Which operational risk increased during longship voyages when repeated water saturation weakened hemp rope?

💡 Explanation

Sail luffing or tearing increases because cyclical wetting and drying degrades load-bearing capacity through cellulose breakdown; this is a form of material fatigue. Therefore, sails risk failure under wind load; rather than over-drafting (hull geometry) or crew fatigue (physiological effects).
