      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

  1. AC36 - The Venue

    While they can't put the wing on display for safety reason, they should put a mast and a wire version of the wing, it would allow visitors to appreciate the size of it and it is always easier to picture the whole thing with some reference points.
  2. Larry's AC50 Circus

    ^ And because they don't need to. They can't call it Larry's AC50 circus, or AC anything, and they won't compete with AC audience as people attends AC events because of its name, history, the 3-4 years wait,... But it still the best time to launch this "AC50 like" racing. If they wait until winning the cup back (if they manage to do so), they would look like going back in time and technology to something which took place 7-8 years before. In addition they would be badly hurt if this cup cycle is as spectacular and successful, AC75 would become the new fresh and impressive things, not those AC50's of the past. Thus the best time to launch such campaign is now or in the near future, when we are still feeding of the great footage from AC36 (when we find some). It is now that they have the best reach and possible audience which could divert some from AC but I assume that most will continue following AC anyway.

  4. Larry's AC50 Circus

    Fair point, it would be enough to post the question in various parts of SA. You will get totally different answers depending on the thread in which the question is asked.

    Yeah I've watched all the races these boats have done as well - and you are so right Maybe I didn't express myself correctly but what I mean is that gaps will grow very very quickly if you have one boat sailing upwind at ~35 knts and the other going for a reach at ~10 knts because they stop flying. Did any designer speak about the expected acceleration of those boats compared to AC50? This would be a very interesting parameter as the lower the acceleration, the bigger the gap in case a boat stop flying and the other not.

    ^ Add some big obstacles in the middle of the water (spectators boats to get them close to the action) and then you have flipper arcade mode races. That's an innovative race course... Don't ask who pay for the construction cost, it will be cover by ticket price (in theory)

    True. But if it requires them to go for a reach in order to fly upwind, it can quickly become bad for the competition. If one boat stop flying while the other continue, it will create huge gap and it doesn't align with close racing. Foiling tack will be even more critical than during the previous 2 cups. That's actually my main concern, that boats should transition to fly mode in similar conditions and manage similar tacks in order to have good racing. It's not that fun to see 1km+ lead and it can quickly happen with this kind of boats.
  8. Team NYYC

    Main difference with the logo, this one looks serious!

    Is there a rule to forbid using spars to use the code zero as counter weight by locating it as far as possible overboard on windward when not in use? Is the advantage worth doing so and code zero available enough time? Or is the code zero considered as ballast when not in used, in which case located as described in 9.5? The advantage might be negated by the aerodynamics effect already but could be interesting to have an extra 100kg located near the foil.
  10. Team UK

    The 50M and 75M figures from the Italian are probably mind games. They probably wish that other competitors will enter with that kind of budget, that would surely lift their own hopes... While the serious contenders know that a budget in excess of 100M is required to have a proper chance.
  11. Oracle Team USA

    Picked up during the last group meeting: "Hey you know what? Those guys at SA, you can throw whatever dumb ideas at them, they will keep fighting to explain you the truth. You just have to continue denying them using whatever argument, even making your own, and they will keep spending time and energy trying to convince you. It's so fun, you should try some times." I must admit, they are pretty good at it. Speaking of truth and evidence, I would like video, data, whatever proof that a F1 driver is using his foot to break and accelerate his car. We never see his foot and it would be so easy to have that controlled by a control unit on board the F1... But let's speak of that in another thread on another forum!
  12. I just bought a 'Mystery Dingy'! What is it?

    The hull really looks like a laser 2 to me but the sign on the sail doesn't match. It has a double arrow on the jib, not very far off if you move the two lines from the equal to form another < ... Some facts and figures: http://www.laser2sailing.org/boat/specs.php https://en.wikipedia.org/wiki/Laser_2
  13. Artemis?

