In a boat, is it true that the higher the centre of mass, the slower the vessel's rolling ability? Thanks for any help in advance.

On the contrary, the higher the center of mass above the water-line, the more easily she will tip over (heel), especially if she happens to be a sail boat. The speed at which the boat returns to even keep (her quickness), depends upon how the mass is distributed around the center of mass and not location of the center of gravity per se.
