Modern replicas of viking ships can indeed sail to windward. I forget
exactly how well but they definitely can do it. That the originals
were sailed in this fashion is indicated by the fittings on the hull
to enable them to haul the sail into an almost fore and aft position.
They had no reason to do this unless they were sailing into the wind.
