    By that stretch, then France doesn't even need to build up a team to be literally into the winning team. Wait until they drink the Champagne!

    trickle down

    Surely they will be able to break the 24 hours record and go over the 1000 miles mark in a day. I was surprised to discover they date from 2008 (single) and 2009 (crewed) for multis, it feels like there hasn't been much development until now and fully foiling. Is it trickle down from AC or general foiling trend? Difficult to tell but great to have such boats.

    Interesting to see Spithill genuinely enjoying this ride. Is he preparing his next move?

    She caught a Sword fish. It provides a decent pull but not easy to steer.

    Still nice to have a bit of content. Last two cups it felt really long before any interesting picture or video where posted. This one is not the real thing but is the showing the concept on the water instead of an animation. Let's hope they will keep producing (even if I don't expect too much since they will most likely hide the best bits).

    Here is what Are's jury rig looks like during the mandatory test they had to perform.

    Quite logical since the president himself banned cheating.

    Definitely not in its normal sailing configuration. Towing the quant from the bow pull the front of the boat down making it extra draggy and causing a bit of extra wake. Still difficult to estimate speed accurately. Or should I say even more difficult to predict speed as it is sailing in a particular configuration.

    The tracker looks like tadpoles frenzy today. Peche is keeping a good rhythm despite his problem. I hope that its tanks to good balancing rather than a lot of manual steering, otherwise he should get exhausted by now. Quite interesting to see the development of the race and the different choices in the chasing group. When following Vendee Globe, most sailors follow the same routing (or very close) depending on their current position and their routing system (with deep weather knowledge and opponent position). But here after a few day of convergence between Are, Gregor, Susie and Uku; they decided to part again in different groups. Great to have diversity and not a boat procession.

    If it is a constant struggle, it might be a pain to watch but some struggle is not bad at all. It allows for the very best to show their skills and talent, then rise to the top. Yes the America's Cup is a design contest but it's also a sailing one. When sailing dinghies, you also have to balance your boat and have a feel for it to extract the most performance. I really like that this aspect could be kept (in a certain measure) in big scale with AC75's and limit the automation.

    Is it really led by Are. Gregor looks like having the best seat in that fight for 3rd. Will see and as you wrote, the next proper leader board will be established when they pass Cape.

    Start line technology musings ...

    I had the same idea, with projected laser line on the water plus a gyro on top of the mast to stabilize the laser and the camera. The tall mast option is probably the best possible view considering the no drone restriction. Then you could imagine different systems on top of it depending if you want it to be visual for the competitors (projection on water) or the judges (virtual mark on the video feed). Another system would be to have 3 cameras taking pictures of the fleet at the start signal, then have a recognizable object at the front of each boat (like a red and yellow ball) which could then be tracked on all 3 images to provide the position of the front of the boat relative to the start line. That's probably more towards the geek approach. Would not work well with agitated seas but that applies for the above idea as well.

    Peche seems to agree with you and despite his vane issue, he is putting some south in his route. He will be exhausted when he will reach land...

    The 2018 Golden Globe Race

    Gregor might well join them as well. According to your routing he doesn't seem far off the rest of the group. Slats needs a bit more fortune to get back in touch with the leading two. Great to see all boats going well after the hiccups following the start, no serious incident reported for a while. Few equipment lost but nothing race stopping and still a decent fleet with battles in different groups, probably as good as one could expect at the start.

    The 2018 Golden Globe Race

    It would make sense. My initial though was if the tracking system was not crediting Slats of enough progress and suddenly caught up, but your explanation seems more appropriate. Even if the 3 transmitters refer to the same boat, they might have different identification codes which could lure the tracking system into this situation (current tracker last used 1-2 weeks ago when Slats was ~650-700 nm away from now to which his actual displacement is added). I remember some competitors having trackers not working at time (or voluntarily disconnecting them) during a Vendee Globe. But Slats tracking has not been off for 6-7 days! That we would have noticed.

    The 2018 Golden Globe Race

    I appreciate your effort to provide us instructive reports, You really make the race interesting to follow (along with Chay). I would still like to understand how the tracker could provide such numbers and where they are coming from. For a better understanding of the leaderboard and tracker, make my own opinion before coming here and read your report and strategy situation. But I have a hard time understanding where the tracking numbers are coming from, especially for DFT and Distance (24h). It lloks like the distance (24h) is only a delta of DFT at 24h intervall. Then how can the DFT be reduced by more than the distance sailed (+ drift) is where I struggle. Regarding the previous post, this was only meant to highlight the magnitude of the aberration shown by the tracker as it takes a multi in proper wind condition to reach that kind of distance over 24h.

