Actually, to quote one of my physics professor's t-shirts: "Science doesn't suck!
Airfoils, either wings or sails, generate lift. It would be more accurate to say that they are pushed, than sucked. The is a high/ambient pressure on the windward side of the sail attempts to move into the low pressure zone on the leeward side the sail is pushed forward.
Sorry, sometimes my physicist side and my sailor side get crossed.
