    Sorry SailbyDate, obviously, you are not an insider. It is related to the 2013 cup not the 2017 one. Just ask Grant if you want to know.

    For the Kiwis to win the next cup there is one very important pre-requisite: GD must be prohibited to ride motorcyles with any members of the crew. Insiders know why. Happy week

    Not any American C-Cat with a 360 rotating wing in the LAC history ?

    “The America’s Cup regattas hosted in New Zealand in 2000 and 2003 had a significant impact on the New Zealand economy generating around half a billion dollars of total value added per regatta, particularly in the marine and tourism sectors. I would like to come back on this information and look at it as an entrepreneur: You can read a politician who is explaining last cup brought 1/2 billions € per regatta to the kiwi economy. Good, so let's make an investor 's analysis. If you invest 100m$ in a regatta and it returns 500m$ that is a great investment many entrepreneurs would like to invest in. Not to mention all the Hedge Funds managers. It is a 500% ROI That is why not to participate for 5m$ in the last cup, was not economically and financially wise 5m$ can be valued as a Call Option on a 500% return asset. So the Option premium worth 1% of 1 regatta economic return, it is probably a cheap price compared to 6/12 months Call Option on Oracle stock. It should have been a "No Brainer" for the Kiwi politicians to put 50$ instead of 5$, but unfortunatly... The past is the past, and the Cup is in Auckland, so the point would be to optimize the budget from, and on this field I would suggest to investigate some financial engineering solutions which are likely to "leverage" government money for instance. Dear Kiwis heroes have a look at SECURITIZATION. It is off topic, so I will not develop here, but for those who have a legitimate interest in this matter, do not hesitate to PM me. Cheers & Congratulations

    I didn't know steel has better mecanic properties than High Modulus carbon. Thank for the info. At the moment the best you can do to support ETNZ is to try any kind of lucky charms. On my side, in order address Oracle's threat I have implemented some kind of black magic rituals for Jimmy to have hemorroïd crisis during the last races. As long as he will be scratching his ass, he will not be adjusting the foil-buttons. Nothing personnal against Jimmy, I am just an GA & ETNZ supporter. Cheers and Best of Luck

    Has anybody some trouble to have access to the race 8 replay kindly posted by Rudder_NZ ? Cheers

    The winning foils

    As far as I understood Hydrofoil I would say: The low pressure side has almost a constant radius curve all along the section from leading edge to trailing edge, while high pressure side has a more tortured line in order to have thickness at the right place and "Aft Loading" going to the trailing edge, while maintaining a sharp LE. Aft loading would allow you to have the same lift with lower peak velocity at the leading edge, hence delaying leading edge ventilation With more pedantry, I write the same thing than Surfsailor, I apologize in advance. Dougy, there is a CFD mooc on edX website you should attend seriously, we will have peace on the forum then. You see I try to remain positive with you.... and it is not an easy task. Your last post is so candid, you cannot imagine.. Cheers Everybody

    Hi Everybody, On the frontpage of SA today, there is a very intersting interview of ETNZ wing's engineer. Unfortunatly, the video is breaking all the time and many comments are difficult to understand for a non English native. Any idea on how to download it in order to watch it without breaks? (I am not digital native too) Thanks in advance

    The slotted wing presents some advantage in very low wind, where you seek deseperatly for more HP in your rig. But with today's apparent wind on the A-Cat (i.e), the slotted wing is an hudge extra complexity for a very slight advantage. Sailing at 20 knts down the wind with 12 knts TWS will provide you with around 20 knts apparent wind Windward in the same conditions, if you flioat you will have 22 knts AW, if you foil at 20 knts you will have 25/28 knts AW. In both cases you are overpowered, even if you consider the max righting moment hypothesis ( =the lift on the windward foil assumed to be 0+ full trapeze crew). The slotted wing would be most usefull in light wind conditions, unfortunatly in these conditions the Reynolds number of the air stream on the wing is half the Reynolds numbers on a sail+teardrop mast, which probably contributes to offset the theorical extra power of the slotted wing. Regarding the futur of the A-Cat rig or all other foiling boats, I would believe it will be all about drag. Cheers

    As a professionnal sailmaker Randy tried a jib+reduced mainsail on an A-Cat, but it was probably because the original mast of his boat was not stiff enought for a normal sail, so he cut the mast and put a jib instead of buying a new rig set.

    a significant part of the load on the mast comes from the frontstay where the leading edge of the jib must be maintained as straight as possible. The compression resulting from the little mainsail remains a bit mysterious too me, probably lower than for a classic sail+ small teardrop mast with similar area ??? But its aspect ratio is so high that I am a bit confused on this point (Double aspect ratio but half area) Or the tension to hold the leech = the tension to hold the jib ?? more or less Just an assumption any idea?
