Braidline rope with a braid core can be coiled clockwise or anti-clockwise, but three-strand line is only happy if it is turning ‘with the sun’, or clockwise. This is to do with the construction of the lay of the rope. To force it anti-clockwise creates excessive kinks. You may get away with it on a short length, but it’s bad practice. Try it on a schooner’s 200ft peak halyard and you’ll be sorry when the mate finds out it was you who caused the sail to jam half-way down!
