    true, and sailing is very much about minimising mistakes. They've been the best at that, so sailed the best. I think, in the LR losses to INEOS, you can point to moments in the race where LR made tactical errors, or handling errors which have a greater impact on the end of race delta than pure speed. These all get summed up in to the end of race averages, so it's hard to then pull them out afterwards. Race 1: LR missed the hook, lost start, then struggle to bear away twice. Delta was in the teens. Without these errors luna rossa 'may' have won Race 2 (canned): LR were better upwind in the waves, slight edge to INEOS downwind. But overall LR had more legs I felt. Seemed to get less unsettled and have a wider groove. But then they hit the hole and INEOS sailed right by... Race 2: LR got out of phase upwind and lost a lot, then went wrong windward to get out of phase for downwind. INEOS had better speed DW, LR better height UW. Very tight, but I would say INEOS had a slight speed advantage in this race... but marginal. Race 3: LR fudged two tacks. Missed layline. Swung out round leeward mark. And were only half a boat length off winning the race with that final cross. They also never matched up against LR in the light, which is where most would suspect LR to have their edge. So, I couldn't conclusively say INEOS have a faster boat (although if their Cunningham had worked today, maybe it would have been?). What we can say for sure, if the way INEOS is sailed, the crew roles, the division of labour... excellent. Harder to give a metric for this, but I don't think anyone can deny.

    Luna Rossa will be furious, a clearly capable and fast boat, just let down again in a tight situation. I know it's becoming cliche by now to say this, but they must solve the communication issue between Jimmy and Bruni. I can see why Jimmy was calling those tacks, but it clearly wasn't as well practiced as it should be. Obviously, lots of shifts in that race, but these were two situation, where Luna Rossa conceded an advantageous position in an unforced error. They only needed half a boat length more and that last cross penalty would have gone their way.

    What a race! However... I can't help but feel the other teams are losing more than INEOS are winning sometimes. Luna Rossa will be furious. at their race calls through this series and AM clearly have a fast boat. Either of those teams are going to be formidable IF they can get their own houses in order. But well done to the lads on INEOS. You need the boat speed to put other teams under pressure, which they just about have and then they have been clinical in leveraging other teams mistakes.

    We've got more. I chopped out a lot as I wanted to focus on what we could see. I'm not a foil expert at all, so I probably cut out a decent amount of required background to the statements made if an effort to focus down on the key take home points. Personally, I think INEOS have invested in getting a lot of mechanics in to the foil itself, and some of their shape is a concession to this. An unexpected side effect of housing lots of mechanics is the voids, and the air they hold.

    On another note... these ghost races... they're 'crews races' right? I want to see Matt Gotrel on the wheel #letshrekhelm

    Q: Which team do INEOS support? A: West Ham, because they're forever blowing bubbles... Some speculation about the issues with lift on maneuverer exits during the ACWS... thanks to the guys from the forum who's bits of images we've used

    which side was their new foil on? Issues bearing away were all on port tack (so starboard foil)

    I think with the new boom they've given on on anything other than the final 50cm of cloth end plating the sail. The trade off being it now tacks much better and probably gives better control over the other 95% of sail area. I think that's a pretty similar policy to AM who also don't seem to put off my the sail cloth fighting with boom a little. LR deck sweep looks soooooo pretty though. I am in love with that boat. Incidentally, ETNZs boomless set up doesn't always look that great...

