Vendée Globe 2016-2017

I notice that Armel is now on a similar heading to Alex (034), the next update is at 0400 and judging by windytv's representation of the wind I would not expect any material change in respective positions at that time. Interesting looking at the 4th and 5th positions who are nearing the Horn and how that is developing. Looks like Paul Meilhat in SMA has made it to Tahiti.
 
He's played an absolute blinder. If the tracker is correct in 9-12 hours from now Armel will run into very light headwinds and Alex should have light winds but he'll be on starboard and have them on his beam. It's game on!!!
My money is on a new leader tomorrow.

Alex is taking The Boss well east of the Rhumb line, so although he is now going significantly faster, he is not gaining miles at the same rate

Don't forget though that the finish is further east than they are both at present, so relatively he is doing good.. I think he is playing a blinder strategically at the moment. Lets keep our fingers crossed. Still many miles to go ...........

Neal McDonald (of fabulous Volvo fame), on Vendee TV, reckoned that HB could still be the faster design downwind. But Armel better in light airs or beating. That may explain why Armel appears to be taking a slightly more westerly heading through these light airs, with a beat on the other side and closer to land.

Contrary to some other posts, I dont believe that Alex following Armel is a good strategy. In the two high pressure zones, it is mostly first in first out. If Alex takes the safe, 'follow Amel' option, then he is (almost) guaranteed only 2nd place. But taking a gamble on a different option will still see him in 2nd anyway if it doesnt pay off, and with a chance of the win if it does.
Alex seems to be shaping up to head through this high pressure, low wind area, more to the East than Armel, and riding his current wind a little further than Armel managed.

And we also know they are also choosing their route through based on the favorable currents from satellite data.

Methinks this is where Alex will be looking very very closely at the data, and for alternate options.

I still think he should have gone East last night.
But I am the Amateur, Alex is the Pro.
And what a Pro!!!
Go Alex. Go Pro!!
 
It is real nail biting stuff, not just at the lead but also at 4,5 & 6 who are in the variable scheme of things within spitting distance. I also see Stéphane Le Diraison has finally moored up in the port of Melbourne after a long haul under jury rig, while Enda O'Coineen is now at anchor at Stewart Island south of New Zealand to effect repairs.

Alex is not going to make much progress at all in the next 12 hours - he would be better off having a big cook off and then getting his skull down. Meanwhile Armel is flying again.
 
It is interesting to view the latest 1700GMT plot from https://gis.ee/vg/ which shows on the forward time projections changes to the tracks of the contenders including deffinate tacks. How are they making these assumptions? Are they just guessing?

Yeah - I picked up on that too - I put it down to a glitch. It first started doing it with the prior update at 1400/1500

Forss, I checked your tracker https://gis.ee/vg/?boat=3
and find something wrong at 11:00 GMT report on BP5 info, COG=326, TWD=10, therefore TWS should be (360-326+10=44), but instead it is TWA=+136 (326-10-180=136)
Armel is definitely beating to windward (TWA=44), not going downwind (TWA=136) at that time on your tracker. I don't know if it's about wrong raw data or a glitch on your tracker, but wrong math formula is used.

Funny to find HB has TWA = -4 degrees, but that's certainly due to wind data not coming from a boat, but from a not quite correct weather prediction.

Thanks for info! I haven't noticed this bug before. My math problems :P
Will fix it tomorrow.

Also new routing/prediction feature is available. Works like old one with hour buttons or slider.

Small bugs are there but should be working most of the time.
Every boat has different polar % and some number look wrong for me, but will fine tune later.

Thanks Remora Sailing for great API!

Works! So nice to be able to contrast actual courses with previous projections. Thanks to so many, especially you, Remora, and Windytv

Suggested route for Alex very strange, and probably absurd.

I have asked the clever chap that has synthisised this data what the point of the Remora projection is. Honest question from my perspective. Key point is we can access the original projection as described above.

Hopefully, Remora is incorrect for AT but he should be able to turn due North in 8 hours and start making good.
