      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 work on FEA for commercial ships (and the occasional toy). FEA utilization has gone through a few evolutions in response to the market condition and the experience of previous ships. in the 1980's it was used primarily to cut the lightweight of the ship and to support the introduction of high strength materials. Unfortunately that went too far and the incorporation of fatigue analysis brought the ships back into line. In the next few decades shipyards became very competitive on price, and did everything they could to "optimize" the structure for build-ability and weight. The worst examples of these are referred to as orange ships because the entire ships looks orange in the pretty green-to-red FEA pictures -- i.e. no margin for error or unexpected circumstances. Now FEA is being used again to bring the ships back from that extreme and to a more realistic structure. The next evolution is likely to use a greater incorporation of vibration and buckling analysis to again pull steel out of the ships. The Class Rules have also been lagging behind the analysis and experience curve with the last major change initiated about 10 years ago and the results (generally positive with some complaints they went too far and others they haven't gone far enough) only starting to come in now. However, it now appears that a ship built to the minimum Class Rules is finally close to acceptable again whereas the previous Class Rules would have approved a woefully inadequate ship. As Bob notes, experience is still one of an engineers greatest assets. You have to be able to look at a structure or drawing and intuitively know if it is "right" or "wrong". When using FEA I have found it very important to know what the answer is before your start, that way you can quickly find errors in the model or can identify and investigate unexpected results. In that sense, FEA is a poor tool if you are not planning to change the structure from the standard, successful designs of the past. However it can be very powerful when designing a unique vessel, incorporating new materials, or reducing weight and cost. For yachts I agree that it is unneeded cost ad time for standard, robust designs with no unusual features, structurally speaking. Yes, racing boats are a good use of FEA, but I would argue that it is money well spent on large-run production boats as well. My goals on the production boats would be to ensure that critical areas -- keel joint, deck joint, rudder, mast step, chainplates, etc. -- are sufficiently strong, and also to reduce construction time. Any weight savings I expect would be negligible but a welcome dividend. I know that many of the large yacht design firms do currently use FEA in this manner.
