🔍 Key Concepts

• Deck cargo securing terminology used in seamanship and cargo handling • Difference between supporting a load and securing a load • How wooden blocks or dunnage are used under heavy items on deck or in holds

💭 Think About

• Which choice best describes a method of supporting and distributing the weight of a deck load rather than tying it down or packaging it? • Look at the materials mentioned (wood, chains, cardboard, crate). For which one is the main purpose to build up a stable base or framework under the cargo? • In seamanship, when would you need to build a temporary structure or stack of blocks to raise or support something heavy?

✅ Before You Answer

• Verify which option describes wooden blocking used to build up a base or support, not to wrap or tie cargo • Check that the option you pick is about under or between cargo and a surface to spread the load and keep it steady • Eliminate any choices that mainly describe fastening gear (like chains/shackles) or packaging (like crates/cardboard) rather than support blocking
