← HistoryWhich challenge increases for Viking longships during winter voyages?
A)Sail icing and freeze fractures✓
B)Hull damage from cavitation
C)Metal fatigue on oar locks
D)Crew exposure to thermal radiation
💡 Explanation
Sail icing is significant because the added weight and stiffness drastically alter the Aerodynamic profile, therefore sails become prone to rapid freeze fractures and tearing under increased loads because of ice crystal lattices; rather than thermal radiation or fatigue which operate on different scales.
