      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. Just a thought why don't you go sailing together on the Searunner and put the Leopard 38 into management with a charter company. Not wanting to nix your chances of a successful relationship with your boyfriend but if you break up he can go back and get his boat and you can both get on with your life if the worst comes to worst. That way ongoing payments to the cruising kitty from the Leopard 38 while it's in charter as well.
  2. Having purchase a spool of carbon from Rob I can confirm it's brilliant stuff. When you have it lying around you just keep finding uses for it.
  3. Just out of interest how is that calculated in MOCRA? Is it a fixed percentage?
  4. I think there is due to their sails, one of Phaedo's sails is non standard.
  5. Well you know the old expression "If you have to ask"
  6. Have you had a chat with Martin Fisher? He did the foil design for Jessica Rabbit. I think she displaces about 6 tonne I recall he mentioned at one stage that the tooling was still available. I'm not sure if this email address is still live but worth a try perhaps. Martin Fischer via Ferrarese 67 , Bologna 40128, Italy Email: fischer@traviata.bo.cnr.it
  7. These might suit out of the racing Formula 40 "Bisuits Cantreau 4" T foil rudders included too. http://sailinganarchy.com/classifieds/show-ad/?id=2673
  8. Not sure on the details I'll see if I can chase up some info. Some 920's like Big Bird have been sailed hard with no problems.
  9. From a performance perspective the 920 is superior better floats with more volume the Crowther Bucc 33 is more of a cruising trimaran. The only negative I can think for the 920 is beam breakage a few have broken with Akimbo being the most recent.
  10. A little more video of the Rapido in action thank's to Paul: http://youtu.be/tUV3gt0qu3Y
  11. Tony Grainger put together a pretty good summary of the cat versus trimaran argument on his Rocket Factory Trimarans website he discusses WSA under the drag transfer effect heading: http://www.rocketfactorytrimarans.com/design-features/what-makes-trimarans-fast/
  12. Okay, you've convinced me that at this scale a tri has a number of clear advantages over a cat which could still hold even with a theoretical robot crew and no humans on board (though I can't work out how there's less wetted surface area in light winds than with a cat). But is this still going to hold as foilers take over? With more sailing done at speeds where the apparent wind is far forward, having a pair of rigs on two amas may be more efficient than a single central one most of the time, and the extra height of the boat over the water will provide more freeboard in all the conditions where it's most needed. Good question, I don't know but I still think that foilers will spend quite a bit of time with their hulls immersed or partially immersed in ocean conditions. The Gitana team for example have stated that their Ultime foiling project will function well across a range of different states foiling, semi foiling and displacement so clearly they believe good performance in each of those modes is important.
  13. I think you are overcomplicating a simple concept, trimarans have more righting moment because they can be wider for a given length. They also allow you to keep freeboard and windage under control due to dihedral. If you want to calculate righting moment just multiply half beam by weight for a rough measure. The extra righting moment has pros and cons because all the gear has to be significantly stronger but it does allow a larger rig. Surely a cat can be just as wide for the length, and it doesn't need any extra strength for that as all these tris have to be able handle the stresses of flying the main hull anyway. If we have a boat run by robotics and no humans on board, what vital service does a middle hull provide that a cat can't duplicate in a similar way without dragging an extra hull along for the ride? The middle hull of a tri helps support the mast. A wider cat means the cross members have to be stronger as the forces will be greater. Given that the tri can fly the main hull, the cross members on a cat shouldn't need to be any stronger than the ones on the tri as you have the same forces being applied through them, and any structure in the main hull that helps support the mast can be duplicated without adding the whole hull. On the AC72s we saw structures designed to do that job without adding a central hull. A cat could be as wide for it's length but the beams would be massive and then there is the problem of seakeeping with those big beams. It's possible but it means that the hulls need lots of freeboard for wave clearance due to demi hull separation. A trimaran gets around that take a ORMA 60 as an example most were square at 60' wide that meant that the effective beam between the hulls was 30' which is acceptable. A 60' wide square catamaran would require lots of freeboard and very arched beams to have adequate clearance to prevent beam slamming which is very hard to engineer without adding excessive weight. The other reality is that no multihull that is racing offshore is going to be flying all hulls bar one all of the time sure you have to engineer for it because it will happen but at many times the hulls will be immersed so you have to consider how the boat performs in those conditions. In the light weather a trimaran does better due to less wetted surface area and as the wind increases it has a wider band of performance that can be exploited. Also consider crew accommodation on a trimaran versus a catamaran you have to put the crew their supplies and the boats equipment somewhere. On a trimaran it's easy put it all in the central hull and keep all the weight out of the floats. To achieve that on a cat you need a central pod which adds windage on top of centre of your already heavily arched beams and you elevate the CoG. A single rig is generally accepted as the way to go performance wise so that means your heavily arched beams also have to carry mast compression loads in their centre. Add to that the more beneficial righting curve of trimarans and the reasons to go with a catamaran start to diminish the larger the boat gets. I don't think there is any knockout blow in the trimarans favor just little things that add up to a significant advantage in the end.

  15. I don't think so but the sample size is so small it's hard to draw any conclusions. Tahiti Douche appeared to have the performance to win outright but was never a well funded program. http://proafile.com/archive/article/tahiti_douche Isn't the sample size every ocean race open to mulithulls ever held ? Well if that was the case then the trimaran would be the clear winner at least on the professional circuit but there were so few proas built and raced it's hard to get a good feel for their overall performance in the racing context. I can recall Michel Desjoyeaux talking about racing Tahiti Douche and noting that it was incredibly technical to sail so that also could have contributed to their overall lack of popularity.
