Safety & Environmental Protection (Deck) USCG Question #2681 (Set 81)

A cargo of 40 tons is to be lifted with a boom located 40 feet from the ship's centerline. The ship's displacement including the suspended cargo is 8,000 tons and the GM is 2 feet with cargo suspended. What will the list of the vessel be with the cargo suspended?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 5.7°

Suspended weights act as if their entire mass is located at the point of suspension (boom tip). The heeling moment equals weight times outreach. Dividing by displacement (8,000 tons) and GM (2 feet) provides the tangent of the list, resulting in 5.7 degrees.
