Deck General · Weight Shifts & List
A weight of 10 tons is shifted 15 feet to starboard across a vessel displacing 1,000 tons. What is the listing moment produced?
- A15 foot-tons to starboard
- B150 foot-tons to starboard✓ Correct
- C10,000 foot-tons to starboard
- D1,500 foot-tons to port
Explanation
Listing moment = weight shifted x distance = 10 x 15 = 150 foot-tons to starboard. G shifts toward the moved weight. The resulting list angle depends on GM: tan(list) = listing moment / (displacement x GM).
