When fishing with my four boys the "Improved Cinch" is the easiest for us to tie. The others look simple but are hard to tie due to the stiffness of the line. We put the line in the eye of the hook, pinch the two strands and rotate the hook about six times. Then we put the end of the line though the eye end loop, the big loop and snug it up. The knot does not come undone. The hook often gets snagged and we break the line.

The picture should show a big loop at the hook eye to put the end of the line through. The picture makes it look hard.

We are novices and only fish from the shore, just like your survivors.
