← HistoryDuring a Viking longship voyage, which outcome results when sailcloth permeability dramatically increases?
A)Reduced vessel speed and control✓
B)Increased hull structural stress
C)Enhanced rudder response time
D)Improved crew weathering protection
💡 Explanation
Sailcloth relies on aerodynamic efficiency; increased permeability causes pressure equalization across its surface because boundary layer separation reduces lift forces. Therefore, the vessel slows and loses maneuverability, rather than increasing hull stress or improving rudder response due to differential pressure changes.