    The 2018 Golden Globe Race

    Wow, Slats is really rowing hard there! Nearly 800 nm on the last 24 hours, close to Gabart record... Does anyone know if the reported position of Slats is correct? Quite difficult to have an idea of the current standing with the fleet spread like this except that Gregor doesn't look like a net 12th. Edit: In case it's not obvious, the question is more about where those 783 nm might be coming from and if the position of his boat is wrong or if there was some miscalculation before.

    The new sailing twin skin setup

    The slot is required for wings because they are rigid and are not suitable for all wind configuration and to add control. As the flaps are required for an airplane to land to increase lift at lower speed without stalling the wing. The slot characteristics would actually have a negative effect if they were able to modify the profile of the wing at will to extract maximum efficiency whatever boat speed and wind condition (this is indeed unrealistic hence the slot). That's where twin skin setup has a slight advantage, the profile shape can be modify when on the water (in theory). Let's be clear, I didn't say it will work, I was just considering the possibility to have structure in between the 2 sails and eventual limitation of this. Then there are plenty of difficulties to get the perfect profile shape on the water with possible changing condition but that's the AC, they might pull something special out of the hat. At least we tend to agree that there should be (significant) improvement over the current twin skins.

    The new sailing twin skin setup

    I don't remember the rules but is there anything to prevent teams from adjusting the shape of the twin skin sail? Like different tension in both sail or inflatable elements in between the 2 sheets? How far could they go (spars in between)? While it won't have the rigidity of a wing, they could probably gain some rigidity and control that way, plus some flexibility in the shape of the sail/wing that they didn't have before (as adjusting the "thickness"). Add the funding and the development that AC will bring and that could be the best thing that this AC will bring to the sailing world. I don't think this will trickle down to everyone's boat but it could allow for high performance racing with easier logistics than wings but similar performances. I definitely wish for a substantial step forward compare to soft sail and close to wing sail performance.

    Percentage of the distance foiling

    If we go back a little, they were not supposed to fly during AC34 (at least it was not the intention of the rule) and they were up the foil for a good portion of the race. AC35 was meant to be flying cats and they achieved 100% foiling time on some races. Hopefully they will hold their promisses this time as well and they will be mainly foiling.

    Larry's AC50 Circus

    Is a team defined by its legal entity or also the people composing it? For instance if the brit enter the F50 circuit under Team Ineos (without UK), have a specific technical team separate from AC but still use the same sailors. I don't see how this would break the rule. It really feels like that rule is more for dissuasion than anything else. On another note since F50 will basically be one design it won't learn AC teams a lot on a platform they know pretty well already. And I don't think any AC team will be tempted by F50 circuit, it risks to divert from the main effort and you file in a team composed from AC sailors, the expectation would be that they crush the competition since they should know how to sail those boats. Anything but wins will hurt their reputation.

    Team NZ

    Isn't it more to avoid turbulence under the wing and make the bottom part of the wing more efficient rather than providing extra sail area?
  23. Then you have to find the sweet spot where the foils enter the water. The splash around the rudder is really suspicious on the current render as most of the fast foiling boats will have a water spray behind the foil, not in front as pictured. Same for the are where the lifted foil meet the hull, difficult to imagine that it can rotate. But the more you got into the details, the more time you will spend, for what? Their goal is to design and build a boat to sell. Their photoshop works was enough to catch the attention and get some nice publicity, I don't think the goal was to fool people. Would it looks better with a more realistic picture? Definitely! Would they gain something extra from this? Probably not and possibly the opposite considering the added effort required.
  24. Philippe Briand : https://www.sail-world.com/photo/208901 Is it a cheap way to gain exposure and publicity? I don't really see any dinghy or light sail boats on their new project list, rather the opposite.

    Teams?

    Would it be so dumb for a lower budget team considering an entry to keep low profile until Nov 30th? I mean they could do with a team of engineers and run plenty of simulation until then, it leaves plenty of time to evaluate the concept in details and eventually find some 'out of the box' ideas which might provide a good shot at the cup (if not, at least have better confidence if this will work or not). With the potential good idea in hand and an advanced design, it should be easier to convince some extra sponsors to join in (making up for penalty fees). Late challenge also allows to recruit the crew later and spare some $$$. For a small structure not yet fully convinced by the foiling monohull, it might be strategically interesting to wait until Nov 30th to apply. Lower risk and higher rewards for them than committing now (without bad publicity to draw back in case they realize they won't make it). The drawback is late start to build the boat and less time testing it but such team would only build one boat and won't have the budget to develop it a lot anyway...
