USCG Exam PracticeVessel stability — metacentric height, free surface
A commercial fishing vessel operates north of 42°N but south of 66°30'N latitude during the icing season. Under 46 CFR §28.550, what is the minimum assumed weight of ice per square foot on horizontal projected surfaces?
- A. 6.14 pounds per square foot
- ✓ 3.07 pounds per square footCorrect
- C. 1.54 pounds per square foot
- D. 4.60 pounds per square foot
Why B is correct
46 CFR §28.550(c) requires that vessels operating north of 42°N but south of 66°30'N use one-half the values specified in §28.550(b). The full value for horizontal projected area in §28.550(b)(1) is 6.14 lb/ft², so the reduced value is 3.07 lb/ft².
