are a sort of tackles fastened to the clues, or lower corners of the main-fail or fore-fail, to truss them up to the yard as occasion requires, which is usually termed cluing up the sails.

CLUE-LINES are for the same purpose as clue-garnets; only that the latter are confined to the courses, whereas the former are common to all the square sails. See these ropes as represented in the article SHIP.
