- Q131 - Deck Safety: Stability Problems
238. Your vessel is preparing to lift a weight of 30 tons with a boom whose head is 30 feet from the ship's centerline. The ship's displacement not including the weight lifted is 8,790 tons. KM is 21.5 ft, KG is 20.5 ft. What would be the angle of list when the weight is lifted?
The list angle is calculated using the formula tan θ = (w x d) / (Δ x GM), which results in an angle of approximately 5.8 when the given weight, distance, displacement, and GM are substituted.
