If you watch the recently posted video on TOR site by HPRB (Content from the Boats) you will see what happened: there was an unintentional gybe similar to the one they experienced I believe it was yesterday (time zones are throwing me off right now), water and sails in bags pouring through the hatch, and it looks like they broke some battens (picture of the crew on deck sawing through them towards the end) and Kevin commenting the wind was 50 knots (49.something on the screen). I thought I heard Abby faintly say to the camera "so close..." They have for the past several hours been sailing at a slightly faster speed than TM.

Here is the video


Also on Malizia Will Harris is talking about a damaged fractional downwind sail. They are left with the J2 for the remainder of the race, IIRC.



Go, TM!

If Holcim's inadvertent gybe, like the previous one (kudos to them for showing video of it), resulted from burying the bow, then TM's bow design will indeed have won this leg for them, fingers crossed. And given how well they competed in the light and/or upwind conditions recently, and with a full sail inventory after Itajai, barring a bizarre navigation decision like the one approaching Cape Town, they ought to lead all legs from here on.

The question is, why would you design a boat that buries the bow just when you need more power?

They show TWA, TWD, TWS, AWA and SOG in the dashboard.

Would AWS be pretty easy to calculate from those?
If there is unknown current (speed and direction) and leeway angle is unknown too, then the answer is no. But TWA, TWS and AWA already give you AWS if there is no leeway and no current. TWD is not useful at all, and SOG is only relevant for the case current and leeway are to be accounted for, and is not enough if both factors are fully unknown.

Weather routing April 1st
First backtesting boat positions against the wx projections from yesterday shows all boats stay behind projections. As the sea state detoriated, that can be expected. So I powered-down all a bit. TM @ 95% and HPRB @ 90% as these rough conditions are better suited for Malizia.

Pic 3 has Sat IR color 07Z and synoptic situation. You can clearly see the LP and attached cold front stretching back to the coast. A HP is below Buenos Aires. Boats 0640Z.

ASCAT got lucky this morning, see Pic 4 ASCAT 0339Z.

Pic 5 ASCAT 0339Z and GFS (02Z run) wind and pressure zoom 1. Stuff seems to match.

Pic 6 ASCAT 0339Z and GFS wind and pressure zoom 2. Wind direction is off.

Pic 7 ASCAT 0339Z and ECMWF (02Z run) wind and pressure zoom 1. Actual wind for TM is 5 kts higher, wind dir +/- 10% degrees off.

Pic 8 ASCAT 0339Z and ECMWF wind and pressure zoom 2. Both wind dir and speed are off.

So the wind models more or less agree on today. Wind in the 25-30 kts range for TM and HPRB. Sea state atm +/- 4 meters significant waves according to WAM and WW3 for TM and HPRB. As the first two boats are in the top left quadrant of the LP, they enjoy following seas though. Sig waves 4-5 meters projected to Itajai.

Pic 9 Wx routing and table. GFS blue-ish. ECMWF red-ish colors. Only for Biotherm the models don't agree.

Also TM are down to 2 downwind sails, so 100% polars over all windspeeds are not an option anymore

I'm just listening to the latest episode of the "End of the watch with Team Malizia" podcast.

Not sure anyone noted it here but Rosie apparently had a concussion. When the crew treated her she passed out several times.

This was new to me, from the videos I got the impression she banged her head but it wasn't a concussion.

They did say she was concussed right away. That's why she is now on bed duty, Antoine is on Rosie duty and this whole thread is worried everytime Malizia is bouncing in waves

You missed some important content then.

She was clearly acting concussed in video following. If you have experience in the injury it is obvious.
