“Viking longships used a large square sail combined with oars for propulsion.”
The evidence strongly supports this description of Viking longships. Archaeological finds, ship reconstructions, museum research, and standard reference works all indicate that longships were propelled by both oars and a large square sail. The lack of surviving sail fabric affects fine details of sail construction, not the core conclusion.
“Viking ships had shallow draughts that allowed them to navigate up narrow rivers and to be beached directly on coastlines for surprise attacks.”
The evidence strongly supports this description of Viking longships. Authoritative museum, archaeological, and reference sources consistently state that their shallow draught and light construction let them travel in shallow water, move up rivers, and be beached directly for rapid landings, which helped make raids more sudden and flexible.