    Rules below. I've not seen any restriction yet, but I assume once up and foiling, they generally don't need any more righting moment than what they have from the mass of the yacht. Downwind they don't sail at maximum cant, and quite often upwind they are not sailing at maximum cant either (although some of that maybe be wave, hull shape, and 'style' related). I highlighted in my INEOS weekend review video that they are now using the windward foil for leeward marks. Probably mostly for leeway (to stop skidding out) but it could also be used for extra righting moment at that time. The AC75 Class Yacht is not designed to resist righting-moment created by hydrodynamic downforce on the windward foil. Following sailing trials and experience gained by Competitors, the Rules Committee, with the agreement of COR/D and the Regatta Director, and in consultation with Competitors, may amend this Rule to place restrictions on the use of the FCS including, but not limited to: (a) a restriction of: (i) the amount of negative cant moment (moment in the sense of reducing cant angle) that may be sustained by the FCS; and (ii) the cant angle that may be set for the windward foil; (b) which may be applied at all times, or only in certain conditions, such as: (i) when in a normal sailing mode, and not through a manoeuvre; (ii) when within certain yacht speed or wind speed ranges; and (iii) during certain stages of a race. Such restrictions may be developed through sailing periods, but shall be frozen according to Rule

    So, they can put the fairings on the mast, but as soon as they put the backstays behind them, they also becomes backstay fairings (despite not being attached to the backstay). I read it as back to square one for the Italians... I hope they're not dedicating too much time to this, as I feel it's a lost cause. Sure, have the coffee boy submit interp requests as a distraction for other teams, but I hope the real design team have refocussed elsewhere.

    I think the above. Take off is at ~19 knots, but the snowball effect of increasing apparent wind and increased leeward foil lift seems to happen from 12-15 knots. Often if they get much above 10 knots in displacement, you will see them go for take off shortly after. That why I think leverage is key before that leeward foil is changing the balance and producing lift

    Not in how far the bulb is away from the centre line (extra 0.4m as you say), but also the foil will weigh less water. By how much is hard to calculate, as we don't know the volume of the foil, but if we did, we could compare that to the volume of air and the difference in the volume of air versus the volume of water would be the difference in weight.

    For getting up to speed, initially the biggest obstacle is righting moment. Until the leeward foil has enough speed to produce lift then the only RM they have is weight distribution, and the biggest thing they can do with that is raise the windward foil. Once going, and leeward foil is producing lift the leverage increases dramatically, as the boat is no longer rolling about eh keel, but rolling about the leeward foil. I think once going, but not quite foiling, there might be a tiny fraction of time where more lift could be gained by using the windward foil, but really I doubt it as it's in exactly the wrong place for RM, which you need for power. Obviously, once foiling, they can foil around with two foil reasonably happy, but a a bit slow and we see this 'eagle mode' used for when they need to soak down to a leeward mark. I also watched the onboard pre-start of INEOS and they cruised around with both down. They can maintain a lower foiling speed with both foils down, but... they struggle to get enough speed pre-tacking (they discuss this and at one time lift the windward board to get more speed up, then drop it and tack). But for take off, even in the light, I think they need the windward foil raised for RM / power.

    Yup, I know Harry Jackson, and he has trained me at Calshot. I am member of Harry's club (Portsmouth North End) and did a bit of road racing for them between 2014-2017. I started sailing more again in 2018 so cycling has taken a back seat. But Harry is our club VP. The track is, and has always been undersized. I didn't actually know the boards were once the wrong way as well though! Olympic velodrome is 250m, calshot is about 150 I think.

    Any pictures of the new foil? If there is one?

    Er... HAYLING ISLAND! You forgot Hayling Island! It's got a funfair. And a miniature railway. If that doesn't make it seaside (beside it being beside the sea) then I don't know what does! Oh, and the velodrome at calshot is by no measure Olympic, it's significantly smaller, and as a result has much tighter turns and steeper sides. It's much more akin to a 'wall of death' than an Olympic velodrome track.

    giles scott... Doing rudder pitch which he takes control of when the flight controller has to grind. I think they have rudder pitch in lots of places, helm can do it, it's one of the two flight controller grips as well. The inner wheel is now black, and doesn't have the grip shift... i think it's maybe a fine and course wheel for rudder movement?

