🔍 Key Concepts

• Static vs. dynamic inclining causes (slow, progressive vs. sudden change) • Effect of weight shift or free-surface on trim (forward/aft) and list (port/starboard) • Relationship between ballast/mud/drill string and how/where their weight acts on the rig

💭 Think About

• Which option would cause a slow, gradually increasing inclination rather than a sudden one? • For a port and forward inclination, where must weight be moving or added/removed: high or low, port or starboard, forward or aft? • Which system on board can quietly and continuously move a significant amount of weight without being immediately obvious on deck?

✅ Before You Answer

• Identify which choices would likely give a sudden change versus a gradual one • Check which option can affect both list and trim in the directions given (port AND forward) • Consider which tank or system is located low in the hull and can transfer large amounts of liquid weight over time
