USCG Exam PracticeVessel stability — metacentric height, free surface
Under 46 CFR §28.545, when a vessel lifts a weight over the side, the angle of intersection of the heeling arm curve and the righting arm curve must not exceed which value?
- A. 25° (0.44 radians)
- B. 15° (0.26 radians)
- ✓ 10° (0.17 radians)Correct
- D. 30° (0.52 radians)
Why C is correct
46 CFR §28.545(c) states that the angle of intersection of the heeling arm curve resulting from the lifting moment and the righting arm curve must not be at an angle of more than 10° (0.17 radians). This limits the static angle of heel under the lifting load.
