. Just the number of crew on Commanche was eye watering. 

Also berthing fees in Northern France are as cheap as anywhere else I have found in the world. 

I would estimate that they are spending less than a small VOR budget annually. Brunel and TTTOP would have been in the region of €8-9 million for the year. 

Happy to be proven wrong, if anyone has numbers.
