Q

Which action reduces the yawing of a vessel in a following sea?

🔍 Key Concepts

• Yawing in a following sea and how the bow vs. stern behaves when waves come from astern • Effect of weight distribution (trim) on directional stability • Difference between GM (metacentric height) and longitudinal trim effects

💭 Think About

• When waves come from astern, which part of the ship tends to be lifted and pushed around first, and how does that affect heading? • How does moving weight forward or aft change the ship’s trim and the way the bow “bites” into the water? • Does increasing GM mainly affect rolling, or does it directly control yawing in a following sea?

✅ Before You Answer

• Identify which options change trim (fore-and-aft balance) versus which change transverse stability (GM) • Think about which trim condition makes the bow more ‘grippy’ and directional in the water instead of being easily swung by the stern • Verify in stability notes: in a following sea, what trim is recommended to improve course-keeping and reduce yawing/broaching?
