      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. I first met Mead in 1969 at the North American Multihull Championships. His tri (Victor T at 6:26 in the video) was state of the art then and his little tri obviously still is. Lohring Miller
  2. Congratulations on your win. You are still an inspiration to us younger (74) sailors. Lohring Miller
  3. I can't believe no one mentioned the Simpsons. Here pictured dining out in the real Springfield (Oregon). Lohring Miller
  4. Winch controlled kite sailing is being developed by these guys. Simpler systems are available from Wingit. My favorite simple concept is the . Lohring Miller Kite boat K-1 Kite Scooter
  5. You can actually use off the shelf hardware for RC sailboats. I think the Eagle Tree stabilizer (http://www.eagletreesystems.com/index.php?route=product/product&product_id=50) or similar controllers would be ideal for a Moth style two foil boat. Fore and aft trim would be by rudder foil angle while lateral trim could be by moveable weight. Heave height control would still be by a feeler like the full size boat. A fore and aft as well as lateral weight movement would work for conventional multihulls. If a rudder wing is used its angle could substitute for fore and aft weight movement. Lohring Miller

The forum here isn't for posting jabs about others. Hopefully this will remove the reason for further bickering. If people are not interested in a project, they can always use the ignore list or simply move on to something that does interest you. Posts which are only intended to be criticism or jab at someone would be better directed elsewhere as these don't really add anything new and only add noise. Let's please keep the threads constructive. Thanks. __________________Please be polite to all other members. Please respect those who take their time to give advice freely.

  7. The first post in that thread was 11/11/2003 by Tom Speer. The last post was 11/2/13. In between there were over 1000 posts, many by people deeply involved with making today's foilers possible, and over 200,000 views. Is there a better discussion on the evolution of hydrofoil sailboats? I do not subscribe to any other forum where the moderators would tolerate discussions of the type in this thread. On the other hand, I don't subscribe to any other forum that's being sued for allowing internet bullying. Lohring Miller
  8. Here is a great discussion of foilers. I wouldn't consider a serious design discussion in this forum because poor monitoring allows discussions to deteriorate like this one has. Lohring Miller
  9. I'm 70 years old and also built model airplanes as a teenager. I still build and race radio controlled model boats. Along the way I sailed a variety of boats including Lightnings, Thistles, Coronado 15s, and Class C catamarans. In the late 1960's I worked in the engineering department of General Dynamics Electric Boat Division. I promise that they did model testing. I've been involved with designing the . We built a model to test various ideas before committing to the full scale design. Models are a time tested way to try new things without spending lots of time and money. The complex interactions in sail boats are hard to predict, even today. If you aren't an America's Cup team with millions of dollars to spend on engineers and computer programs, models are a great, low cost method. By the way, Burt Rutan won model airplane contests as a teenager. He went on to test radical airplane concepts using a model mounted on a pickup. Take a look at the Scale Composite web site to see what a model builder can accomplish. For those of us for whom aerodynamics isn't our day job, model building is a great way to explore the science. Too bad you grew out of your curiosity and interest in exploring new ideas. Lohring Miller
  10. "If I'm honest I was expecting to see more amps!" At the time we ran the boat (2008), 20C batteries were state of the art. We could have pulled 200 amps from the batteries if we didn't care about life, but the motor was getting hot as it was. Seventy horsepower was more than this hull runs with IC engines. We were running the boat too fast for the design and it showed signs of instability. When we started the project, we only expected to run 80 mph. I have no experience with LiFe batteries since thay have lower performance for our power applications. I run lithium polymer receiver batteries and have had no problems with that gentle application. :Lohring Miller
  11. OMG! That is hugely impressive. So many questions...can you P-L-E-A-S-E post up the specs of that thing? I know lipo & brushless pretty well, so details will be appreciated As for lipo, I find them safer than NiMh This is seriously off topic,. especially in a sailing forum, but here goes. The boat is a Ron Jones outboard hydro design. Mike Bontoft built it at Ron's company, Composite Structures, Inc . Batteries were from Enerland, a Korean company. At the time their lithium polymer batteries had exceptional current capacity and very low weight. Jason Choy, their marketing director, was very helpful in getting 42 – six cell packs of their best batteries at about ½ list price. Enerland was purchased by A123 Systems during this time but they still honored their commitment to us. We arranged the batteries in six boxes connected in series with seven batteries connected in parallel in each box. Mike researched motors and found Jim Husted’s company, Hyper Torque Electric, had provided rebuilt lift truck motors for several high performance electric vehicles. Because of the outboard configuration, they decided on a relatively small, light motor that started life as a 48 volt pump motor. Though the rest of the electrical system could easily support 100 propeller horsepower, this motor was probably only good for 70 horsepower continuously during the kilo runs. Mike designed and built a quick change gear box to increase the motor output rpm to one better suited to the available racing propellers. We ran a standard outboard racing lower unit. Several other venders provided help and components during the construction period. Eagle Tree Systems gave us data loggers that provided invaluable information on the boat’s performance during its runs. Tecknowlegey furnished specialty contactors. Charging the boat’s 42 batteries was a challenge. We finally decided to charge each battery individually with Hyperion Duo chargers. RC Lipos and Rivergate Distributing helped out with the chargers and power supplies we needed. King graphics supplied all the high quality graphics. We used a Zilla 2000 amp speed control. Without the driver, the boat weighed about 500 pounds ready to run. Though our first tests were considerably above the existing APBA and UIM records, we felt there was room for improvement. We contacted multi record holder, Bob Wartinger, for help. He not only furnished setup advice, he gave us two of his record setting propellers to try. This help raised our test speeds from 80 mph to slightly over 100. Below are some pictures of the boat and graphs from the record runs. The graph shows propeller rpm and the voltage and current from one 6 cell battery pack. Lohring Miller
  12. Lithium polymer batteries are safe if you use them correctly. They are lots tougher than lead acid batteries in high power use and lighter than anything else. It doesn't make a lot of difference for radio system batteries, but the lithium polymer battery has revolutionized model power plants. My experience is mostly with RC electric boat racing, but I was involved with as well. The important things are: Use a balancing charger designed for lithium polymer batteries Don't charge at a rate higher than the battery manufacturer recommends Don't over discharge. We use speed controllers that shut off when cell voltages drop to 2.8 to 3 volts Don't draw higher currents than around 40C (40 times the packs milliamphere hour rating) for high quality batteries From the picture below you can see we weren't too worried about the batteries. The boat ran 42 - 6 cell, 5000 mah packs for a total of 252 cells. Lohring Miller
