A ______________ is a single turn and a ______________ __________ is two complete turns around an object.

The phrase "knot, double knot" accurately describes the relationship between the two terms in the context of securing objects using rope or line. A "knot" refers to a single connection made by tying the rope to itself, creating a reliable method of fastening. A "double knot" indicates that two complete turns have been made, providing additional security and stability to the fastening.

In various applications such as boating, climbing, or even in everyday use, understanding the distinction between a simple knot and a double knot is crucial. A double knot typically offers greater strength and reduces the chance of the knot coming undone under load, which is particularly important in high-stakes environments like those encountered in boat operations and rescues.

This terminology contributes to the clarity and effectiveness of communication amongst crew members, ensuring everyone understands the methods being employed to secure gear, lines, or equipment.
