The two classifications for lines in the Coast Guard are which?

• A. Length and Color
• B. Material and Size
• C. Weight and Age
• D. Diameter and Type

Answer: (B)

Lines are classified by material and size. Material tells you what the line is made from (natural fibers like manila or synthetic fibers like nylon, polyester, or polypropylene). This affects how strong it is, how much it stretches, how it behaves when wet or in sun, and how durable it is over time. Size refers to the line’s diameter (or circumference), which determines its breaking strength and what hardware it will fit, such as cleats, thimbles, or winches. Knowing both material and size lets you pick a line that can safely handle the load and operate effectively in the environment, rather than relying on appearance, weight, age, or vague “type.”
