The static stability curve for a given vessel peaks at 34°. For this ship, what would be the danger angle for a permanent list?

🔍 Key Concepts

• Static stability curve (GZ curve) and what the peak at 34° represents • Relationship between the angle of maximum righting arm and the danger angle for a permanent list • How a permanent list affects the usable range of positive stability on the listed side

💭 Think About

• Think about where on the GZ curve the ship has its greatest ability to right itself and how that relates to when a list becomes unsafe. • Is the danger angle for a permanent list smaller than, equal to, or larger than the angle of maximum righting arm? Why would that be, in terms of safety margin? • If the curve peaks at 34°, what fraction of that angle is commonly used as the practical limit (danger angle) for a permanent list in stability practice?

✅ Before You Answer

• Confirm that the 34° given in the question is the angle of maximum righting arm, not the danger angle itself. • Recall the standard rule-of-thumb: the danger angle for a permanent list is a specific proportion of the angle of maximum GZ, not an arbitrary number. • Before choosing, check which option represents the appropriate fraction of 34° that is normally used as the danger angle in stability problems.
