Vikings primarily powered their boats using sails and oars. Their longships featured a square sail made of wool or linen, which harnessed wind for propulsion during favorable conditions. When the wind was not suitable, crews would row using oars, allowing for greater maneuverability and speed. This combination of sail and oar made Viking ships highly effective for both exploration and warfare.
