La estabilidad transversal:A vessel’s transverse stability:
Show the answer
Correct answer: b) Is harmed when weights are raised.
Why it is correct
Raising weights on board raises the vessel’s centre of gravity (G) toward the metacentre (M), reducing the metacentric height (GM = KM − KG) and righting lever. Transverse stability is therefore harmed when weights are raised and improved when they are lowered.
Why the others are not
- a) To improve transverse stability, weights must be lowered toward the bilge, not raised.
- c) Vertical weight shifts directly change KG and therefore the metacentric height GM.
- d) Static transverse stability is an intrinsic property of hull geometry and weight distribution.
How to work it out in the exam
- Raising weights raises G, reduces GM and harms transverse stability.
