yeah, get help.
It seems more likely that the Catalonian government/council, whatever it is, is just trying to spread the AC love and AC wealth around the region.

Going to be a busy month for the Teams in September:
September 9-10: France Sail Grand Prix Event, Saint-Tropez
September 14-17: America's Cup World Series Event (AC40)
September 23-24: Italy Sail Grand Prix Event, Taranto
I am sure that there were some conversation between ACE/ETNZ and CoR/INEOS about these Events kind of all in very close proximity.

Your comment is nonsense.

Love & wealth? The Spanish/Catalonian Economy is on the brink of complete collapse!!!
Converting a wingmast cat to a mast/sail type cat would be tricky because the loads are in different places.
Cats can be built to handle a mast and sails though.
The main difference would be the load on the back beam because the mainsheet is pulling the headstay tight. The AC cats have the dolphin striker running fore and aft which could possibly help support the back beam, but would that system work if the headstay had huge loads?. They would still need to structurally design the boat differently to use a mast/sail rigs even if it did though.

They can't achieve the loads or stiffness you can get on a mono because the the mast is stepped on air. A twin skin main is therefore unlikely on the F50. If the wings get deemed unmanageable - which is a possibility, they'll go to a new platform, most likely a mono.

Will be interesting to see whether SailGP will impact AC commitments. AC teams may well pull their team members from SailGP to have them in camp the same way international rugby teams like the AB's pull their players out of Super rugby for to have them in ABs camp building up to the world cup.

The wings could be managed with three tethers attached to motorised trolleys with live bollards and each tether operator being able to communicate with the crane driver.
I can see them changing how they handle the wings - especially in a breeze. Sydney was an expensive lesson.

Barcelona and Catalonia are certainly making the most of their favourite and expensive position. Very impressive.

Gettin back to the Auto Pilot. You are exactly correct in that it only controls ride height, roll and pitch. it doesn't sail the boat.
Barry posted this video in the Sail Gp thread.
At the 5:04 mark he says:
The autopilot JUST relies on the gyrocompass! It controls the ride height, pitch and roll to give it a stable platform! The sailors do all of the rest.
So, it just like I said before. The AC40 autopilot is a gyro controlled system that tries to hold the "platform" in place.

having some trouble getting my head around how the AP can control roll . i don't believe it can without controlling sheet or heading which i don't believe it does
altho maby it does ?
Is it just talking about foil arm cant?
breezie
Member
dont think so that would not really give control of roll anyway
It would have an affect wouldn't it, through changing the force distribution of the foil and the arm relative to the hull, you'd change the angle of the hull relative to the water, and thus the rig etc? Or is my naive understanding too naive? 😂

oh yes it would affect roll but in terms of the balance between righting moment and sail ...not going to give authoritative control. in my experience (dinghies) the roll of the boat is controlled by some combination of sheet and heading changes...... in AC sail twist is also used
