Flettner rotor on a boat - ie. magnus effect

Can the vertical rotor create lift?

a curve balls 'laces' exaggerate and bend the magnus effect.
can you replicate this effect on a rotor?
--perhaps to enable another direction of force-- up
optimally I would like to gain lift -to the vertical -reduce downforce
I understand Kutta–Joukowski as it applies to a cylinder.

horizontal rotor?--unknown omidirectional sailing efficiency
ground effect used as a factor?

my purpose for asking is ;where to put the rotor?
a conventional sail creates lift, so is mounted nearer the bow

I;m afraid, if the rotor becomes overpowered, it will drive the bow(s) under

Yes, lift is the aerodynamic force component perpendicular to the free-stream flow.
