      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

      Moderation Team Change   06/16/2017

      After fifteen years of volunteer moderation at SA, I will no longer be part of the moderation team. The decision to step aside is mine, and has been some time in the works but we did not wish to announce it in advance for a number of reasons. It's been fun, but I need my time back for other purposes now. The Underdawg admin account will not be monitored until further notice, as I will be relinquishing control of it along with my administrative privileges. Zapata will continue on as a moderator, and any concerns or issues can be directed to that account or to the Editor until further notice. Anyone interested in helping moderate the forums should reach out to Scot by sending a PM to the Editor account. Please note that I am not leaving the community, I am merely stepping aside from Admin responsibilities and privileges on the site.

  1. Stick a couple of these bad boys on the foils
  2. Here is a nice comparison between the current world kite Foil Cup winning race hydrofoil - which is Ultra high Aspect ratio.... and another foil ( mikes lab ) lower aspect commonly used in racing.... NZ probably have a higher aspect ratio low speed foil, and USA seem to have something stubbier, not as useful in low winds.
  3. What would happen if they put NZ board on oracle...... my bet is the tables turned. Oracle probably have too much thickness...... take it to the CNC machine, and take out 1/3 the thickness, reduce dynamic drag by 1/3..... presto. definitaly doable in 5 days.
  4. Sometimes advantages can come from the weirdest places. I know some of the kite Foilers testing out new gear , nice and shiny and smooth from the box, experience small cavitations on the fin VMG upwind, they sand the front and rear surfaces with 400 /800 grit, and record 1 - 1.5 kt speed difference upwind.... It doesn't take much, despite all the r & d, and years designing / testing, I would be surprised these guys are even at 90% of what is possible with the current rules.
  5. My 2 cents.... USA could be faster than NZ in the blow, USA need to change their low speed foils !
  6. Well, I think it won't hit mainstream, until they have developed kook proof ride height systems, that takes that part of the equation - out of the equation.... You become less of a helmsman, and more of a Race car driver trying to pick lines and avoid traffic at 40 kts.
  7. Before you get too excited, its a couple years old..... it is foiling in 8 - 10 kts, but not an AC yacht ... Now are they quicker than this thing... probably not in the light... dunno
  8. Welbourn, made one of the worlds' first fully foiling mono's right? http://www.yachtingworld.com/yachts-and-gear/quant-23-on-board-the-first-foiling-keelboat-67953
  9. Yep - and see how low Ben is and he still digs the leeward pontoon in considerably... the second TNZ start to veer at that height, they are sitting too high and the windward rudder is out of the water a good 5-6 seconds before the impact as a result. who knows if they tried to push the ride height up or down, going up would have caused the other rudder out the water, and going down a harder splashdown........ should have dumped the main pressure if that was possible.
  10. So what actually happened to Emirates Team New Zealand just before they started in Race 4? It wasn't anything to do with cavitation. But it is to do with the mast loading, the point of sail they were on basically loaded up the mast so much that it created a nose down pitching moment. This is normally countered by downforce provided by the windward T rudder foil, however, since the speed was still low, and the acceleration / force was at maximum, the inbalance caused the boat to pitch forward, unfortunately because of how high the boat was flying the pitch rate gets momentum, and causes the boat to dive into the water, still under max acceleration.... which perpetuates the problem straight into a pitch pole.. If TNZ were foiling at a lower height when they bore off, the leeward pontoon would have splashed down a lot earlier, before any pitching moments developed, and allowed an acceleration to a higher speed where the Rudder T-foil would have produced higher downforce to oppose the acceleration. Ie a splashdown, to use the pontoon boyancy to stop pitchpole, rather than trying to use the rudder downforce to stop pitchpole , if they tried to use foil rake, they either would have shot out of the water upwards, or dove in even harder My 2 C

  12. So with no racing going on, if you noticed what happened to emirates yesterday..... when their windward rudder got airborne = instand nose dive..... You would assume the skipper tried to counter with full rake, but it ain't enough... the drag causes nose down at higher speeds !
