"The Bowline is based on an unfinished Slipped Overhand. The Front-Back Bowline is based on an unfinished Slipped Figure 8. The Stevedore Bowline (below) is based on an unfinished Slipped Stevedore."
I admire this kind of thinking. It is precisely this kind of thinking that can lead to solutions and construction.
Unfavorably, the kinds of thinking that I most often encounter tend to foster problems and destruction, so it is very refreshing to experience finally some constructive thinking like this. I admit that I have been somewhat disappointed that the IGKT forum delivers as much destructive thinking as it does.
After I made this Stevedore Bowline, I assessed its properties and started thinking about some things that I usually wouldn't get to think about in other contexts. Then, I acted on those thoughts, in an attempt to see whether I could achieve what I wanted. The important thing is that what I wanted was instigated by this new knot. Had it not been for this new knot, my mind would have been . . . somewhat less active.
The very first time that I made this Stevedore Bowline, I may have dressed it incorrectly, because I found my working end to slip; but, the second time it did not slip. In my opinion, ALL Bowlines should be made stopper flush anyway, so that the slipping of working ends will never need to be a concern. The third time, I made it using 3/8" hollow-braid polypropylene, which is notorious for slipping, and it did not slip.
Then, I made a Front-Back Bowline, contrasted it with the Stevedore Bowline, and saw more constructive thinking! This is how great, new knots can come into existence, as well as how to learn what techniques are effective, what techniques aren't, and what techniques will give a knotter exactly what's wanted.
There are some very subtle yet powerful things waiting to be discovered; most of them are overlooked--owing to the disease of assumption, and the wrong attitudes.
Someone somewhere may view the forum, see your knot, notice something valuable about it, start using it, discover more about it, teach his son, and so on. A knot that you set forth one day may one day be solving a problem in someone's home.
