Which primary outcome forced early Viking longships downwind?

💡 Explanation

Excessive leeway occurred because Viking longships mainly used square sails, inducing significant sideways drift with crosswinds. This limits maneuverability; therefore going downwind was easiest rather than tacking into wind, as narrower hulls didn't help.
