Wikipedia:
"A rope is a group of yarns, plies, or strands which are twisted or braided together in order to combine them into a larger and stronger form."
""Rope" refers to the manufactured material. Once rope is purposely sized, cut, spliced, or simply assigned a function, the result is referred to as a "line", especially in nautical usage."
Vessels are secured to a pontoon or quay with head and stern ropes. Sails have bolt ropes.
Nautical terminology is not always as exact as some might like.
