🔍 Key Concepts

• Lifeline requirements for life floats and buoyant apparatus in 46 CFR (inspect the detailed construction requirements) • The difference between material requirements (diameter, buoyancy) and arrangement requirements (bights, festooning) • How USCG rules often handle an option like "unless the line is an inherently buoyant material"

💭 Think About

• Look at each option and ask: is this an actual phrase or structure you might see in 46 CFR wording for lifesaving appliances? • Consider whether the regulations tend to specify exact numbers (like diameter and bight length) and whether those numbers here look realistic and consistent with each other. • Think about how a lifeline is intended to function in the water: what features help people hold on, and what features prevent the line from sinking or tangling?

✅ Before You Answer

• Verify in 46 CFR whether 3/8-inch minimum diameter is the specified size for lifelines on life floats/buoyant apparatus. • Check if the regulations explicitly require seine floats in each bight unless the line itself floats. • Confirm whether the rules mention festooned bights not longer than three feet and whether all three conditions are grouped together in one requirement.
