🔍 Key Concepts
• Shipboard cargo handling equipment and how it’s classified
• Different parts of steering and maneuvering systems (steering engine, rudder, bow thruster)
• Terminology used for rigging, derricks, and cargo handling gear
💭 Think About
• Group the four choices into two categories: which are related to ship maneuvering, and which are related to lifting or handling cargo?
• Ask yourself where you are most likely to see or hear the term "contra-guide": in the wheelhouse/engine room, or out on deck near masts, booms, or cranes?
• Consider whether a "contra-" (meaning "against" or "opposite") guide would more logically be something that opposes/controls motion of a load, or something that directly turns or pushes the ship.
✅ Before You Answer
• Make sure you can define steering engine, bow thruster, and rudder well enough to rule out what a "contra-guide" is NOT.
• Recall that many specialized terms ending in "-guy" or "-guide" are associated with rigging and cargo handling gear, not with hull or propulsion machinery.
• Before choosing, picture the term in a sentence like: "Rig up the ______ before starting cargo operations" or "Check the ______ before getting underway" and see which context fits best.
