Question 2110 Deck Safety

The correct answer is C) add weight symmetrically below G. To lower the metacentric height (GM) of a vessel with a negative GM, the key is to add weight symmetrically below the vessel's center of gravity (G). This lowers the position of G, which in turn decreases the distance between G and the metacenter (M), thereby reducing the GM. Adding weight symmetrically ensures the vessel's stability and trim are not adversely affected. The other options are incorrect because ballasting on the high side (A) or transferring weight to the high side (D) would further increase the negative GM, and simply deballasting (B) does not address the root cause of the negative GM.
