Question 1820 Deck Safety

The correct answer is D) curves of minimal operational metacentric height for the vessel. The SOLAS (Safety of Life at Sea) Convention requires that the master be provided with information to obtain accurate guidance on the stability of the vessel under varying conditions of service. Specifically, the vessel must have information on the minimum operational metacentric height (GM) that ensures adequate stability for the vessel. This is a key parameter for the master to understand and operate the vessel safely. The other options are incorrect because they do not directly relate to the stability information required to be provided to the master under SOLAS. Option A deals with speed and rolling, option B is about vertical center of gravity, and option C is about the inclining test procedure, none of which are the specific stability information that SOLAS mandates be provided to the master.
