What is the term for a flat line that is coiled around in circles?

The term that refers to a flat line that is coiled around in circles is "flemished." Flemishing is a method used in rope management where the line is laid down flat in a circular shape on the deck. This technique is important because it helps to organize the line, prevent tangles, and make it easily accessible for use when needed. The flemished coil keeps the line neat and can reduce friction and wear on the rope by minimizing sharp bends or kinks.

Other terms like "laid," "spliced," and "twisted" refer to different processes or arrangements of rope. For example, "laid" involves the method of constructing a rope by twisting together individual strands, "spliced" refers to joining two pieces of rope together by intertwining them, and "twisted" generally describes how rope is constructed through torsion. These terms do not accurately describe the specific organization of a flat line coiled in circles.
