Which maneuver was impossible for single square-sailed Viking longships due to aerodynamic limits?

💡 Explanation

Longships could not sail directly upwind because 'beating' requires angled sails to generate lift. Sideslip limits their turning; rather than vectoring force forward with a small angle of attack, they lost momentum and could not advance against substantial headwinds therefore making forward progress impossible.
