← HistoryWhich risk increases when a late 18th-century square-rigged ship is steered sharply to increase its wetted surface?
A)Reduced translational rudder effectiveness
B)Increased hydrodynamic drag
C)Heightened heeling hydrodynamic instability✓
D)Decreased mast structural integrity
💡 Explanation
Heightenened heeling hydrodynamic instability results in because increased wetted surface area generates more wave drag, exaggerating roll. This is the metacentric height phenomena; therefore, ships can capsize easily rather than experiencing purely translational drag increase without heeling risk.
