![]() Zeppelin/Rosendahl Bend Now look what we have here. Just about the best way to tie two ropes together there is. True. It's secure when tugged even when initially unfastened and dangly, and its breaking strength is apparently around 75-80%. Now that's what I call REAL ULTIMATE POWER. |
![]() Granny knot. The simplest, but weakest 'knot' in existence (most often used for shoelaces) |
![]() The reef knot (square knot), usually used to tie two shoe laces together (or its close cousin, the granny knot). It can be used as a 'hitch' - like tying to the chair in the above picture, but I wouldn't advise it for critical jobs. |
![]() Oh sure, it looks all secure now... Any knot used for a hitch can be used to tie two rope/string ends together too, and vice versa. Here we have the crap reef knot again. The reason it doesn't look like a typical shoe lace knot is because the ends are not 'slipped'. Slipping the ends (making a little loop by turning the rope back in on itself) can be done on any knot (even the mighty Zeppelin bend, as if you'd need to), and makes it easier to pull a knot undone, at the slight expense of security. |
![]() ...but this can happen all too easily! |
![]() If the Grapple hitch ever appears to jam, then try pulling the small loose end, until the knot 'rolls over', when it should be trivial to untie. Admittedly, the Grapple hitch is not always adjustable, since it can pull taut when you pull the main long loose end. This is both an advantage as well as a disadvantage. The advantage is that you can throw the rope high over a post from a distance, making it great for tying a knot from afar. The downside of course is not being able to make the rope any length you like. However, it you pull tight on the rope end near the knotted part, then for most rope types, it can still be made adjustable. |

"It is both strong and secure. Use it in anything from heavyweight cables and hawsers to the smallest of cords. It is perhaps the best way to connect two ropes that there is. It's absolutely secure and jerk-resistant in all materials and is perfectly symmetric. It's also remarkably easy to untie after use, even when wet." (ref)
"After the war, I left the Navy and began sailing on merchant ships. In the past 30 years I've visited just about every deepwater port in the world. Knots are my hobby. I've read every book on knots that I could find and I've never seen the Rosendahl bend in any of them. It's as If it has been forgotten along with the airship . . . and that's a shame, because it's the most useful knot I know for tying two lines together. It's especially good for towing, mooring, or anchor lines, where a heavy strain can jam an ordinary knot and make it almost impossible to untie." (ref)
"Yup, it's the Zeppelin bend. Seriously, this really _is_ the only knot (ok, bend) I know that will hold in shock cord. It's true that you can tighten up a square knot to the point where it will probably hold, but you'd never be able to undo
it again even with dental picks and pliers. Cinched up moderately tight, the Zeppelin will hold perfectly, but you can still untie it for another use and/or to adjust the tension in the shock cord." (ref)
"Inflator hose retainer (short length of shock-cord looped under D-ring on left cheststrap to keep the hose in front). The knot tied in this loop when it left the Halcyon factory worked itself undone after three dives - they _didn't_ use a Zeppelin bend!" (ref)
"Also, I encourage everyone to take a look at The Zeppelin bend. It's the simplest, strongest, most elegant, most useful knot I've ever seen. It'll take you fifteen seconds to learn it, and then you'll forever know the best way to tie ropes together." (ref)
"If you can remember "b over q" then you can tie a Zeppelin in less than five seconds - faster with practice. The only competition here is the Alpine Butterfly Bend, but that wastes more length, is slower to tie, and harder to remember. Other contenders are significantly less strong (Fisherman's) or waste much more rope (Double Dragon). It's arguable that the Ashley Bend is as good as the Zep, but I think the Ashley would be harder to tie in the dark." (ref)
"Use bungee for the pocket contents, your compass, and wrist-mount computer. It might be worth your while to replace the bungee on your inflator hose, too. On mine, the original knot from the manufacturer kept falling apart under stress, so I replaced it using a Zeppelin Bend (see link above). The new knot still shows no signs of slippage." (ref)
"One of my favourite knots. I use it to tie leather thongs for medallions and whatnot. Has never failed in the corrosive conditions of my neck." (ref)
"According to Budworth, "This is probably the best of a whole trustworthy family of symmetrical bends comprising two interlocked overhand knots. It works even in big stiff hawsers and cables and is suitable for everything from hobbies to heavy industrial use. ... The knot does not have to be completely tightened before loading; it is secure even with daylight showing through it (fig. 4)." (The Complete Book of Knots, p.44)" (ref)
"I've used the zeppelin bend for pulling cars. You make a loop through
the two rings attatched to each car and tie with the bend. And what
amazes people is it can be rolled out even after being put under so much
strain. It also pulls itself together which helps if it is tied
loosely. Tim Kerby" (ref)
"Invented in the 1930īs by Commander Charles Rosendahl to secure the U.S. Airship Los Angeles. It resists snagging, and is fairly simple to tie and untie. It may be the best way to connect two ropes, absolutely secure and jerk-resistant in all materials, easy to untie after use (even when wet), and perfectly symmetric." (ref)
"But I have to confess disappointment that the ongoing feature on knots didn't mention the Zeppellin Bend - the subject of a rant of mine on this forum a few months ago. I say this only half tongue-in-cheek. The fact that this knot will not slip when tied in shock cord makes it a very useful knot for divers to know."

The water knot can jam pretty badly. I've had good experience with using the Zeppelin knot for stretchy material, and I know many scuba divers have made the Zeppelin knot their first-choice knot for bungee. (Kevin @ roo_two)
In regards to the Ashley Bend, it can sometimes become difficult to untie after serious strain. Many bends have different ways in which they can tighten. The Zeppelin Bend doesn't appear to have a mode of tightening that ever causes jamming. (Kevin @ roo_two)
"We used the Rosendahl bend because of its superiority to the carrick bend, bowline, or sheet bend, all of which are more likely to jam under a heavy load. The Rosendahl distributed the load evenly throughout the knot and could always be untied in a hurry, even after a sudden surge of the Los Angeles had put tons of extra weight and stress on it." (ref)
The sheet bend is the standard way to join two ropes, yet the knot tends to snag things and also tends to flog loose. Enter the Zeppelin Bend. It is a very secure knot; the ends come out perpendicularly, resisting snagging, and it is fairly simple both to tie and untie. Brion Toss (The Rigger's Apprentice) gives the knot very high ratings.

The single most useful knot I've found for rigging gear is the Zeppelin Bend (http://notableknotindex.webs.com/Zeppelin.html). It's ideal for making loops and use with shockcord/bungee. For instance, I used it to Replace the strap on my SK-7 wrist compass with two loops of bungee. Getting the compass on over my drysuit and gauntlets is sooo much easier now, and it's more secure, too.
Secure my inflator hose to the left chest D-ring. The Zeppelin bend seems impervious to the tugging stresses that did in the manufacturer's original knot. Are you listening, Halcyon?
