      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 believe this may be the system that A Class Sailor is referring to. If it's not, it's still an interesting way of solving the problem and something I'd look at putting on my A, if I sailed her more
  2. What about the updating of the sails for the 400 and 200? There was a deck mould update for the 800 and I believe the 200 too... Both thoroughly researched and with an aim of making minimal difference to performance, just ease of manufacture, use and 'modernising' the classes I think.
  3. That is the crash the article is referencing - it was the first event of this season.
  4. Anyone notice that in the last 2 onboards OTUSA have put out, it's obvious that they still have a winch-operated mainsheet, only under the deck for aero reasons?
  5. There is less halyard stretch, although most dinghy sail designs have a softer luff than the stretch in a typical modern line used as a halyard so I expect it is imperceptible in a dinghy of this size with a dacron sail. The mast compression is the same whether you locate the halyard cleat at the bottom of the mast, half way up the mast or at the top of the mast. As one naval architect explained to us......."Hold up a broomstick in your left hand with a 40lb weight tied to a line going through a sheeve at the top of the broom stick.....if you tie the line off by the sheeve or at the bottom of the broomstick, the compression is still 40lbs.......compression is affected by the tension on the main and the equal and opposing force provided by the mast, not where you tie off the halyard" Another trick to prove this......apply max luff tension with the halyard and the mast lock off.....so the mast is pre-bent under compression. Lock the mast lock so the halyard is locked... release the halyard. The mast will not spring back up to vertical under less compression. Old wives/Etchell sailors lore. The definition of mast compression decides whether you think the compression changes. I agree that halyard cleat location does not effect compression at the bast of the mast - that is provided by mainsail forces, standing rigging (not applicable here) etc. However, the mast will be compressed between the head of the sail and the location of the cleat by the halyard tension and any cunningham tension applied to the sail. Having a halyard lock, or cleat at the top, ensures that this compression is only experienced by the very top of the mast, which is the definition being applied here. With an Aero, the halyard cleat is external to the mast, so with the amount that the rig bends it must cleat at the top. Otherwise, the distance between mast tip and where a mast base cleat would be would shorten too much as the rig bends, reducing halyard tension and allowing the sail to sag. If the halyard tension is kept high enough to ensure a tight luff when the rig bends with a mast base cleat, you would, as Amati states, simply create a bow. The definition of mast compression is the down force being applied through the walls of the mast which is equal and opposing to the up force exerted through the halyard (lifting against the sail) and shrouds (lifting against the deck). When you tighten your shrouds, you will create a similar "bow" effect , even though the shrouds are effectively "locked" at the top of the mast. Next time you are going out on your Aero, apply aggressive halyard tension with the halyard lock off ...sufficient to apply prebend to the rig.....then lock the halyard...et voila, the prebend is unchanged. Now agreed that if you stand at transom and pull halyard, you are creating an additional force which is not compression , which will bend the mast. There are a variety of forces that the controls of a sail boat can apply to the mast. Some create compression. Some do not. Its all fun to figure out. Force can turn a corner. The outhaul on a boom is similar. The compression along the boom is the same whether you cleat at aft of boom or at front of boom. Not quite... Due to the sheave at the top, the force the sail pulls downward with is doubled on the top of the rig. With the cleat at the very top of the rig, as on an Aero, this doubling in force is only acting on the top 1 or 2 inches of rig. If the halyard was cleated at the bottom of the rig, as in many other dinghies, this 2:1 action acts over almost the entirety of the rig - from the sheave to the cleat point. Any bit of rig below the cleat point is unaffected by this, and only affected by shroud tension, rig forces etc. This is the reason big boats spend thousands on 2:1 halyards (halving compression between the top of the rig and the cleat point) and halyard locks (eliminating halyard-caused compression forces). This enables them to use lighter rigs, lighter halyards, less hull structure...

  7. I've heard a variant of this: "Starboard" "Aluminium" Sailed extensively on a 12m, had one like it against a Daring (half our length, fibreglass) in the solent: "Starboard!!" "24 tonnes..."
  8. Congrats Bill! Was out there on a JPK 10.80, watching the 40s on the runs was incredible. Hope you go on to have a good season and are made to feel welcome in the Solent
  9. Nope, it's Venture and Venture Keels there as far as I can remember. Great facilities, interviewed there a month or so ago for a job, didn't get it. Easy to see how the Aeros are such a quality product.
  10. Cam cleats are fine, happily used them on Ker 40s/Farr 45s.
  11. Nope, Melges 14 does not sheet to centreline. And neither do many other unarig singlehanded mono I can think of, right up to Musto skiff speed. The only ones I can see that do are the RS600 and the Moth, and they both generate high apparent wind. I own a Laser and have sailed an Aero, didn't notice much of a difference in mainsheet length, much preferred the centre mainsheet falls in the Aero for strong wind gybing on a shifty inland venue. However, I will admit my Laser gybing technique leaves much to be desired!
  12. Look forward to seeing her out Bill, sailed with one of your crew on the Fastnet. Best of luck in the Fast 40 fleet!

  15. UK A-class nationals in September last year, 8 or 9 (2 of those converted C-board boats, the rest factory foilers) of 24 boats were foiling IIRC. None were in 2013. More boats have converted/been brought in to the country over the winter. That's out of a total of 30-odd registered boats at the time of the Nationals. Out of interest, a C-board boat won the nationals and the first open meeting of this year.
