      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.

      Moderation Team Change   06/16/2017

      After fifteen years of volunteer moderation at SA, I will no longer be part of the moderation team. The decision to step aside is mine, and has been some time in the works but we did not wish to announce it in advance for a number of reasons. It's been fun, but I need my time back for other purposes now. The Underdawg admin account will not be monitored until further notice, as I will be relinquishing control of it along with my administrative privileges. Zapata will continue on as a moderator, and any concerns or issues can be directed to that account or to the Editor until further notice. Anyone interested in helping moderate the forums should reach out to Scot by sending a PM to the Editor account. Please note that I am not leaving the community, I am merely stepping aside from Admin responsibilities and privileges on the site.

  1. Kocher, Your right, re the "problem with Navy ships." In peacetime, with generally smaller fleet sizes, there is great pressure for ships to be multi-role to make sure you have some asset available with some capability. In wartime, its easier to build mission specific ships...Anti-aircraft Cruisers vs. Heavy Cruisers, Destroyer Escorts, vs. Destroyers, Picket Destroyers vs ASW Destroyers. Today, who knows what mission we'll need a ship to perform? There just aren't enough to fill all the taskings...so you need ships that can do alot of things. Turning the LCS platform into a more multi-role Frigate is a result of that kind of requirements pressure. The catch 22 is mission creep and multi-role ships are bigger, heavier, and more expensive, and rarely need all their capabilities at one time... There is alot of talk right now of bringing a bunch of the mothballed Perry's back to active status to get fleet numbers up and to give the current fleet some room to breath and get badly needed overhaul/maintenance time... Crash
  2. We track Nuc ship fuel burn to, as after 13 years or so, even they need to be "refueled." And that means cutting holes in the sides of the ship to get to the reactors. If I recall correctly, we called it "effective full power hours"
  3. Semi, Your right. That's about what a J/122 does. In 10kts of true wind, it goes upwind at about 40 deg TWA at 6.7 or so for a VMG a little over 5.5 kts. Takes it around 655 secs to go 1 mile upwind. Goes downwind at about 145 deg TWA at 10.3, so a VMG of 8 kts. Takes it 450 secs to go 1nm. That results in an average VMG around the course of 6.5 kts. J/122 rates 33 on a W/L course. So the deep draft J-37C should finish 72 secs after the J/122. with an average VMG around the course of 6.1 kts And a shoal draft J-37C will finish 114 secs after the J/122 with an average VMG around the course of 5.9 kts. So the shoal draft keels performance is 3.7% worse than the deep draft keel. In 10 kts of wind. If everyone sails to their rating. If the ratings are accurate. etc, etc. If your a cruiser and/or beer can or point to point type racer (Ajax comes to mind), giving up 3.7% is likely unnoticeable. Crash
  4. So closer to a average VMG of 6.5 kts...so maybe closer to 2-3% difference in performance. More difference upwind, less downwind I'd guess...
  5. A "normal" PHRF boat might sail at kts, but the boat that rates a "0" sails significantly faster than that. Returning to J Boats, a deep draft J/160 or a J/125 rate "0" or close to it. They sure aren't 5 knot average upwind boats. Probably closer to 7.5 to 8.0 kt upwind boats. 7.5kts is 480 secs/nm. So 1% is 4.8 secs, so the performance difference is closer to 3 to 4 percent...but that is still a long way from 20%... I should have said a J/37C shoal draft (UFO Keel) PHRF rating is 20% worse than a deep draft J/37C...but the performance difference is in the low single digits! Crash
  6. Based on my time as an OOD (CVN-70 84-87) while you may not get the OOD directly on the VHF, if a ship hails you on the VHF, it gets reported to the OOD immediately, and if it is ship to ship comms regarding a COLREGS situation, the OOD will normally/typically will walk over to the radio and speak directly to the bridge of the other ship. I know I sure did, every time. There was a serious breakdown of SA on the Fitz. How, and why are still to be answered. Having had to call the skipper (who was asleep in his at sea cabin) in the Sea of Japan and say "Captian, this is the OOD, I'm about to hit someone, and I need you on the bridge" once, I know how quickly things can go pear shaped.... There was also a serious breakdown of SA on the Container Ship.... Anytime you have humans involved, serious breakdowns of SA are a possibility...
  7. As Jimmy Buffett says, its the difference between '...making music for money (Justin Bieber) instead of making music for me..."
  8. Minne, Doh! your right. PHRF is baselined on how long it would take boat "Zero" with a PHRF rating of 0 to sail a mile. A J-37C should finish 69 secs later. and a J-37 with a UFO keel, 15 secs later than a deep draft J-37C Obviously, a deep draft J-37 can't sail a mile in 69 secs.. That's almost 60 mph (using statue miles, and rounding...) so you're right...I'm off by at least a factor of 10! Semi, My math was correct, but my conclusion was all fucked up.. disregard!!! Crash
  9. J/37 Standard Draft, aluminum mast J35 69 69 J/37 5.2' shoal draft J35 UFO keel 84 90 PHRF of 69 for deep draft J-37. So 7 secs is 10% slower, 14 secs is 20% slower...that's on a triangle course. Its 30% slower on W/L
  10. Slap, Your right, forgot that the J/37C could be had with the UFO keel too. Compared to a deep keel J-37, the UFO keel costs 15 sec on a triangular course, and 21 secs on a W/L course according to the suggested PHRF ratings on the J Boats site. That's about a 20% hit from a performance perspective.. As Bob P always says, there is no substitute for draft. What keel type works best, when there is a requirement for shoal draft depends a great deal on where and how you sail. There is no one right or best answer. And as we see in hull shape, marketing (what perceived customers want) has as much to do with shoal draft keel shape as performance does...
  11. Well, note that its really the only J boat that has it, so...and that the modern J's back to a keel/centerboard approach...(J/95 and J/108).
  12. That's not exactly true. It has features and considerations to reduce its radar signature...but it is in no way "invisible" or stealthy...
  13. Given how much force would have been necessary to tear the keel off that boat, I can't imagine there isn't other significant damage to other parts of the boat. Pic doesn't show much...
  14. I've used 5200 to do this on a Santana 30/30. But it had the edge of the deck sitting on an inward flange with one of those slotted aluminum toe rails on top. So the adhesive quality of the 5200 was a plus. In your case, you just re-sealing the individual bolts, so no need for 5200 adhesive capabilities. In this case, I'd skip the 5200 and go with a product that's more sealant than adhesive.
  15. Semi, In most cruising boat cases, its mostly about getting weight down low...and the "shape" is driven by how much mass they need...otherwise they would look like the "wingy-thingys" on a Southwest Jet (which are designed to reduce drag)
