None of the boats that were actually built were ever optimized for lifting rudders. That would be a pretty dumb move to build a boat around a feature you know you can't have.
What we meant is they did the study and used it as a starting point before adapting it to a configuration without lifting rudders. The results of that study undeniably influenced the designs and they took it as a starting point for some of the boats but of course they totally reworked it, in part to account for non-lifting rudders.
For instance, I'm quite sure today's boats have a lot more rocker and the bows are wider/flatter than what was studied for the "Super 60".

of course, boat design evolves.. nothing new or special about that.

we are effectively on to 3rd/4th generation imoca foilers now.. so of course they are different.

sorry, i read your 'current' as 'latest'. I apologise. In a general sense you a right, Linked-Out / Biotherm have lifting rudder in their design DNA.

However, the Volvo Super 60 design brief required it to be a one-design Volvo-specific boat (possibly with lifting rudders etc), but it also had to be a competitive IMOCA (reliable, safe and up near the front, but not necessarily winning). This was directed from Volvo so teams could do both races and widen the appeal, create a market for the boats etc etc. So I'm not even sure you can say Linked-out is optimised for lifting rudders.. its results would say it was well optimised without them..

PRB and 11th Hour were both done well after the Volvo Super 60 was scrapped. This is even true for Apivia, a custom shape away from the VS60.

The key point is not lifting rudders or not but T rudders or not, they all have "lifting rudders" currently, pivoting ones, but of course this wouldn't work with foils on them.
PS : Your sister ones might do as well :)

The whole "Live from the Southern Ocean" media package is a game changer - with TM team at center stage and Rosie as the star no doubt. I wonder if we will look back at this as the investment that propels the Ocean Race forward.

I tend to think so too, and in english it's spelled "$ailing." If I was a sponsor I'd put my money on teams like Malizia, who are both genuine and sophisticated in their web and social media approach, with exactly the right crew to pull it off. I'm already looking at Devold sweaters from Norway, for example, and I bet I'm not the only one. Why, I'd even get on Tik Tok if the boats were publishing there.😀

Malizia looking really smoking good in these conditions for the first 50-75 Miles up north.
They may have to do some gybes now to avoid the land in front of them.

I'm no navigator but they seem be on a pretty good line to head right through the Le Maire Straight. According to Wikipedia, "The stormy weather and strong currents that the waters around Cape Horn are so famous for also affect the strait. To avoid the risk of being blown against the shore of Tierra del Fuego, sailing ships often instead favour going around to the east of Isla de los Estados." Doesn't look like the teams will be taking the safe route.

On a side note, learning about obscure islands, straights and other interesting geographic locales is one of the many things I enjoy about following this race.

Definately close for TM in the strait.
TWA at ~100 degrees according to Grafana. Will need to head up +5 :)

Difficult Situation for Holcim-PRB. Malizia continueously is sailing into more and more wind.

I think they are close enough to benefit from the same pick up in wind. The latest tracker update is misleading because Holcim's position is 10 min outdated (making 4sm at the current speed). This is a reoccurring issue for Holcim. With the next update they will have made up some of the current artificial loss again.

obviously. Lifting rudder is also a common term for winged rudders giving vertical lift..

anyway.. moving on!

Really ? If I put "lifting rudder" in gg or bing image, I mostly (like 99,9 %) see either pivoting or vertically lifting (typically on Farrier tris for instance) rudders without foils.
But indeed, let's move on .. ;)

The Tracker has gone completely bonkers, lol:ROFLMAO:

lol, it's like it can compute either no boat having passed the Horn, or all of them having passed it, and not caring about land to measure the distance to Itajai :)
By the way, the 3D (globe) view that existed on geovoile trackers before is really missing on this leg
