Yes well done GB team - through 5-2, but as you say light winds are a weakness.
As so often with sailing, weather will affect results.
Not sure it was that simple. They said that they expected the wind to build faster, so were on their slightly smaller main for race 1. When they fitted the bigger main in race 2 they had no issues staying on the foils in what were pretty similar conditions and generally had a slight speed advantage.

Will be interesting to see if LR are hampered at all by their repair. Pressure on them today for sure, to an extent AM will have expected to have been out by now, so in race 1 at least it's just "have a go". If they tie it up, then it gets much more interesting in terms of who the pressure is mostly on.

In the last races of the RR INEOS seemed pretty good in the ligher airs (and in the stronger). The first race yesterday looked like a bad call on the sail choice, but once replaced they did pretty well.

Some suggestion that they have slightly smaller foils that means they have to work harder to keep the boat flying when the conditions are marginal that might explain race 5.

I hope LRPP get repairs done well enough over night - that has been a great series of races with AM and it would be a shame if we can't see it decided fairly on the water.

They definitely do have the smallest foils. Seems a very deliberate choice to optomise for the expected cup conditions. Which is itself an interesting as the average windspeed in October is actually lower. But... That's more due to there being more days of just no wind at all, and when you delve deeper the actual average windspeed on days that would be sailable is more like 15 knots.

Also really hope LR get fixed. The footage of the US fans at their base dancing on the tables after an equipment failure on their opponent rather put me off them.

Perhaps a little unfair - from being 4-0 to 4-3 you can understand that they were happy still to be in the competition. Potentially 2 more races to go so provided LR get fixed the better team should still win.

Worth commenting just how (unexpectedly) close the racing has been. Based on the evidence of the RR LRPP should have been miles ahead but instead we have had some of the closest races of the entire campaign. I think we now have to reevaluate the relative performance of the teams, perhaps LRPP were ahead at the beginning of RR2 but haven't kept up.

Looking forwards to the LV final - very hard to pick a winner at this point.

And as for the AC itself - you have to think the LV winner will be a slight favourite over TNZ simply for experience of the KO stages of LV

So INEOS for the Auld Mug? They have a good chance - certainly our best chance for a very long time.

I think if you go back to the same point in the last cup, where INEOS had won the RR and were awaiting the winner of LR and AM for the challenger final you'll find posts from both of us suggesting that Ineos might actually win the whole thing!

On that basis, I'm reverting to passive negativity and expecting them to get roundly beaten in the challenger final.

You've got a better memory than I have!

I'm enjoying the AC40 / Youth AC racing... but what are they using to power the sail trim/ foils?

Obviously no human input such as the cyclors as per the big boats.

I defer to absolutely everyone in my sail setting abilities, but that never stopped me asking daft questions. Looking at the main on Ineos in the first race today the max draft looked about halfway back, which on my ever so slightly different boat would have me winding on the halyard a touch. Would Ineos have done that on purpose to maybe reduce the power a bit in the conditions? The draft certainly looked further forward in the second race. Or maybe it was an optical illusion because if slightly different camera angles/zooms? And indeed is draft even the right word!?

Flat is fast.

If you pull the draft fowards, you produce more acceleration but the sail stalls out at a lower speed.

Upwind or downwind? Upwind they looked super flat, downwind pretty powerful.

Mind you, I think translating what we do with main trim into these things doing close to 50 knots downwind is not especially relevant.

45-50% aft is about normal for a mainsail with a headsail in front of it. Moving the draft forwards would open the leech reducing both power and pointing ability. That's not going to help you win a race.

True for a yacht, but not true for all. We used to run our Cherub with max draft at 37%, to give mazimum acceleration to get the boat on the plane. It made the boat harder to sail and required a lot more trim adjustment, but was very quick.
