    Hope you don't have to sail against Bangladesh.

    Still trashing Deano, you will probably trash Burling when he sells out to the highest bid, because he probably will and why shouldn't he ? Plenty of precedent.

    What's ETNZ' s official budget this time around?. Must have a huge payroll with all those serious blokes scurrying around in black kit.

    I vote for the big boy pants, seems like deja vu to me. ?

    It's only Force 5, a strong breeze, you kids need to get outside more often

    Everyone is fallible, don't read to much into it. Spithill is pretty good at getting into people's heads though, this could be a tough one for Burling.

    All still ranting nicely I see, well better luck with this one than the last go around.

    Can't believe you guys are still talking about this. OTUSA outsailed ETNZ, they were the better sailors with ultimately the faster boat. If they had got the same performance right out of the box they would have whitewashed ETNZ. In the end the results make ETNZ look better than they really were. Sorry to all the Kiwis for wasting all that money and emotion, I was pulling for you but the end result was the correct result. I saw every single practice, catastrophe and race first hand and close up, it was a great spectacle and I wish it were to be repeated. But it's nice to have the Bay to ourselves once again and business is way up from last year.

    I think AR's problems are wing related sailing the downwind legs. The wing just looks wrong, camber appears to reversed in the lower third. I can't put a finger on exactly what it is but it doesn't look fast and apparently it isn't. They do seem able to sail a little lower than LR.

    Seeing AR first over and accelerating was brilliant, for a brief moment I thought we were watching a truly unbelievable scenario unfold, and we still could. They could go home happy now but I would love to see them get at least on win.

    I don't know about the beam issue but I did hear that the boat is overweight, can't confirm that however. Probably shouldn't relay rumours but hey that's what SA's all about right?

    Well they are disturbed enough to copiously crap all over them. Maybe we should spend more money.

    AR always looked solid during a bearaway, I have watched them doing just that at least a dozen times and the boat handing has always been excellent and the lee bow never seemed to dip the same way that OR 1 used to. There wasn't an unusual amount of chop or wind that day, I can state that because I was physically out there. Somebody has raised the possiblity of a collision with a semi-submerged object and as far as I know that hasn't been discounted, failing that it seems to point to some manner of structural faliure. Terrible day for everyone but I don't personally believe that the event should be cancelled,postponed or moved to a more proven design, I was initially a cat skeptic until I saw how well JS handled OR 1. These boats will work on the Bay, I don't know if the process can be made any safer, Artemis was out there with the usual armada of support vessels and despite their best efforts there was a fatality

    Just to be sure we're talking about the same tails I was looking at the ones on the rear faring. There may also be some on the solid bit of the tramp. I'm fairly sure the solid tramp is there to create an end plate that increases the effective aspect ratio of the wing. That would reduce induced drag from the wing. The tails on that, if there are any, might suggest that the gap is effectively closed if they didn't flow steadily from the weather side to the lee side. WAG: the rear fairing may also interact with the wing such that it increases the effective span of the wing. I believe the total force from the fairing would point aft and up at least on the lee side but again the induced drag of the wing would be lessened. My theory (ahem) is that the rear fairing can translate the tip vortex to leeward sort of like a winglet. Seems plausible enough to consider but I wouldn't bet a round of drinks on it. The simpler and more likely reason for the tails is that they want to make sure the fairing are working as fairings (ie. with attached flow on the recovery section). So possibly drag reduction, based on what I saw out there today it didn't seem to have made much of difference, which is to bad because I would like to see them pull something out of the hat.

    Which brings up my next questions which is what are they trying to achieve? Are they trying to lift the back end or keep it planted in the water? Can it generate any fwd motion or has it just been modified to reduce drag? To verify if the fairings are working? If the flow is detached the fairings for sure aren't right. I wonder if there is some interaction with the sail? Probably not an ideal placement but despite the gap there might be some effective increase in the aspect ratio of the wing... Maybe... Would expect to see a leeward deflection of the telltales on the lee side of the fairing if so.
