  1. Yep, aka Edake, Bin Rouge etc.
  2. Nah, different one. This is the one Dr Daryl had in his early days.
  3. https://www.youtube.com/watch?v=pEDauGt2dHA From 17:00
  4. she was light blue originally IIRC, red trim stripes
  5. Is this still sailing? Brilliant all the same but it paints a good picture of how hard it would be for a new team to enter this game. https://www.mckinsey.com/business-functions/mckinsey-digital/how-we-help-clients/flying-across-the-sea-propelled-by-ai?cid=other-eml-alt-mip-mck&hdpid=e2ae8d87-aca4-4c44-a8ba-3ddf591149d7&hctky=1404493&hlkid=8f69ec3256044f61bad7df9f9794ffae#
  6. Insightful view IMHO. I agree in no small part based on more recent evidence. The TNZ culture seems to do well when the rules are new and the design space allows a lot of innovation and good gains. But, look back to 2007 and TNZ came within a second in the last race of winning the Cup after the killer type-form had been in place in that class for maybe 15 years and around 100 IACC boats built - totally diminishing returns territory. And, in that and the 2003 iterations Oracle tanked, despite outspending the rest by multiples.
  7. Good assessment. At one level it was frustrating to see the teams making big performance gains during both the challenger series and the cup - that says they had inadequate time and scope to refine their design concepts and how they sailed them. Partly COVID, but also partly the rules - time window restrictions, no two boat testing, for example. These restrictions proved pretty pointless if they were designed to promote more entries. AM started way early, assembled all the right campaign components and solid funding and followed a typical long, incremental, structured corporate-style p
  8. Back in teh day all it took was a passport to be classed a "National" - and I'm sure these two would qualify for a Kiwi passport
  9. Australia punches above its weight in many areas because it is a young country with a prematurely mature economy with an educated population built on a can-do culture with a big inferiority complex about the rest of the world. New Zealand punches way above its weight in many areas because it is a young country with a prematurely mature economy with an educated population built on a can-do culture with a big inferiority complex about the rest of the world and Australia.
  10. I'm sure Glenn would be eligible for a NZ passport by now
  11. Never say never. A syndicate involving some of those characters and the obvious sailors may well have the legs. The design side might be an issue - where to get the right talent. But, it's solvable, just hard.
  12. Unlikely sadly - unless the arms race drops down a few tiers to something more affordable. There just hasn't been another rich dude with enough of an interest in the sport prepared to fund one since 1987, Oatley toyed with the idea a few years back but balked at the cost and I'd be surprised if that family would now pony up in Bob's wake. Marcus Blackmore could theoretically be a candidate but his passion to date has been as a top level owner-driver rather than as sugar daddy for a bunch of pros. Jim Cooney, Christian Beck maybe but I suspect it's out of their $ reach at present.
  13. ...and probably a bit more challenging than usual when the other end of the tape is 40 metres away. I guess you could ask the person at the other end to live stream video to show you where the other end of the tape is.
  14. Hmmmm - who'd want to be a measurer ... ?
  15. Yeah good point but how safe is a foiler for a Disabled sailor? Big crash and a disabled sailor may find it hard to get out of the boat safely.
  16. Baby Hydroptere. Probably about the same time as the prototypes in that program were being flown.
  17. I don't understand the point of this boat. There are plenty of foilers around these days you can acquire, sit on and go fast. What's the secret sauce with this thing? It's clearly not practical to sail around courses and would be a pain to transport, assemble and launch. So why?
  18. Nope, it's to reduce drag via reducing both effective displacement (wave drag) and wetted area (skin friction drag), plenty of designer interviews around that say that. AC75s have shedloads of RM, 7.5 tonnes of boat x a lever arm between the centre of gravity and the centre of lift of somewhere around 2.5, maybe even 3 metres. The Centre of lift (CL) will in theory be on to the straight line between the lift centres of the immersed foil and rudder, and given that the foil carries most of the boat's weight the overall CL will be just behind and inside the foil.
  19. Maybe but the drag at 60 knots boat speed is at least 2.25 x the drag at 40 knots so you'd be needing more horses than that I reckon
  20. You would think so, your logic works, but VOR65's and IMOCAs discovered that keel lift working opposite to righting moment is actually fast. In those cases, because the lift reduces drag faster than the RM increases drive force. I guess could be the case for a foiling AC75 too. It's a bit counter-intuitive for sure, but if the foil has to lift less than the total weight of the boat it can operate at a better Lift / Drag ratio and the boat could achieve higher speeds for the same drive force. Combine a lifting hull form with clever rig trim that lowers the centre of effort (so less RM r
  21. Like any other object moving through a fluid, the drag force on a foil goes up with the square of velocity assuming constant geometry. Google "Drag Equation"
  22. The power required to tow one of these up to over 50 knots would be well beyond the current chase boats I reckon. They can only just get to those speeds without anything in tow...