    Well, it's the Yacht Squadron, so in many ways a Cowes race track and boats in soton, like for Sail GP might be the case. But for an AC surely they've want it on the waterfront in Portsmouth just like the world series? I can't see the team going to hythe as it's a bit out in the sticks for spectators. I think Portmsouth is actually a pretty great city, the seafront is full of history and Southsea has very nice housing. Nice open common with excellent access to the water (unlike Soton where you'd hardly know you were by the sea). Old Portsmouth and Spice Island are really pretty (where team is) and have had decent investment in the hot walls. Space maybe an issue with the Navy... but, it's a pretty huge port, I'm sure they could find space. If they really wanted, they could redevelop the hard (where Warrior is) which they have talked about for years and put up new bases if it were a permanent move. But... think we are getting ahead of ourselves...

    Yeah, true. But just thought it was interesting in context of a weekend of universal credit for giles calls. What's interesting, is how much more Giles speech is quantitative rather than just opinions on laylines / other boats etc. And that is probably a hint to what he is seeing on his screen.

    Yes, and I think we saw upwind in the waves, INEOS did have good spurts of pace, but struggled to hold that groove as well. I do think the LR communications are pretty decent for the majority, it's just those crunch situation, the leeward helm needs to be thinking 'what additional information would I want as a helm', rather than 'what would I be doing if I was helming'. I might crunch through the comms on all the boats and do a bit of an analysis of who says what, about what topic and when during the race. Chart the information flow of different boats.

    This is a more interesting video... they're a day late as I already did the shout out to Andy Bryson and the tactical app yesterday on my video... but interesting none the less. I've posted in the Prada thread comparing the type of communication Giles gives compared to Bruni in the same situation and this software is a big part of the reason why Giles is able to do that. Gotta laugh, they also did a crew roles video a few days after mine... maybe someone in INEOS is watching?

    Luna Rossa weekend review, including that 'hook or no hook' decision, which, I believe, is kind of a microcosm of their wider issues with their set up. Feel free to rip our opinions apart!

    Last race between the teams decides, so it would go LR way. Although, with all the spare time in the schedule now, you think they could fit in a tie breaker! SI's unlikely to be changed at this time however. Bit of a shame where you lose one team, but 2/3rd of the racing (from a spectators point of view)

    To be honest, I don't think there is anything I would change about my analysis, now we have the word from Terry. The sail gets caught up on the runner and as a result they can't twist off the sail and lose power higher up. From what Terry is saying the runner may have been completely eased, but they just didn't have any more range... but the real question is the decision that ended up with them doing a tack bear away on the face of the biggest gust of the race, which was clearly visible. Main trimmer advises the right hand turn. Dean ultimately overrules and goes left, which Terry admits is a far harder manoeuvre (he pretty much admits the bear away then easy gybe would have been fine). One might even say impossible, if their runner was completely eased and main completely eased. I think Terry suggesting the severity of the gust being a bit of bad luck is probably just soothing the wound for his team. The gust was clearly visible, in the video. They were easing main like crazy before the tack. It wasn't as if they hadn't seen it. The bear away gybe was the smarter move, that's exactly what Paul Goodison called, Dean Barker overruled his advice and went for the tack bear away. From the presser I also think it's interesting how much weight Andrew Campbells call of 'very light' on the other side was given. Because, that's some way before the decision was made (so I pretty sure the breeze had filled across the entire course), and again, to get down the course you need to bear away, and the guy with the job of handling the power is telling you go for a bear away then gybe. I also don't think you can compare Luna Rossa's tack bear away in the way Terry, or some in this thread are. The fact that luna rossa went round the same mark isn't really here nor there in terms of what was right call for AM. In fact, Bruni is saying the better option for them is to bear away (right gate). It's only once AM capsize that they slow it down do an easy tack, get her up to speed (sailing way wide and do a steady bear away). But, the thing I love, is we're talking about crew roles \ decision making and team co-ordination. Whether you sail a 5knot shit box, or a skiff, we've all had instances where helms deviate and overrule (it's their job), or key crew are ignored in the heat of the movement, and it all goes to shit... this is the sailing we recognise and it's great for the event.
