  1. Not that it’s the biggest difference but I’ve heard the helix structure used in the mains on the North boats is a significant advantage. Far better control of the luff of the sail, more shape for more power, and less stretch for more consistent shape. Guesses are that the sails on AM are 8-12% heavier than the other 3 boats. AM tried to get North to give them blanks and do the finishing themselves and rebrand them, but North declined. It’s a legit technology. Still, there’s other issues with that boat that are bigger than that right now. But they know they’re at a deficit on the sa
  2. Are these new foils or the same ones from the capsize?
  3. I'd feel better about AM if they were owning their mistakes. Instead the boat goes quiet when things aren't going their way. The other boats are great examples of how to communicate in a race. AM just isn't. In the media they lay the blame on things they have no control over - the wind, course, etc, instead of taking ownership of the things they are screwing up. It doesn't mean they won't turn it around, but they aren't in a good place right now.
  4. Doesn't this setup for good counterflow for the NE sea breeze? I'm not sure if the sea breeze is NNE or ENE, but it looks like the gradient should help the sea breeze today, no?
  5. I was just offering to help him. Works great for me with SurfShark in the US. I had issues with NordVPN (not related to watching the AC stuff) and finally gave up.
  6. Did you get your VPN sorted? What device are you using it on?
  7. Use a VPN and set it to Canada. If you don't have a VPN, I use this one: SurfShark
  8. I was just giving myself a hard time. Cheers.
  9. Of course I try to be nice and get made to look like an idiot.
  10. Do you know if the yaw of the boats is similar? I don't know if that data is included but some yaw from NZ would explain some of the angle difference, although not all of a difference that large.
  11. The area you're looking at gets bigger the further away it is. Think of a camera outside, where right in front of the camera it only shows a few inches but far away it shows vast distances. When one object is closer than another it has less distance to cover to cross the screen, so viewing two objects moving at the same speed will have the near object move across the screen more quickly and appear to be faster.

When one object is closer than another it has less distance to cover to cross the screen, so viewing two objects moving at the same speed will have the near object move across the screen more quickly and already to be faster.

  15. Would someone explain the interpretation on main measurement in layman's terms? I'm trying to visualize the hollow, distortion, and how bridging them allows the sail to be cut smaller than measured area. Regardless, it's quite clever.
  16. I'm just an armchair doing this in my head for fun so I could easily be wrong. But I view the air flow as front to back primarily and secondarily from top to bottom.
  17. Ah, I see what you mean. Although my understanding is that a vortex can work as a seal rotating either way. One way is just more effective. No? I'm visualizing the vortex flowing down next to the skeg, which I think is opposite the way you see it, then returning air away from the skeg at the water to form the vortex. It wouldn't be a perfect seal and would leak plenty of air under the skeg.
  18. Interesting point. F1 is essentially a niche field of aerodynamics that focuses on vortex management. In F1 they use vortices to seal the floor to the track, especially around the rear tires where they have tire squirt. The better you seal the sides of the floor, the better the diffuser works to create downforce. I think what they are saying here is that creating a vortex on the skeg will provide a better seal than other designs when the gap from the skeg to the water isn't zero, which is most of the time. And that will create a better endplate effect. AM seems to be going fo
