corkline

noun

1. The top line of a gillnet, which has attached floats (often, but not always, made of cork) that give that edge of the net buoyancy.

   “Double corklines, one right-hand lay and one left-hand lay to prevent twisting, were used on all gill nets.”

   “The porpoise safety panel shall consist of small mesh webbing not to exceed ¼" stretch mesh extending downward from the corkline and the base of the porpoise apron to a minimum depth equivalent to two strips of 100 meshes of 4¼" stretch mesh webbing.”

   “The hold was empty, without a net, corkline, leadline or buoy to be found.”
