Everyone is a sailor when the wind comes up. Some good, some bad. Lack of a sail doesn't stop the wind from moving your boat. Get out in a canoe on a windy day and check it out. If your canoe is symmetrical and trimmed evenly, you'll be blown sideways across the waves. Give it a rudder or skeg (mounted or in hand), and you'll be blown mostly downwind with the waves. With a good amount of rocker or dead-rise to the stems, it will be less likely to dig in and broach. These things make for a more survivable ride, even - or especially - without propulsion.
