Deck General · Weight Shifts & List
A vessel is floating at an even keel. A 100-ton weight is shifted from the centerline to 10 feet to port. The vessel displaces 5,000 tons and has a GM of 2 feet. The list angle is approximately:
- A5.7 degrees to port✓ Correct
- B0.1 degrees to port
- C28.6 degrees to port
- D1 degree to port
Explanation
G shifts = (100 x 10) / 5000 = 0.2 feet to port. tan(list) = G shift / GM = 0.2 / 2 = 0.1. arctan(0.1) ≈ 5.7 degrees. The vessel lists to port (toward the shifted weight).
