Which risk dramatically increased when Viking longships used hemp ropes weakened by persistent saltwater exposure?

💡 Explanation

Sail rigging failures spiked because rope degradation reduces tensile strength due to hydrolysis weakening the fiber bonds, therefore sails were less stable, rather than affecting oar power or hull directly as the catenery mechanism failed under common sail dynamics.
