Uses:
The double half hitch is commonly used to tie a line to a post or
dock eye. The knot can slip apart under high stress loads so it
should NOT be used for "mission-critical" things like
tying a rode to an anchor.
Efficiency: 65-75%
Instructions:1) After coming around the post, make an underhand
loop (the loop goes under the standing part - attached or long
end of the line.) 2) Bring the bitter
end (free end) up over the standing part and through the eye
which you created. 3) Next make a second underhand
loop around the standing part, and run the bitter end through
this eye. 4) Tighten the hitch.
Notes: You know you have it correct when the bitter
end is in the inside of the loop.
