    Will Any Team Ever Fly A Code Zero?

    We hear a lot about "loosing rudder grip" etc, and that's when the crashes happen. What I am suggesting, is that they end up with an out of balance sail plan to below water foil configuration and it becomes too risky to even consider the code zero. So the question becomes, would you rather go 7 knots or be on your side?

    A lot is being made of the drag penalty once up on the foils, but there is a balance aspect to consider as well. With the additional sail area, they must not be able to get to their desired settings elsewhere in the configuration once the boat is up and ripping. I'm sure the "structural headstay" as others are referring to it, is connected to hydraulics under deck, and they can play luff (jib Cunningham) and rake fairly easily, which may not be as feasible with the code zero tacked out onto the bow sprit.

    I am expecting to see their third set of foils when it comes out of the shed again. They've got nothing to lose at this point by piling on whatever gear they have been holding back. They had sailors from all the other teams crawling all over their boat, I'm sure they took note of a feature or two.

    I don't understand why you are arguing about this. As a sailmaker of 20 years, I'd expect you would be more familiar with 8 point offsets, and describing 2d curvature. Mozzy is wrong, and you are wrong. The illustration I provided is how you measure mast bend. The numbers aren't accurate because of the angle of the shot, not because the technique is incorrect. Let that sink in before you go off on another four-letter word keyboard rant.

    I gave PERCENTAGES to how much the mast is ACTUALLY BENDING- and qualified them by saying that they are not dead on because of the stated factors. They are far more accurate than a projected line from the mast base, and if the annotated diagram didn't make sense to you, you are the fucking idiot. Calling me a troll is rich for a sub 100 post sock.

    It is absolutely clear that you have no idea what you're talking about. I stand by that the yellow line in front of the mast is a better indication of mast rake, than mast bend. Obviously, these numbers are nowhere near accurate, as the shot is not dead on the side of the boat, and they don't account for mast rotation - so they should be taken with a grain of salt. However, it does accurately depict how fundamentally incorrect measuring mast bend via a straight projected line from the mast base is.

    The "mast" bend illustration is not describing mast bend, but rather rake. No doubt the mast is bending, but not 1.5 mast widths as pictured. A more accurate measurement would be taken from the aft edge, foot to head, and offset measurements made at 1/8 or 1/4 points. I think the thing most analysis is missing at this point, is the balance aspect. They appear to be running more rake, with smaller headsails, effectively moving the COE aft. This would all have to work in conjunction with the COG and whatever insane voodoo physics are at play underwater - which almost certainly have been affected by the foil mods and new rudder/elevator.

    Does @weta27 or one of the other superb NZ photogs have detailed shots of the mast head on any teams boat with the runners attached? Or even better of LR with or without the runners connected at deck level. While I understand "every little bit helps" I just think this whole backstay thing is a bit of a show. Similar to the jumperless rigs in the IACC v5 boats in Valencia. BMW Oracle had dummy jumpers during the lead up, but shed them once it counted- ultimately the team had tried to be too tricky with their equipment, and the gear wasn't reliable and didn't pay off. And with LLPR we have seen early engineering fail in the form of the foil arms, bow, and I'm sure lots more we will never hear about. I hope they keep their eyes on the prize and not get caught up in being too fancy...

    Again with ETNZ and LLPR already committed their final foil designs, what is there to copy at this point? What idea can another team copy from ETNZ's foils or flaps that would integrate into their existing foil/flap config. There is no advantage in waiting to fit them to the boat- Hiding them until the last two weeks would only mean they don't have time to optimize and test different wind / wave conditions. Imagine it blows in the upper range for the last two weeks before the cup, and now they haven't tested the new super top secret foils in the expected light range because some yahoo on SA told them to conceal the foils until the last minute so no one could copy them (ya know cause we showed them foiling too early in 2013). It's illogical. What you're failing to grasp, and trying to cover up by pointing to previous cycles is, the individual boat systems are too tightly integrated, and it's too late in the game, to copy significant ideas from other platforms. Iterative test-driven development doesn't work like that. If you throw a hail mary late in the game, every tool in your development pipeline has to compensate as well. It's just not going to happen.

    As far as copying flaps, I would suspect that the flap shapes are highly dependent on the leading bit (the foil), and again, I don't think you could transplant an ETNZ shaped flap on any of the challenger's foils and expect a miracle. I agree that they likely have new parts planned up until the match. However, they don't have the Prada Cup to deal with, so there is no reason not to show up the line with their best gear. There is no one to dispatch other than the remaining challenger. Performance improvements during the match will consist of tuning and boat handling, not some 11th hour new-fangled mainsail they've kept top secret this whole time.

    100% wishful thinking- and that doesn't address the slight "whole package" issue. I'm not saying modification is off the table- Just that copying a foil is ridiculous and entirely impractical at this point.

    Who is going to copy them? INEOS and AM are out of foils, and LRPP would have had to commit to final designs for theirs by now. Each team is well down their own design paths, and I very much doubt that copying foils would help as the whole foil, platform, and sail package would have to adjust as well.

    They have exactly the same chance of using B1 as the other teams- ZERO. While the hull shapes might be similar, there is no chance the internal structure or layup schedule is the same. They would essentially be throwing away any gained performance benefits from learning how to build an AC75- and out of all the teams, they had the most structural problems (in the public domain) with their B1. The B1s would serve as better spectator platforms for the shore crew than they ever would as a competitor against another team's B2 (outside of the slight possibility that you break your B2 in 1/2 a day before the match). Just think of all the beer they could keep in those crew trenches.

    Have we heard if Ben got his wish and received the FCS code so his team could "fix" it?
