Question 1 of 27070

Which term describes the time required to incline the vessel from port to starboard and back to port again?

🔍 Key Concepts

• Roll period vs. stability – how fast a ship rocks in calm water compared to how stable it is overall • Difference between initial stability (GM) and dynamic ship motion terms • Meaning of inclining moment during a stability test vs. the observed ship motion at sea

💭 Think About

• Ask yourself: which term is specifically about a time interval for one complete side‑to‑side oscillation? • Which option names something you measure in seconds, rather than something you measure in degrees of heel or ton‑feet of moment? • Which of these terms is commonly used when timing how quickly a vessel feels "stiff" (snappy) or "tender" (slow) in a seaway?

✅ Before You Answer

• Identify which choice refers to a time-based measurement (seconds) rather than an angle or distance of heel. • Recall that initial stability (GM) and range of stability are properties of the righting arm curve, not a timing of motion. • Remember that an inclining moment is a heeling action applied during a stability test, not the time it takes the vessel to respond.
