double bowline?

[Alyosha]

Someone mentioned a "double bowline" (apparently abbreviated DBBB) in another thread. Dr. Flash Amazing had even posted a link, but the link was broken.

 

Would someone please post a link/picture of the "DBBB" that isn't broken? Alternatively, if you think you can explain in text how to tie the "DBBB" to someone who knows how to tie a regular bowline and a bowline-on-a-bight, that'd work too.

 

I googled for "DBBB bowline" and found nothing besides this thread. So, I googled for "double bowline" , and the most promising-looking thing I found was this:

 

double bowline page

 

But I thought double bowline, as shown on that page was weaker than the figure-eight (because the rope makes a sharper bend)? Or is the "DBBB" the "Water Bowline" or the "Zeppelin Loop"?

 

Thanks

the figure eight and double bowline are essentially the same strength. that is they weaken a rope to about the same extent (like arond to 75% of original strength). the single bowline will weaken a rope to about 60% of original strength.

you will find many different knots labeled bowline. just like how the 'bowline-on-a-bight' you know is probably a french bowline. the link you gave works for me to describe a 'double bowline'.

Curiously, Climbing seems to have removed this extremely handy Tech Tip from their website.

 

Fortunately for you, the intrepid Dr. Flash Amazing has braved the vicissitudes of the interweb to bring you the goods, apparently pirated by someone in China.

 

And now, for your edification, "the goods":

 

 

The "a, b, c, d, e" on the diagram is the order in which you should tighten the loops on the knot to get it properly dressed. This knot rocks, by the way, and hasn't broken yet!

Neat, thank you. I feel edufied.

I think bowlines may be the most confusing section of the knot worlds nomencalture... like lummox said.

 

This is what I would calll a double bowline:

A friend of mine showed me this real cool knot that he ties in with. Its really cool. I'm going to use it all the time now. Its called the Flemish Bend, has anybody heard of it before?

[snoboy]

It would be intersting to know how you tie in with a bend...

that looks like a french bowline. some climbers call it a bowline on a bight though it really isnt. the bowline on a bight would have two strands making the 'rabbits hole'. the seascouts f-ed it up. there is even nomenclature for which way the rabbit goes around the tree.

it is kina funny that the coast guard tests on shit like bowlines but they are hardly ever used on a boat. the really bitchin bends are so weird to tie when under pressure of time and bad weather thats when the bowline comes out: weakest link.

I always thought this was a double bowline too. At any rate, I like it cause it makes a nice seat to sit in and also a loop to go around your waist so you can't fall out when you need to rescue somebody or something.

[Thinker]

I'd call that a bowline on a coil.

Here's a primer on the French Bowline ...

 

of course, the context for use is a slightly different 'sport.'

[Dr_Flash_Amazing]

To clarify, DFA's example was the famous/infamous "DBBB" (double bowline with a bowline backup), by the way. To add to the confusion, the "bowline with the 'Yosemite finish'" is also popular for similar low-bulk, easy-untie (when you want to!) reasons.

i have been toled by wrongheaded people that this is a double bowline too (and a bowline bend):

this is about the weakest way to join two ropes and i also been told it is wrong. a perpetuated myth. the real non-weak way to do it is to make the rabbit hole with one rope and use the other rope end as the rabbit. then do the opposite to finish it. then it is one of the strongest ways to join two ropes.

bowline craziness in the middle of the night.

you mean a surgeon's knot?

[lummox]

you mean a surgeon's knot?

aarrggh! my head hurts. i thought a surgeons knot was a lot like a granny but with another twist.

anyway. check out the middle 'bend' on the right:

way strong way to join two ropes. i seen it called 'double bowline'. i would never use it climbing cuz the knot could roll.

gotchya... yeah that would be kinda sketch.
