Which risk increases when poorly-cured hemp ropes used in a Viking longship's rigging experience repeated wetting and drying?

💡 Explanation

Strand galling risk increases because without proper curing, the hemp fibers degrade and lose lubrication therefore rope fibers abrade each other under strain, rather than slide smoothly. Torsional fatigue, biofouling, and static friction are not primary risks related to poor curing.
