In sailing, a "coil" refers to a method of storing ropes (lines) in neat, circular, or spiral loops to prevent tangling, reduce deck clutter, and ensure they run freely when needed. A Flemish coil is a flat, tight spiral on the deck, while standard coiling involves hanging the line, often with the bitter end at the bottom.

Key aspects of coiling include:
Purpose: Keeps lines organized, prevents snagging, reduces wear, and makes the deck "shipshape".

Flemish flake (or Flemish Coil): A decorative, flat, spiral coil laid on the deck, often used for docking lines during short stays.

Flaking/Coiling Method: Involves coiling the line, often with a slight twist in the hand to ensure it lays flat, and sometimes secured with a final wrap.

Storage: Ropes are coiled and hung on cleats or belaying pins to keep them out of the way.

Safety: Proper coiling is essential for quick, tangle-free deployment of lines in emergencies.
