🔍 Key Concepts
• Ship construction terminology for openings in the shell plating (like ports, hatches, doors)
• Differences between structural members (beams, bulkheads, stays) and securing/closing appliances
• How cargo ports, sidelights, and shell doors are held in place or reinforced
💭 Think About
• Which option describes something that is specifically associated with holding or securing an opening in the ship’s side, rather than just adding general strength?
• Look at each choice and ask: is this mainly a load‑carrying structural member (part of the ship’s framework), or is it a device/bar used to close or secure something?
• In cargo operations, when you have an opening in the side shell for cargo handling, what kind of simple mechanical device would you expect to see to keep it closed in heavy weather?
✅ Before You Answer
• Identify which choice is connected to a shell opening or port rather than general framing
• Separate options that are primary structure (beams, bulkheads, stays) from those that sound like securing hardware
• Make sure the option you pick could realistically be removed or swung out of the way when the opening is in use
