Race 13 ....... on Friday .......?

 

[tavis]

Awesome! Thanks for the linky.

Most models show 10 - 14 kts. But..... yaknow.

 

[richiec]

Thanks. These embedded yt videos on sailing anarchy have the only way I've been able to watch. So cheers dude.

At this Point the Wind Speed isn't all that important. It's the TIDE. Anyone knows if we have a EBB or FLOOD Tide today?.

Care to explain more?

We have a 'Ebb' tide till Sunday (NZ Time) I believe..... switches to Flood then.

11:49 Sat Max Flood 3.5 kts

13:23 Sat High 6.1 ft

14:41 Sat Slack

17:48 Sat Max Ebb 2.3 kts

Agree that the models show moderate winds, but SailFlows wind buoys in SF bay already show 7-10 knots averages with 14 kts gusts. If the wind builds as it usually does this could indicate winds in the upper range once again. But at least there isn't a strong ebb reducing the limit.

That is for Saturday. We're going to have Racing scheduled today if I remember correctly.

Oops, my bad. Here's today's:

11:08 Fri Max Flood 3.8 kts

12:49 Fri High. 6.1 ft

14:03 Fri Slack

17:08 Fri Max Ebb 2.4 kts

Love to see OTUSA win a couple more, but sure looks like the cup is going down under. Hopefully the Kiwis will pick a smaller, more affordable boat for the next cycle and we will see many more challengers.

Lighter today. Supposedly!

So, max Flood at 11.08 PST...bad for New Zealand cuz once it gets closer to Race Time the FLOOD disappears and it gets more even and (or) a slight EBB.

There have been 5 Races contested in an EBB Tide this Regatta. OTUSA 3 ETNZ 2.

But its getting better everyday for NZL no?

Can someone explain why tnz do not initiate a fybing duel when they find themselves behind on leg 2? Surely they could hope for a bad OR gybe or at least a split?

dragon

these are the best of the best

i don't think your plea to internet nobodies means zac shyte

I was also suprised that they didn't split more when they were behind yesterday??

The boat ahead is in control in these races because the wind is always forward and the boat behind has no shadow.

Posted on another thread, but probably better here:

Doing some analysis using Cupinfo statistics: http://www.cupinfo.com/cupstats/

For Race 12

-- Ground wind averaged about 16 kts ... don't remember exactly what the current correction was, but I think it was about 2 kts so that means 18 knots corrected true wind speed....fairly high, but not quite right at the wind limit.

-- Oracle sailed generally upwind between 50 and 55 TWA (http://www.cupinfo.c...nd-angle-01.php) which according to their polar for the day (http://www.cupinfo.c...ar-plots-02.php) would mean speeds of about 27 kts average for a VMG of 16.2 kts. TNZ sailed upwind mostly at about 45 deg at 25 kts for a VMG of 17.6. Yes at times Oracle was sailing upwind at 30+, but based on the cupinfo data, they had to head off to about 75 degrees to do so and their VMG went to shit....also, according to the TWA frequency data, they didn't actually do this all that often.

-- Cupinfo has not updated tacking speeds for races 11 or 12 yet....bottom speed is not the critical number, though it is indicative to some degree. Obviously the best measure would be VMG loss through a tack vs. straight line, but no-one seems to be crunching those numbers and I don't have time to go through the raw data. Oracle have certainly improved and certainly have a higher bottom speed through the tack, but it looks to me like they do this partially by sailing lower into and out of the tack which would hurt your VMG a bit.

-- NZL gained 2 seconds upwind while largely being controlled by Oracle. I didn't see many cases where Oracle couldn't sail where they wanted to in that race. I think NZL did a good job tactically considering they were under Oracle's thumb, but they did have to make 2 more tacks then they would have if Oracle wasn't there, and at the top of the course had to sail over to the unfavored side. Overall I think NZL had a slight upwind speed advantage in these conditions, but nowhere near what they had 5 races ago.

--NZL sailed a lot of extra distance on the 4th leg due to the wind shift when they were on the left side of the course (forced that way by Oracle). This is where the lead went from 10ish seconds to 30ish.

I predict we come out and smash them in the first race
