Best knot to tie a boat to a cleat

A dock line on a horn cleat has to hold through wind and wake and still come off fast when you leave. Most of the method is the turns, not the finish.

Ranks first

Cleat Hitch

Strong field fit · 79% · 29 ruled out first

Why it wins

  • ·Casts off under surge when the lock is one clean hitch
  • ·The job you will tie every trip
  • ·Strong connection-job fit (100)
  • ·29 knots were ruled out before ranking even started (Round Turn & Two Half Hitches, Clove Hitch, Anchor Bend…)

Watch for

  • !Several locking hitches stacked, so the turns jam under load
  • !A full extra round turn on the base, which can clamp down and jam
  • !Too few figure-eights for the load, so the line creeps

What changes the answer

The same question with one condition added. Each row is its own engine run.

How sure this is

Moderate confidence: the order is sound, but the top few are close enough that your own conditions can reorder them.

29 of 30 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.
