I was referring to Steve Hayles who was shown the door. And Scally posted the video of the episode, so, anyone who saw it had the right to be offended, and were. Off thread, anyway, sorry, so I'm done.
The thing that pissed me off the most about that whole situation is that the people who brought the Rule 69 protest never once had the decency to ask Annamieke her opinion. She was horrified by the protest. Steve Hayles was not shown the door, he chose to leave for various reasons.

Yacht.de asked Boris Hermann about the foil problem this morning and he said that it is not serious.

In the article he says:
Wir haben festgestellt, dass wir einen kleinen Schaden am Steuerbordprofil haben, was nicht ideal ist. Wir müssen also viel vorsichtiger damit umgehen und hoffen, dass es nicht noch schlimmer wird, denn es gibt im Grunde keine Möglichkeit, es zu reparieren.”

Translation by google translate.
We found that we have a small damage on the starboard profile which is not ideal. So we have to be a lot more careful with it and hope it doesn't get any worse because there's basically no way to fix it."

So it is a serious problem: they miss boatspeed. (Essential in an Imoca race)

Weather routing Feb 2nd

The big picture is in pic 1 with Brazilian navy synoptic overlay (00 UTC), edited. Boat positions 07:40 UTC. GFS pressure 00 UTC. The HP zones marked “A” and the LP zones marked “B”. The St Helena HP is still above Tristan da Cunha blocking the shortest route to Capetown. The cold front at the Brazilian coast is present, as usual. Boats have to go in between.

Pic 2 has GFS wind for 00 UTC in order to cross check with the Brazilian navy synoptic chart. The wind barb drawn on the chart (see red box) is quit different from the forecast for wind speed and direction.

Pic 3 has GFS wind chart @ 00 UTC.

Pic 4 has ECMWF wind chart @ 00 UTC.

Both forecasts seem to match for 00 UTC.

As I noted that Guyot seems not to be able to maintain boat speed with the other boats, although the forecast predicted a bit more wind and pressure for them, I back tested the IMOCA @103% polars and IMOCA 2015 generation polars against their position yesterday.

The IMOCA 2015 polars seem the most accurate. Although these underestimate Guyot’s boat speed with a max speed of 19 kts in the polars. Guyot does sometimes a lot better. Will tweak further and route with IMOCA @103 % and the IMOCA 2015 polars. See pics 5 to 8.

Pic 9 has the weather routing. The flyer south is for the 110% polars. The routing cutting the corner closer to Gough Island is for Guyot @ IMOCA 2015 polars.

Pic 10 has the Wx table. Notice that the ETA has come forward to Feb 12th. For all boats. A very close finish predicted atm. A very large chunk of the routing in the Southern Atlantic is now powered up to an enormous LP zone with a projected hPa of 950 (a very low-low), compared to yesterday. The routing is also more to the south now in order to maximize that ride east with the beast. See pic 11 for the Wed 8th 1200 UTC projection in my next post (only 10 pics per post on SA).

They bloody love him. He is Christ reborn to resurrect German offshore sailing. Good for us, we get more (biased) coverage.
Yes that is true! Especially now that he is on land they can get a hold of him more easily. In the article it also says, that they inquired further about the foil issue but he only provided that short statement for now, maybe he tells more later today but it seems to be a non issue.

That is what Will Harris said in the video they uploaded. Then they asked Boris about it (which is what the article is about) and he said "there is no real problem" so I don't think they are slowed down by it, at least not anymore, maybe they were a bit initially as they discovered it, being more cautious.

The entirety of the field predicted to finish within 1.5 hours, can we please stop pretending any team is better or worse right now? This is such an incredibly close race that everything is still open

1.5 hours for the whole field... Half the time between 1st and 2nd in the first leg for the full 5 boats... For a leg taking twice as long

As predicted yacht.de has gotten a hold of Will Harris to ask him about the damage

The main points:
  • Will has found a thin tear in the foil during a routine inspection
  • Because of this they had a closer look and found some other small damages
  • One damage is small delamination at the rear edge close to the bearing
  • This is the same spot they reinforced before the start, so probably too little reinforcing
  • They are checking the foil every 2 hours but believe it will not worsen if they don't adjust the foil. Until now the cracks have not widened
  • They expect only little impact on speed, at maximum 5%
  • If the damage increases they will retract the foil to make sure it stays repairable in Cape Town as they don't have a replacement
He also said some general stuff about the race:
  • They are optimistic since the boats are all really close and the conditions for the rest of the leg should favour Malizia (stronger and downwind)
  • The boat was an oven in the Doldrums
  • They will go south of the SH-High, there are multiple possible routs right now, as south as 45°
  • They have started rationing the food and are running out of toilet paper

The German „Yacht“ posted and interview with Stanjek about his learning curve on an Open60 and skippering Guyot for the second leg.
Thanks. One of the most informative of the recent publications, esp. tech-wise. I also checked the auto-translated English subtitles; they are alright to get the gist of what he's saying.

edit for the video-link:

Is it just me, or is the tracker no longer showing 4hr, 12hr and 24hr average course, speed and VMC? Used to show up by hovering over a boat. Now nothing.
Mine is showing current, 4hr and 24hour speed VMC and distance. It shows less on the phone version than on the PC version.Bothe versions still have a pop-up when hovering.
