🔍 Key Concepts

• Lifeboat falls construction requirements in 46 CFR Part 160/199 (lifesaving equipment) • Differences in flexibility and strength between 6×7, 6×19, 6×24, and 6×37 wire rope constructions • Why regular-lay, filler wire, and core type (fiber vs wire) matter for lifeboat handling gear

💭 Think About

• Which construction is most commonly specified for lifeboat falls that must run freely over sheaves, be flexible enough to handle, but still strong and durable? • Look at each choice: which one is more suited for standing rigging (stiff, few wires) and which is for running rigging (more flexible, more wires)? • How does a fiber core vs an independent wire-rope core affect crushing resistance and durability in a lifeboat winch drum?

✅ Before You Answer

• Verify which wire-rope construction (6×7, 6×19, 6×24, 6×37) is standard for running gear like falls, not for standing rigging. • Check which option specifies regular-lay filler wire – this is often associated with lifeboat falls in USCG/IMO guidance. • Confirm whether a fiber core is normally accepted for lifeboat falls or if a wire core is preferred/required for strength and resistance to crushing.
