• Characteristics of chain lashings vs web straps/wire
• How shock loads, corners, and weight affect securing gear
💭 Think About
• For each option, ask yourself: In real life, what practical problems can this cause when securing and handling chains on deck?
• Think about what happens to a chain link when it bends tightly around a sharp edge or corner under high tension.
• Consider how a rigid securing device behaves in heavy seas compared to something slightly elastic.
✅ Before You Answer
• For each statement (A, B, C), decide if it describes a real, practical disadvantage of chain lashing on heavy vehicles.
• Ask: Does this factor make chain lashings less safe, harder to handle, or less efficient on a Ro-Ro deck?
• Before choosing D, make sure every single individual statement (A, B, and C) is truly correct in practice.
