The becket bend is the most efficient way of making two short dock lines into one long one.
An eye splice in the end of one dock line is the bight for the becket bend.
Complete the bend by threading the other line up through the eye, around the back of the eye, and back under itself, the same as you would for a sheet bend.
Use this same procedure to attach a line to a metal hook, in which case you’d call it a becket hitch. The hook is the bight.
