Question 1 of 27070

Q

If a vessel lists to port, the center of buoyancy will __________.

🔍 Key Concepts

• Center of buoyancy (B) is the geometric center of the underwater volume of the vessel • When a vessel lists, the underwater shape changes and so does the position of B • Relationship between heel/list direction and where the underwater volume shifts

💭 Think About

• Picture the ship upright: where is the underwater volume centered, and where is B located? • Now imagine the ship slowly listing to port: which side (port or starboard) gains more underwater volume? • As the underwater volume changes side-to-side, in which direction must the center of buoyancy shift to stay at the center of that volume?

✅ Before You Answer

• Identify which side (port or starboard) is deeper in the water when the vessel lists to port • Determine on which side the underwater volume is now greater • Remember: B must always be at the center of the immersed (underwater) volume, not above, not below it
