America's Cup

I'm still looking for the wire on the boat.....

But yup, great to see our wee country leading the world in such a cutting edge competition. .

Not really leading the world. More like first in a 4 horse race.
Totally cool all the same. I am really enjoying the racing even though it doesn't play live here.

I watched most of the racing with KZ7 etc. And then that that cheating .... Dennis turned up with a cat when we wanted to sail the j class yacht , what a crock.
.

Na mate, TNZ got what it deserved there. That wanker Michael Fay and his lawyer boyfriends found a loophole that allowed them to not have to wait for 4 years for the next challenge. There was no time or interest from other teams for a LVC. So the yanks said fuck ya and showed up with the cat. The rest is history.
Looking forward to a TNZ win.

Not quite. I don't actually know the bloke, but what his team did was simply read the rules and realise that the American format wasn't actually the way it was originally intended. From there I'd have done exactly the same, challenge the holders as I was allowed, with the boat rules that gave me the advantage rather than have the class dictated by the holders.

The very first cup race was characterised by bitter controversy off the water, it’s always been a very rich man's game and a lot of very rich men tend to run roughshod over ethical considerations that stand between them and success. Which, let's face it, is ugly and there's more than a hint of that ethos in the current holder's camp.

The actual sailing is a bit of a by-product, we rarely see equally matched teams sailing for the prize, but we do see occasional flashes of technical brilliance, and for me that's the buzz, there’s few sports that depend quite as much on, (or even allow) sheer engineering excellence.

You might have a point. He rides a Ducati. Thing is, he's made it reliable.

which is more than I did with mine. Good luck to him.

Ignoring friction and a shitload of other factors... if the boat's going exactly downwind it doesn't work, but if they bear away to say 45 deg then the windspeed over the sails is much higher. High enough to increase speed by more than the increased distance. It means the wind on your boat moves forward, which means you bear away more, which means more speed.......

In the case of those cats the speed difference is enough to mean foiling... or not. Which makes the difference huge, they can get to the leeward mark in almost half the time by travelling 1 1/2 times the distance.

So its a wing , the shape of which changes the speed over the leading edge and top surface so that the "wind" you move into would be the vortex shed by the foil , ie the wing accelerates the wind speed

Have I got that right?

Im still with the cabin boy and first mate bates , or Master as we know him

Thanks for that

Yeah, but that effect isn't what changes the apparent wind angle onboard. As I said going directly downwind and with the sail extracting 100% of the wind energy and the boat being completely without drag then your maximum speed = windspeed.

Bear away to 45 degrees with the same assumptions and the boatspeed = windspeed + tangent of that angle, about 1 1/2 times windspeed. And what's more the wind as felt on board is both faster and coming from further forward, purely because of the boat's speed, and that makes a rigid wing rig, (in particular) more efficient. Some would say the boat is making it's own wind, and it's an effect that becomes self-propagating, sort of feeds off itself, until you hit the peak of that velocity/angle curve, and that peak on a high performance multi can result in boatspeeds more than twice windspeed.

That'll teach them to call our boat a tractor!

[MisterD]

That'll teach them to call our boat a tractor!

Probably the wrong choice of insult, given the where Ed Hillary managed to get to with slightly modified Fergies...

[yod]

That'll teach them to call our boat a tractor!

if ours is a tractor, theirs is a brick!!

Apparently there is a super yacht parked beside oracle's super yacht who is flying a kiwi flag.
its owned by an American billionaire.
It seems that Sir Russell C. passed a message through a friend for him to take it down.
I hear he is looking for a bigger flag.
priceless.
He says he doesn't back cheaters. hoo ra

here is a link to it

As well as watching on TV, I've been looking at the America's Cup website Virtual Eye function in real time on the iPad. That's an amazing utility which gives a birds eye view showing speed, separation and so on. Watching the upwind leg is a real revelation. You can also speed up the replay of a race on Virtual Eye and that REALLY shows where the gains and losses are made!

One thing that really worries me....
They have 2 boats and we have one.

Imagine our difficulty if there is a collision and the boats are significantly damaged.

Answer is they roll out their number 2 boat and say ok lets go racing.

I'm sure its a consideration.

Yep I've eluded to that very tactic too. I hope they dont but.............

[leathel]

I will have to record Sundays races as I will be out riding ... loving the racing

Been a couple of close shaves recently too.
