jeffies, you are unteachable.
anchor with clothesline, if you wish. From: "Jeff Morris" Date: 11/11/2004 8:54 AM Eastern Standard Time Message-id: So you're still insisting the 3-strand nylon is destroyed by stretching 4%? Why do you suppose NE Ropes describes it as having "high elongation" and has a chart showing "working elongation" of over 20%? Don't be such a coward jaxie. Be a man and just admit you made a mistake. Guess that's too much of a stretch for you. "JAXAshby" wrote in message ... no, I am sick and tired of attempting communication with a blithering idiot. no effort on my part will ever help you understand even the most simple of concepts, for for you to accept understanding with another's help clearly shows -- to you -- that you didn't understand even the simplest of concepts by yourself. you are unteachable, jeffies. you probably STILL don't realize that red stop lights are higher than green lights, and for sure when you do realize that elemental fact you will have no idea why. tie up with a clothesline, jeffies. From: "Jeff Morris" Date: 11/11/2004 8:36 AM Eastern Standard Time Message-id: In other words, you can't figure out the difference between nylon and polypropylene. Its a good thing you never go sailing. "JAXAshby" wrote in message ... jeffies, stay tied to the dock. again. you are lost to this universe. still. this subject is way beyond you. as always. From: "Jeff Morris" Date: 11/10/2004 9:45 PM Eastern Standard Time Message-id: I was right, you don't know the difference between nylon and polypropylene. Are you really claiming nylon fails after stretching 4%? Why do you think NE Ropes says nylon 3-strand has "high elongation"? Here's the link again. Nylon 3-strand: 15% working elongation at 15% tensile strength. (OK, maybe 14%) http://www.neropes.com/techdata/3strand.pdf "JAXAshby" wrote in message ... jeffies, go read the damned thing. then read it again, and again and again. then if you STILL don't understand what it says, go look at plaited rope vs elongation, and THEN look at springy mountain climbing rope. 4 frickin' %, jeffies. get your wife to explain it to you. From: "Jeff Morris" Date: 11/10/2004 8:17 PM Eastern Standard Time Message-id: Read what, jaxie? The chart is very clear that the "working elongation" of nylon is up to 25%. Are you confusing "working elongation" with "destructive deformation"? Or perhaps you don't know the difference between nylon and polypropylene. Are you really claiming the nylon 3-strand is destroyed when its stretched over 4%? And you expect anyone to believe that you've ever been on a boat? "JAXAshby" wrote in message ... jeffies, go READ it again, this time let your wife explain it to you. what did you say your degree was in again? From: "Jeff Morris" Date: 11/10/2004 8:53 AM Eastern Standard Time Message-id: You seem to be having serious comprehension problems, jaxie. Time for another refill of meds. The chart in the New England Ropes brochure is quite clear, at least for anyone with a 4th grade education. They don't bother to mention elongation below 4%. The chart shows "working elongation" of over 20% for filament nylon 3-strand. The terms "destructive" and "deformation" are never mentioned. There is some feeling that after a major stress, perhaps over 25% of tensile strength, nylon rode should be replaced. This not a problem for a snubber, which can be considered sacrificial. This makes a good case for downgrading a primary rode and replacing it after a major blow. "JAXAshby" wrote in message ... jeffies, are you a lying sack of squat, or just too stupid to read your own cites? 4%, dood, your cite states, just like I said. Unless, of course, *you* don't know what destructive elongation is. What did you say your degree is in? we would like to hear you say it again. From: "Jeff Morris" Date: 11/9/2004 8:35 PM Eastern Standard Time Message-id: Yet another topic where jaxie can show his ignorance. NE Ropes says at 15% of breaking strength elongation is 15%. Marlow has similar numbers. But what would they know? http://www.neropes.com/techdata/3strand.pdf One can debate whether 15% of tensile strength is a proper safety factor, but for a snubber its not that critical. This works out to snubbers in the range of 30 to 60 feet. Personally, the need to rig snubbers was one of the issues that led me to stop using all-chain and go to a mixed chain/nylon rode. "JAXAshby" wrote in message news:20041109193940.07586.00000403@m b-m01.aol.com... ten foot of stretch on standard twisted nylon is about 150' to 250' of nylon, except under line breaking conditions. From: "Jeff Morris" Date: 11/7/2004 4:55 PM Eastern Standard Time Message-id: Even more important than the "droop" is the limited (almost non-existent) extension available to an all chain system. What its really needed is enough nylon to allow for 5 or 10 feet, or more, of stretch. "Jim Donohue" wrote in message news:rUtjd.90348$bk1.52418@fed1read0 5... "Amgine" wrote in message om... "Jim Donohue" wrote in message news:X2Uid.82404$bk1.80735@fed1read05... The problems is that above 35 knots of wind or so you have a straight rode. Uhm, maybe for your boat. In fact, just last weekend I was anchored out in 30 gusting 45 and neither chain+rope rode was bar-taut. On the other hand, I was wishing I had a bit more chain on both because I didn't have quite enough out for the weather (7:1 on a 7.5kg Bruce, and 5:1 on a 25lb. CQR) as I'd anchored 8 hours before the peak of the blow. To get a reasonable amount of shock absorption with all-chain, use a chain hook on about 30-40' of light nylon laid line and veer out a few more feet of chain. You'll get all the spring you want, but if there's much fetch you don't want too slack a chain to save your bows from a beating. I've never used either a kellet or buoy, but I'd like to experiment with both. Who has used which? Amgine http://wiki.saewyc.net/ See Complete Book of Anchoring and Mooring by Hinz page 113. On the ABYC hypothetical power boat of 45 feet and 15 foot beam the cantenary has 1 foot of "droop"per 100 feet of rode at 30 knots and 0 feet at 40 knots. If your boat is smaller and has a smaller section it may be a little higher. Hinz advocates the use of chain riding stoppers for all chain boats. He points out that all chain rodes are very good at parting or destroying something in high winds. They are also sufficiently noisey in high wind conditions to make sleep difficult. Jim Donohue |
