Marine: rope vs line
Self-tutoring about marine terms: the tutor mentions the difference between rope and line.
The following is by my understanding.
In yard work context, one might think of rope. However, to a mariner, a rope ceases to be so when it’s fastened to a spot for a purpose; it then becomes a line.
Therefore, to a mariner, a coil of rope sitting on a shelf might indeed be rope. However, if one end of said coil is fastened to the frame of the boat in preparation to moor the boat to the dock by its other end, the coil becomes a line.
