Wide vs narrow blades (was: New study on wind energy)

So by that logic, a sailing ship would be propelled faster
(capture more wind energy) by having a small sail vs a large sail.
But a sail *does* have lift. Note that drag is a function of V^3.
Is that your way of saying "yes, a smaller sail would propel a given
ship faster than a large sail" ?
If that's not what you're trying to say, then please explain.
