Question 1 of 27070

When a vessel is inclined, the tendency for it to return to its original position is caused by the __________.

🔍 Key Concepts

• Transverse stability and what makes a vessel want to “right” itself after being heeled • How center of gravity (G) and center of buoyancy (B) move when the vessel inclines • The role of the righting lever (GZ) and what physically creates it

💭 Think About

• When the ship heels to one side, which point actually moves inside the hull: the center of gravity or the center of buoyancy? Why? • Which change during a small heel creates a horizontal separation between G and B, and how does that separation produce a righting moment? • Look at each option and ask: does this effect create a force couple that tries to bring the vessel back upright, or is it just describing something that happens without necessarily causing the righting tendency?

✅ Before You Answer

• Be clear which point is considered fixed for small angles of heel and which point shifts with the underwater shape • Recall that the righting moment comes from a vertical force (displacement) acting through a point that has moved sideways, creating a lever arm • Check which option directly describes the mechanism that creates the righting lever (GZ), not just a secondary effect like free surface or flotation changes

Question 1 of 27070
