Hello,
Saw a vid of russian boys training knots in a marine type school, and I really enjoyed the way they used their arms and body to tie knots - they really got into it 
So I worked a bit with the bowline, cuz it’s one of my favourites and found a very quick method of tying it.
It a bit more ‘physical’ than when I normally tie knots, but should also leave little room for error once you get the movements. And it’s rather quick, I recon a little over 1 second to tie it.
On a side note, I actually saw a few ‘fast way of tying the bowline’ vids on youtube, however several of them are tying the perfection loop by swinging the rope around it self and it’s certainly not the bowline.
Anyway, have a look:
