🔍 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.
