But that all comes down to muscle memory and familiarity. You are publishing your article to the world via the internet and as such, you need to make sure that the information you convey is accurate (which it is not). Are bowlines strong enough for climbing applications? This information is incorrect. Here is my video to demonstrate the point — risk of Yosemite Bowline. Any load testing that I (and my colleagues) do is purely for academic reasons – to probe and investigate the effect of geometry. The stopper knot does nothing on the Figure 8, but is mandatory on the double bowline. By way of comparison, a Figure 8 will jam when force on the knot exceeds 4kN. ), 作成者:KnudeNoggin (未認証ユーザー) 作成日:2020/05/07 - 19:42, One HELLuva lot of bowline confusion would be spared were the proper FRONT side of the knot shown instead of --as has been done since the dark ages-- the back side :: show the side where the main line crosses itself in making that key/bowline-defining loop!! The tying point of a harness is one of the most fundamental point of safety in climbing and is the most frequently tested one. Yes, its standard but it does get anoying if you are back on the ground and it costs you yust about 10 minutes to separate a knot without cutting the rope. h�bbd```b``�������H4�d}"���&�*�~�H�,+X���͒Vi "�r@$C0��5�����v�E��U��H�\�얃 ��G� To commence climbing with a loose tie-in knot strongly implies recklessness and/or incompetence. Yosemite Bowline knot has served me well so far. ����e感�'&�ӭ Score 78. Making statements based on opinion; back them up with references or personal experience. 0 I am not convinced (a single seemingly non-scientific experiment does not tell much anyway). Perhaps it would be good to write more about the bowline variants climbers actually use, as I haven’t seen those above in the wild. The same can’t be said for bowlines with their seemingly endless variations, and therefore the use of these knots to safeguard a fall carries a higher level of personal responsibility and risk for the user. He/she remains hanging in mid-air and then after a brief rest, gets back on the rock and tries again. Please enter your username and password to log in. He’s done plenty of trad climbing and El Cap climbing, you can’t dismiss him as a single pitch sport climber. When people use the term ‘Bowline’ – what exactly do they mean? Your video explaining the failure mode of the Bowline with 'Yosemite finish' is incorrect. People make mistakes tying-in with #1047 F8 (I refer you to the accident reported by Robert Chisnall (17 September 2015 at Lac Larouche, Quebec Canada) where a female climber failed to properly tie her Figure 8 tie-in knot to her harness. Always test your knots before use and consult a professional climbing guide for guidance. For example, if you want to compare particular off-road 4WD (SUV) vehicle against another vehicle, you need to select another 4WD (SUV). It is NOT to declare knot A versus knot B in a pull-it-till-it-yields test and declare the winning knot as somehow ‘better’ than the ‘losing’ knot. 作成者:Daniel J (未認証ユーザー) 作成日:2018/09/23 - 09:35. That means the acceptable probability of mistying the harness tying-point is smaller than 1 in 10 millions, or 0.00001%. Even The Ashley Book of Knots, which is considered by most knot aficionados to be vastly more sacred than the Holy Bible, is a little vague on defining exact characteristics of bowlines. I don't want to compare the pros and cons of figure 8, double bowline and Yosemite bowline. The internet is pretty much the Wild West in terms of reliable technical information on climbing techniques, more of a repository of opinions than facts. Good information, I have now amended the article to include this. The Great Outdoors Stack Exchange is a question and answer site for people who love being outdoors enjoying nature and wilderness, and learning about the required skills and equipment. (A similar tucking is recommended (by me) with that DAV-recommended tie-in. Yosemite Bowline knot is one of the most popular variant of Bowline knots used by climbers, notably for the harness tying-in point. I learned to tie a single bowline sailing as a kid by tying a half hitch, and then inverting it. With both knots I am comfortable with omitting the stopper knot - because after several month of usage I never experienced the knots to get loose or untied. I also find it fascinating that Adam Ondra uses a simple single bowline. All offer ease of untying after loading, and therefore they present themselves as viable alternatives to the Figure 8. Conscious incompetence; and At the time, neither…, Fifty Classic Climbs of Australia – Community Poll, you can download his masterwork on the subject here, Offset Overhand Bend (AKA Euro Death Knot), https://igkt.net/sm/index.php?topic=6773.msg44540#msg44540, Gear Review: Sea to Summit Ultralight Sleeping Mat, Gear Review: La Sportiva TX4 Approach Shoes, Gear Review: Scarpa Zen Pro Approach Shoes, The hows and whys of tying in with a Bowline, You're doing it wrong: Lead Belaying with a Grigri, 50 Classic Climbs of Australia - The Janicepts, 50 Classic Climbs of Australia - Logan's Ridge, A Fixed Eye (which does not move, as compared to a slipknot). bowline step by step keyword after analyzing the system lists the list of keywords related and the list of websites with related content, in addition you can see which keywords most interested customers on the this website. If you need to add a ‘stopper / backup’ knot – by definition, the knot isn’t secure and stable. This knot carries the designating number of #1010 in the Ashley Book of Knots and was invented for maritime purposes and was never intended for climbing contexts. I think you have a responsibility to correct your content. It’s the standard, and I can’t see sufficient reason to change it. Typically, the ‘client’ is a total novice who is just along for the fun and thrill of the climb. A collar (which captures the standing end), and perhaps most importantly, A nipping loop (which is free to compress with application of load), Securing the tail (either by virtue of the knot itself or in conjunction with a Double Overhand AKA Half Fisherman’s), Increasing the number of strands captured by the nipping loop (which increases friction on the tail, as well as increasing the radius of the loop and thereby lessening the stress caused to cordage by sharp bends). I used to go for the re-threaded bowline but it uses way too much space on the harness so adding a PAS gets a bit tight, so imo this variant is superior since its only 1 loop but its also stable and secure. 3. 274 0 obj <>stream Yosemite Bowline knot is one of the most popular variant of Bowline knots used by climbers, notably for the harness tying-in point. One advantage of bowlines is that they are Post Eye Tiable. Several months of usage is nothing in climbing. The disadvantage to these knots is that they are often harder to tie and harder to inspect. You are publishing your article to the world via the internet and as such, you need to make sure that the information you convey is accurate (which it is not). One would presume that ‘they’ could select and use any knot they desire. And it is critically important to understand that there is nothing wrong with that fact – there is nothing sinister going on. The EBSB does not require a stopper knot, but I still almost always do one. Summary of failure mode: I know a couple of “husky” climbers who have used this, including the irrepressible Mike Law in the current incarnation of his climbing career. Lead climbers (in particular) need to be ‘consciously competent’. Load testing is simply a tool to investigate the behavior of a knot structure under various loading profiles (eg hoop/circumferential loading of an eye). So after reading a bit about bowlines and its secure variants to tie into i made this how-to guide on the EBSB Bowline which is both stable and secure for lead climbing. Well done Mr. Gommers. Gommers observed that the collar of the End Bound Single Bowline (EBSB) was able to be manipulated under 10kN of force, which is to say that you can place a metric ton of force on the knot and still shift the collar by hand. 作成者:KnudeNoggin (未認証ユーザー) 作成日:2020/05/07 - 19:38, Before this runs into another venting verbosity from u-no-hoo, I suspect because of that it will be less safe than a regular bowline or the double bowline. Interesting post. Also, another advantage is the rope-end is at the outside of the knot and hence is less likely to catch a harness or body, whereas in the standard Bowline or Double Bowline, the rope end and the stopper knot near it touch and catch surrounding things like a harness all the time. The main problem with all the various backed-up bowlines as tie-in knots is that everybody has their own slightly different version, so nobody can reliably partner check them at a glance.
