← HistoryWhich navigational consequence arose when a Viking longship lacked ballast?
A)Substantial reduction in transverse stability✓
B)Complete failure of sail deployment
C)Dangerous keel vibrations amplify rapidly
D)Unanticipated increase in forward speed
💡 Explanation
Reduced ballast diminished the longship's restoring moment. The resulting roll amplification increased the capsize risk because the center of gravity was abnormally high, therefore stability suffered, rather than other issues with speed and vibration from a more rigid keel design.
