Q

When any tank or compartment is partially filled with a liquid free to move as the ship rolls, the free surface effect is present. This condition will usually __________.

🔍 Key Concepts

• Free surface effect in partially filled tanks • How free-moving liquid affects a ship’s center of gravity (G) • Relationship between center of gravity and overall stability

💭 Think About

• When the ship heels, what does the liquid in a slack (partially filled) tank do, and how does that affect the ship’s balance? • Does the free surface effect make the ship more able or less able to return to upright after being heeled? • Which option describes a general, usual effect on the ship’s ability to remain safely upright, rather than a special or extreme case?

✅ Before You Answer

• Focus on the usual, overall effect on the vessel, not a rare or secondary consequence • Ask yourself whether the free surface effect makes the ship safer or less safe in a seaway • Eliminate choices that deal with permanent conditions (like fixed list or trim change) instead of the general dynamic effect when the ship rolls
