      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.

  1. Thanks, that is helpful. Maybe I should look at some of the foiling week presentations.
  2. Doug, thanks for your suggestions, but it doesn't really address my question, and I am familiar with Tom Speer's explanation of the link between leeway and angle of attack on foils that curve upward. But I prefer not to jump straight to the conclusion without understanding the analysis. My question essentially was how do Z foils provide stability.
  3. This seems like a good thread to ask this question. I recently acquired a boat suitable for experimentation and I am trying to get up to speed on foil developments. Hence, no hidden agenda or judgement in my question. i keep reading that the Z foils are heave stable while all the other alphabet foils, except T, are not, but not any discussion of why. I am assuming that it is because the angled portion of the Z breaks the surface of the water. In that respect, are they simply a version (albeit a very sophisticated modern version) of the "traditional" angled surface piercing foils of the type Hydroptere uses? The boat, which was a gift, is something like a 20 year old, 16 foot, miniature version of Hydroptere with some clark-Y foils. The amas are pretty clunky and I am free to experiment on whatever goes on the ends of the crossbeam. Any suggestions on where to get technical data on modern Z foils?
  4. Yes, straight, surface piercing foil boats by Hydroptere, and all those older V foil boats did without trunks. Tom Speer used to promote a foiling trimaran that looked like it was in the middle of a veritable spiderweb of foils. It just seems to me that all those C, J, L, Z yada yada foils could be deployed without trunks as well. The inner edge might have some structural advantages, but I think the outer edges have the advantage of a larger spread between the foils.
  5. I am not quite sure what this means (I really dislike analysis by metaphor), but I don't think so. A lot of catamarans have the trunks themselves located off the centerline of the hull with no problems. Certainly there is a long history of successful boats with leeboards, which are not part of the "core structure." Some catamarans have a single daggerboard on the centerline of the boat, not even in contact with the hulls at all. I have never heard anyone asserting the the boards have to be located any particular place for structural, rather than balance reasons.
  6. If you are going to fly, it seems to me that daggerboard trunks add a lot of expense and weight for a suboptimal positioning of the foils. Wouldn't it be a lot easier and lighter to build some sort of leeboard style racks on the outside edges of the hulls? This would: -put the foils farther out (slightly?), -could allow for a lot more flexibility in foil shape, -could avoid potentially catastrophic damage to the hulls and foils with a "weak link" in the racks, -could reduce the weight of the boat (trunks are substantial and heavy) -reduce the cost of construction with external racks instead of trunks. Sure, the hulls don't provide any endplate anymore, but of course they don't when you are flying anyway. When you are not flying, you are moving slow, up to maybe 5-10 knots? At those speeds, you don't need to worry about cavitation, ventilation, etc. So, why bother with trunks? Unless you are worried that it makes you look funny. Larry Forgy
  7. These boats are a lot more close winded than I realized! 1 BANQUE POPULAIRE VIII Armel Le Cléac'hFRA18 SOG: 7.5 kts DTL: 0 NM VMG: 7.2 kts 24h: 216.5 NM COG: 36 ° DTF: 4991 NM TWD: 28 ° TWS: 6.8 kts TWA: -8 ° AIR: 24.6 °C
  8. Did Nandor Fa just accidentally sail into the exclusion zone? The tracking shows him doing this odd 270 degree gibe, but I don't see any mention of it on the VG web site. I am rooting for all the over 60 guys in the race, and he is a real inspiration!
