  1. My wife and I met them in northern Spain the summer before they did that trip. Twin brothers: Maximilien and Emmanuel IIRC. Charming and fascinating guys. We shared a beer or three and compared notes on our respective transatlantic plans. Initially we thought they were mad - they'd just sailed a tiny home-built proa with about 12 inches of freeboard across Biscay after all - but the more we talked the saner they became. They lived on a diet of rice and onions on passage, slept in the open or in one of the coffin-like hulls, and had their foulies permanently gaffer taped over their wellies
  2. Aah, the Valiant Esprit. I really should invest in a drone so I can get a similar shot of mine
  3. Making that prediction once was optimistic in the extreme. To keep on doing it? Well ...
  4. RC also says that with the new big wing the boats are predicted to foil in just 4 knots of wind. That really is extraordinary.
  5. Interview with Russell Coutts in the latest Seahorse says the season final will be three boats "if we are happy with the format". "That is exciting as it reduces the possibility of a one-sided race, and it also allows more jeopardy. The team lying third could come out winning." Doesn't specify whether he means lying third in the final event or overall for the season - presumably the latter.
  6. Picking up on the feathery theme from upthread, I saw this post on gust response in birds' wings on the brilliant blog Fuck Yeah, Fluid Dynamics: "In flight, birds must adjust quickly to wind gusts or risk crashing. Research shows that the structure of birds’ wings enables them to respond faster than their brains can. The wings essentially act like a suspension system, with the shoulder joint allowing them to lift rapidly in response to vertical gusts. This motion keeps the bird’s head and torso steady, so they can focus on more complex tasks like landing, obstacle avoidance, and pre
  7. Four years ago, when Armel le Cleach was in roughly the same spot as Yannick Bestaven is now, six boats had passed Cape Horn. This year the 17th is about to pass that landmark and there are six boats within 200 miles of the leader. This is a truly captivating race!
  8. The counter-intuitive “contrary current gives higher speed over ground” thing does work for high performance boats that might increase their speed by 3 knots for just a 2 knot increase in wind speed. Imagine a foiling boat doing 12 knots downwind with zero current and a ten knot “ground” breeze - and therefore 10 knot TWS. Add 2 knots of contrary current and TWS increases to 12 knots … and boat speed to 13. That 3 knot increase in boat speed exceeds the 2 knot loss from the current so it’s a net gain in SOG. Yes, I know it’s not that simple and you can’t sail dead downwind blah
  9. Great work by Pip Hare and Didac Costa to wriggle free of the ridge and into the circulation around the top of Theta. 36 hours ago they were in a group with Miranda Merron and Ari Huusela and now they’ve opened up a 160 mile gap - which is likely to double or more over the next 24 hours.
  10. This made me smile. I’ve yet to experience this “complete control” thing that you mention, although I have seen it done so at least I know it’s theoretically possible!
