I'm afraid I know very little about sails, so my frame of reference is limited. Please educate me if you feel so inclined
Welcome to Sailnet.
Just to clarify a bit more, none of these sails/rigs can sail "into the wind". In sailor-speak, "into the wind" generally refers to the direction that the wind is coming from. Any of these rigs will stall out and lose power when turned "into the wind", and the boat will come to a stop.
Modern sails/rigs do allow us to sail "upwind", but usually not closer than within about 40-45 degrees of the wind's true direction. We don't see junk rigs used much nowadays, primarily because modern bermuda/marconi rigs offer better "windward" performance, i.e. they let us sail closer to the direction the wind is coming from.
