Which performance reduction happened to Viking longship sails when repeatedly soaked with seawater?

💡 Explanation

Increased weight causes performance reduction because the additional mass from repeatedly soaked sails increases the ship's displacement and therefore lowers hull speed, rather than affecting drag or maneuverability like warped or stiff sails.
