Which outcome occurred when Viking longship sails experienced perpendicular headwinds?

💡 Explanation

Controlled course deviation upwind occurred because the sail's aerodynamic lift and the keel's resistance to leeway enabled the ship to 'tack' against the wind using aerodynamic lift, therefore enabling navigation, rather than drifting directly downwind.
