      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. That's it, I'm an imposter... Or maybe, I know what the AASHTO 93 equation is. Maybe I have the design guide sitting on my shelf, as well as the DARWIN software that goes with it. Maybe I didn't have to search online it to figure out what it was, or how it is used for pavement design. Maybe I also have the old MS-1 thickness design guide, the MEPDG design guide, the HERS software, source code and design documentation, the PHT software, source code and design documentation, and the NAPCOM software, source code and design documentation. Feel free to kick your google-fu into high gear and find out what each of those does as well. Maybe there is a blog out there with enough information for you to form an opinion on whether LTPP is an appropriate source of PCC strength information for the HERS models, whether the Witczak Estar model should be used with HPMS data, or whether PHT should use the World Bank traffic/distress relationships. Be careful though, you might find real information from a real engineer, and you wouldn't want to use that... Yes. it is true that a heavy truck does much more damage than a car. The forth power rule is an old concept, but fair enough. The disconnect that is happening here is how that is applied to pavement design in original construction and rehabilitation, and that is what I have been trying to address. To put it simply, while a certain truck may do 5700 times the damage of a car (in simple terms), a roadway designed for 100% trucks would not cost 5700 times what a roadway designed for 100% cars would cost. The 1997 Federal Highway Cost Allocation Study puts new pavement costs at .14 cents per mile for autos (2 axles under 10k), and .42 cents for a 60k five axle truck (pretty average). For rehab, the costs are .59 cents for autos, and 1.86 cents for a 60k five axle truck. The NAPCOM models used for the study are based on the 1993 AASHTO guide, which were the best available at the time. Coming soon, we will have the Comprehensive Truck Size and Weight Limits Study, which will use more current models, based on more current concepts. It might suggest different allocations, but they wont be orders of magnitude different I am sure. The guys who do these studies do not have an agenda. They are not funded by trucking companies or big corporate interests. They are typically funded by federal or state R&D funds, and are honest attempts to accurately account for the costs of a given vehicle. Or you can believe random internet articles...
  2. It does work "that way". The issue with big weights is until you go steel reinforcement (which most metropolitan areas do in their highways in places with high commercial traffic -you don't want to see the price tag for doing that in all the nation's highways) you're stuck with how flexible your substrate is and doubling the thickness of the surface doesn't get-r-done. If it were that simple nearly every right lane would already be doubled. Your highly creative theory is based on a flawed view of current reality, the numbers of truck on current roads compared to the number of cars is no where close to one-to-one, yet the right lanes get hammered to shit. It isn't a creative theory, it is the AASHTO 93 pavement design guide. While it isn't the most current design guide, it is still commonly used, and it is the same guide that everyone is using to say a truck does 4000 times the damage of a car. Some people actually do this pavement design stuff for a living. Feel free to think you know better...
  3. The problem with many of the articles that talk about relative damage potential is that they don't talk about costs, and then everyone just assumes that costs are proportional to damage. It doesn't work that way. Lets build two roads. Road 1 has 2500 vehicles per day, no trucks. Road 2 has 2500 vehicles per day, all trucks. Designed properly, Road 2 is about 2x the thickness of Road 1. If we assume that construction costs are roughly proportional to thickness (close enough), then we see that the road construction cost assignable to the average truck is only about twice that for the average car. Sure, it isn't a proper cost allocation study, but I think it makes it pretty clear that the cost multiplier for trucks is far from the 3000 or 9600 that some of these articles would lead you to believe, and probably much closer to a typical user fee multiplier seen by a truck today (3 or 4 maybe?).
  4. Wadding up your brand new boat on the third day of first big race sucks. Took us 6 months to get a new mast from Nacra, and we had to have a local machine shop reproduce some parts that we weren't willing to wait for (mast base...), hopefully SI is a bit more on the ball...
