What is the best loop knot in the end of a line?

Surgeon’s Loop ranks first (strong field fit, 79%). Level with Perfection Loop on weighted field fit (Strong). It is printed first on a faster retie (instant against fast) — not because it fits better

And with cold, wet hands?

Surgeon’s Loop still ranks first.

And with wind and boat motion?

Surgeon’s Loop still ranks first.

And with retied all day?

Surgeon’s Loop still ranks first.

And with first time tying it?

Perfection Loop moves to first (81%).

Best loop knot in the end of a line

A fixed loop that doesn't slip, for loop-to-loop connections or hanging a rig. The loop has to stay the size you tied it.

Why it wins

·Level with Perfection Loop on weighted field fit (Strong). It is printed first on a faster retie (instant against fast) — not because it fits better
·End loop that is tied quickly
·Cold hands
·Strong connection-job fit (86)

Watch for

!Seated on the standing line alone, leaving the tag side loose so the tag pulls back inside
!Tag trimmed before the knot fully closed, leaving it loose
!Strands of the double crossed over each other inside the knot

Pick Perfection Loop instead Surgeon’s Loop leads on retie speed (95 vs 84) and field tieability (85 vs 78). Perfection Loop still holds an edge on connection-job fit and finished profile.

How sure this is

Low confidence: this question states only a few conditions, or the top knot's strength figure isn't traceable to a published test. Add your own conditions in Decide to sharpen it.

51 of 61 modelled connections were ruled out by hard constraints before anything was ranked. A knot that fails a constraint is never scored, however strong it is elsewhere.