    Isn't it the boat used for testing sails by TNZ? Looks alike to me. That would be some coincidence to have someone wearing an Artemis hat nearby. Could they be that they discuss that openly with interested competitors? http://www.nzherald.co.nz/sport/news/article.cfm?c_id=4&objectid=12001609
  14. ^ Great read. Is it the first time they are getting a bit more specific about sails? "The rig is still under development but will feature soft sails, including code zeros for downwind legs. The mainsail concept is likely to involve a twin-luff set-up, which creates a much more efficient wing-like transition from the mast to the sail."
  15. Mothquito

    Probably that the gennaker will be mainly use for those sailing in tandem and not in solo. Some more below. Would be interesting to see on water behavior when they begin sailing this.
  16. Do they also plan to change boats in between races for whatever reason (electric shock which could potentially arm nearby fishes, and eventually sailors)?
  17. Oracle Team USA

    Agree. But his analogy with a cube is the worst you could pick because once you know the dimension of one side, you know every parameter about the cube unlike a wave height (which is very difficult to measure).
  18. Foiling injuries

    I guess it is just about the press focus. People had hands crushed in pulleys before and injuries will always be part of sailing, the forces in play are much greater than the human body can bear (that's probably part of our attraction and fascination as well). Now we are still at the early days of foiling and it looks impressive and it probably scares some people then saying it is dangerous and unsafe. Thus any incident is much more likely to be relayed into the press and people will have the impression that it causes more injuries. I am not saying that foiling lead to less injury, I think they are of different natures but we should always take the numbers with caution.
  19. Actually the AC75 might be less risky regarding cuts by rudder or foils for the on board crew. They will have a single rudder, in the middle of the boat. If a man fall, he is less likely to be caught by this rudder which has a greater lateral distance than for a cat. Regarding the foils, there is less risk for crew members to fall on AC75 than AC50 where they could fall in front, in between the hulls with a higher risk to be caught by a foil. It's really collision between boats which might be scary. Even capsizes which are more likely to occur than in AC50 shouldn't be as dangerous.
  20. AC 36 Protocol

    https://www.sail-world.com/news/201692/Five-Olympic-classes-recommended-for-Review Turning then to cries for females to be crewing in the America's Cup with the VOR Quota system being pushed as the way forward, isn't the real issue that until a female skipper wins an Olympic Gold Medal in open competition, female sailors will not feature on an America's Cup crew shopping list. Looking at the situation through a different lens, what if Gemma Jones had won the Gold Medal in the Nacra 17 in 2016, in a part foiler? Or does so in 2020 in a full foiler - would she be looked at seriously as a potential America's Cup helm? Definitely. And the same for other helms of her ilk who win Olympic medals in the foiling classes. The article is mainly not about AC but makes an interesting point about introducing female sailors. I still think that sailors on board America cup's boats should be selected based on their performance and abilities but it would be nice to have mixed crews and it would probably inspire girls to join sailing as well at lower levels. It might be a bit more accessible for the next cycles if they are progressively getting rid of grinders/cyclors where raw muscular capabilities are more important than sailings. not sure it would happen though. I also have mixed feelings about VOR quota system and teams being allowed to have an extra feminine crew. It is like allowing a guest on board to help with the ballast, not sure they would have critical jobs on the boat. Would still help them to acquire valuable experience...
  21. SuperFoiler Grand Prix 2018

    Does it mean they had to postpone because there was too much wind then they only have 2 boats foiling when racing? No live video on the first racing day is really dropping people interest even before it has started.
  22. Team UK

    As stated in the thread about surrogates, they are probably going to develop most of their boat via CAD design and CFD testing instead of having a test boat. Then there was the question on how do you keep sailors into your team when you don't have any boat to sail onto for 1 year or so... TP52 might not be the most relevant serie for the next cup but at least it will keep the sailors fit and busy (plus teams might have some arrangement so that their salaries get paid by someone else in the meantime).
  23. first surrogate

    Dan makes a good point about the need of a surrogate or not. CFD becomes better and better and they can correlate their data from last cup and it certainly provides more relevant data than a 12m hull on the water. The problem with a scale model is that compromises are needed and some parameters can't be scaled easily (like viscosity). Iterations and optimization are also faster on CFD instead of on water tests.
  24. Luna Rossa Challenge. AC 36

    Interesting to see that they give the equivalent in HK$, I guess it is directed at a specific group which should receive the information. Is part of the financing coming from China? I doubt it is to inform the children making the shoes...
  25. They were apparently able to foil by 13 kn of wind back in 1950, surely they will be able to take off now as well in similar or lower wind speed. Hopefully they will also refined the design along the way. Wonder how much of a problem it is to upscale the boat. The bigger it becomes, the most difficult it gets to fly. Does anyone know which percentage of the weight of an IMOCA is sustained by the foil? To have representative figure for a similar scale boat. https://www.cupexperience.com/blog/2017/03/1950s-foiling-sailboat-monitor/
