Q

How are the larger sizes of manila line measured?

🔍 Key Concepts

• Traditional ways natural fiber rope (like manila line) are sized on merchant and fishing vessels • The difference between measuring rope by diameter versus circumference • How larger vs smaller rope sizes are commonly specified in deck seamanship

💭 Think About

• Think about how older, natural-fiber ropes are listed in traditional seamanship tables and chandler catalogs—what unit do they usually use? • If you wrapped a tape measure around the outside of the rope instead of straight across it, what measurement would that give you? • Which of these units would be easiest for a deckhand to check quickly on a coil of large manila line?

✅ Before You Answer

• Recall how your seamanship or deck-general textbook labels 3-inch, 4-inch manila line—what is that number actually measuring? • Mentally compare: a 1/2-inch diameter rope vs a 1-1/2 inch [other measure] rope—how are big natural-fiber lines usually described? • Eliminate options that are not standard practice for rope sizing in maritime seamanship (for example, radius is rarely used in rope descriptions).
