In general, the boat that wins a W/L race will have the better average VMG

At times the boats sail hotter angles and go a bit faster, and at other times they sail higher/deeper, and go a bit slower. Also, the target TWA will vary depending on TWS, so if boats are in different wind speeds, they will be sailing different TWA's

if you want to look at the stats, they are available for each race. This is the data transmitted by each boat, and VMG is wrt the wind measured on that boat - so when you compare VMG's between the boats be aware that they may be sailing in different wind speeds.

here is the link to the data - just choose a race and the quantity which you wish to plot

Thanks, I did do a yacht race once, and that explains a few things.

So lots of BS from Jimmy then

NZ Herald

You win 4-0 against a lame duck competitor who has systems issues, and then claim that you are going faster (which they weren't).

Pretty sure they were going faster than they had been in similar conditions before. They had over a week in the shed between the last RR and the start of the Semis, to have expected them to not get faster in that time is naive.
INEOS vs Prada is going to be absolutely fantastic racing. I think I'm going to have to deal with the lack of sleep to watch it live this time.

I'm not convinced that the boat is going any faster. They are sailing it better, but then it's easy to sail a boat well when there's no pressure on you from your competitor. They do seem to improving their VMG though, especially upwind.

I agree that the next round will be compulsive viewing. It's going to be tight, and Ben's going to get angry (probably)

Pretty hard to argue that improving VMG is not going faster!

Haven't had the time to dig into it in any great detail. From watching the racing it really did look like LR had a new high mode that seemed very fast.
I think conditions on the first day were very different from what we have seen in the RR - winds stronger and steadier and not much in the way of waves. Yes LR looked very impressive - very clean - not sure they had more boat speed other than that

I can't help thinking that different foil designs probably work much better in different wind conditions. There is a bit too much luck in that for my taste

If you haven't been watching Mozzy Sails videos, the analysis here is excellent.

Indeed. I do wonder whether the stronger winds in day 1 had something to do with it though, as it would in itself pull the apparent further aft, and might have allowed them to feather the rig a bit more. Difficult to know, but they did seem to have a good high mode going on upwind.

I've not gone back to check more closely but while watching the whole race, I said the following. "There's definitely some movement between the US foil and hull, but little or none on Luna Rossa". "The Luna Rossa mainsail seems fixed in one position but the US sail seems to be continually moving". "Every time I look down at the speeds the US boat is faster but they have not won a leg yet" (on the second day, I think they won one leg towards the end of the second race). I sincerely hope that Big Ben and the boys are as cool as Luna Rossa in the final. There must be questions about the management that puts a tactician in a position that requires him to 'get his head down'. By having two helmsmen Luna Rossa gives them the chance to take a breath and lower their heartrate a fraction before taking over. All of the above, and knowing the US were struggling following their damage, probably contributed to the cool, calm and successful two days that Luna Rossa experienced.

I think both Ben and Giles have both had training and experience keep cool and focused, and for longer periods than the races take.
Remember Ben's first comment after the 4th win- " Calm down lads"

Yes, I think you are correct. The point I was trying to make was that the management of the boat, in the case of Luna Rossa, seems to encourage a calm attitude. The US boat seemed more muddled. Just before their big crash someone said something like 'that's a difficult manoeuvre', if that person was responsible for calling the move he should have said no. If not he should get on with his work. Again the management let them down.
When GB and Italy get out on the water, if they are both at their best, it should be fascinating and close racing. I'm interested to see if the faster boat wins. GB and US were both the fastest boat when they were last in a series.

Just watching some video footage of Ben out yesterday and ETNZ out today, and one thing I've noticed is that Ineos seems to run with the bow well down when at full chat, whereas ETNZ seem to be keeping the boat much flatter.

interesting little video on angles of attack:

Yes, just going to watch that now.

What the change in sailing angle suggests to me is that they've found more lift in the foil to the point where they can level-off the foil more at high speed. If that is the case, then that would help reduce the speed at which they can foil and also increase their ultimate top speed without the foil cavitating.

The next race will be interesting.
