    Not to mention the placement of their sponsor logos. Also, the main with the integral deck sweeper appears to have a much longer foot length. Assuming the clew webbing 25mm, it's roughly 125-150mm between their reference marks. While I would expect some difference in where the clew ends up depending on the desired camber, 250-300mm is considerable.

    Could also have something to do with Hap's relationship to Mike Sanderson ala the Bella Mente program.

    Luna Rossa Challenge. AC 36

    I am unsure of that. I do believe they both share a lamination process, or maybe even the same manufacturing site? Or maybe Q can build sails up to X luff dimension, and they contract the larger sails to Doyle. Pre 3Di, Doyle sails were very popular among the super yacht group, which would mean they had the equipment/process/space to handle larger sails. I would be fairly confident saying that most teams are finishing their own sails, or at least heavily involved in the finishing of the sails at either North or Quantum/Doyle facilities.

    Luna Rossa Challenge. AC 36

    UK, ITA, and NZL are all using North 3Di, while USA is backed by Quantum. 3Di is a non-woven composite material comprised of thin plys of uni-directional fiber. I could be incorrect, but looking at AM's sails in the most recent pics from Auckland, Quantum are still using "string sail" technology where the strings (fibers) are sandwiched between two outer layers- typically mylar, but in some cases an ultralight woven polyester. I believe they have been using the tafeta (ultralight poly) to attempt to mimic the appearance of the 3Di sails as opposed to the typical use case for tafeta in laminates, durability at the expense of weight. Either way, what you're seeing should be visible on both UK and NZL boats given the right lighting conditions. Each team is likely testing their own fiber layouts (to best handle the loads in a particular area of the sail), and in the case of 3Di they might be able to also vary the tapes they are using to achieve some desired result. Think back to the IACC days when the 3DL headsails used higher modulus carbon (black in color) up the leech and luff, and lower modulus and more forgiving aramid (yellow/gold in color) in the foot and areas subjected to impacts on the rig or deck as a simple use case. The finish (what you're considering sheen) of the 3Di would, however, be very similar from team to team. Edit: It is possible that "external" tapes (HMPE, aramid, or poly, or even a blend) could be applied to 3Di, but unlikely as this is typically reserved for off shore sails which need to withstand a lap of the planet. Inshore specific sails, and in particular sails for the AC would focus more on weight savings and having just enough fiber to support the sail shape.

    Stars and Stripes Team USA is gone

    Forgive me if I missed this, as I skimmed all the new action in this thread. I personally think it's only good for the event to have another team on the line. Realistically, I don't believe their chance of success is much better than Groupama in Bermuda, and I would expect their performance to be similar; Mostly "off pace", but "even a blind squirrel can find a nut every once in awhile". They might take a race here or there, but it's seriously unlikely given the lack of on the water experience. Something I believe most posts have not taken into account is that S+S bought a design package from ETNZ already. Obviously none of us are privy to the details of that agreement or what details may be shared among the teams, or if that deal had to be cleared by the other teams(IT, USA, UK). S+S hull mold may very well have been a carbon copy of ETNZ B1 for all we know. They may even have agreed to share upgrades as they were developed by either team. When you approach S+S as a first-time challenger trying to learn the game, the picture is not quite the same as sharing information with top tier competitors. Here's some wild speculation for you folks... What if S+S had the front bit of their mold and were able to layup that section, and splice It onto ETNZ B1 would it be possible for them to fulfill the CIC constraint? Could their request with the panel include a "we could go to this whole extreme, or can we just agree to let us use the boat for the benefit of the event?"

    I agree that statically a catamaran is more stable when sitting still. However, I14's and other similar skiffs will also just tip over at the dock like the AC75... both skiffs and similar size cats will all capsize on the water, so I don't see why you and others continuously bitch about the stability factor of the AC75s. By that logic, we should stop sailing any vessel that can flip over because they are too dangerous. Why not just take a break from all that and enjoy the damn show.

    No more vulnerable than the AC50's. They had to grind enough pressure into the accumulators between maneuvers. IIRC the grinders aren't responsible for the hyrdo on the FCS this time, so it's just a battery-powered pump that has that job now, which might make it seem more like a penalty.

    Well, only one team has both an AC72 and an AC75... guess you're going to have to ask Dalts to recommission the 72 and do an exhibition race to replace his missing $3mil bucks.

    Not to get in the middle of you two, but it would be fair to point out a few things. It's reasonable to assume that an AC50/F50 would be able to resume sailing after a capsize if it had a soft sail. The wing sails seem to take the most damage from the capsize. Other damage did occur but seemed more superficial, fairings, film, etc.. So I would attribute the AC75's ability to continue sailing more to the rig and sail choice and to the lack of exposed fairings. As far as "The F50s are more unstable than the AC75" is concerned- The AC75 would tip over at the dock without the right precautions. It would be hard-to-impossible to reasonably compare their stability in the context you're suggesting until after the AC75's have been used in an actual regatta and the teams are put into boat handling situations outside of their practiced maneuvers sailing around the course by themselves.

    The Auckland web cam still shows the boat shrink wrapped next to the shed which is still under construction...

    Backup plan.. incase you snap your good boat in half. I believe that ETNZ shipped the decommissioned AC72 B1 hulls and components to SF, but I could easily be incorrect on that one.

    promising, but not long enough. google says the typical parking space is 9 feet wide, so even then those are 10' wide spaces, it's around 10' short.

    And obviously the question to your competely off base question is, No. They don't. Nor do any of the other teams. So what's your point?

    God job! You finally answered! I mean it's only taken you three posts to spew absolute bull shit and make wild false assertions, but don't let the real world get in your way, right? As for your answer on the other hand - "Yes. No question. Watch the video". I haven't seen a video of AM capsizing their AC75. Care to share?
