Which outcome was amplified in Viking longship voyaging when sailcloth material aged disproportionately across its surface?

💡 Explanation

Uneven sail degradation caused differential drag, resulting in translational *center of effort displacement*, because force vectors became asymmetrical. Therefore, ships experienced directional instability rather than efficient power transfer, since twist was induced.
