Which navigational risk increased for Medieval longships traversing open water?

💡 Explanation

Hogging increased the likelihood of hull failure because of a type of longitudinal bending which caused the ship's ends to deflect upwards, rather than sagging, therefore the center would bear loads poorly; more so considering their length and hull construction methods.
