Question 2162 Deck Safety

The correct answer is D) be subject to severe racking stresses. A vessel with a large GM (metacentric height) will have a high initial stability, which means it is less likely to capsize. However, this high stability also makes the vessel more susceptible to racking stresses, which can lead to structural damage. Racking stresses occur when the vessel twists or distorts due to the forces of the waves. Vessels with a large GM are less likely to roll heavily in waves, which is why option A is incorrect. While the large GM may reduce the likelihood of cargo shift (option C), it does not necessarily prevent the vessel from shipping water on deck in heavy weather (option B).
