Another basic mariner’s knot, the round turn with two half hitches is simple to tie, easy to learn and holds fast in most situations.
Use it to temporarily fasten a line to a spar, ring or bitt, or in the central hole of a hollow-base cleat.
The round turn starting this knot is better than a simple turn because it resists slipping and distributes contact over two turns rather than one, reducing stress and abrasion on the rope.
Take two complete turns around a spar or ring.
Apply two half hitches on the working part. (First half hitch)
(Second half hitch)
After tying, slip the knot tightly against the object. For a more permanent application, seize, or bind together, the bitter end against the working part.
