Final answer:
As the mast tilts, the Center of Gravity (CG) or Center of Combined Gravity (CCG) generally shifts laterally away from the ship's centerline towards the direction of the tilt. The specific movement and correction process involves complex factors, including the ship's weight distribution and the nature of the grounding.
Step-by-step explanation:
When discussing the stability of a ship, the concept of Center of Gravity (CG) and Center of Buoyancy (CB) are essential. When a ship runs aground and tilts, as depicted in Figure 10.36, the Center of Gravity (CG) or sometimes referred to as Center of Combined Gravity (CCG), may shift. Typically, as the mast tilts, the CG or CCG moves laterally away from its original central position. If the ship tilts toward the port side, the CG or CCG will shift toward the port side, and likewise toward the starboard side if the tilt is in that direction.
However, the actual movement of the CG or CCG and the required torque to correct the tilt will depend on several factors including the weight distribution of the ship and the point at which the vessel has run aground. In practice, returning a tilted vessel to an upright position may require redistribution of the cargo, ballasting, or external forces applied through salvage operations.
