In the publicity photo's of ship landing's the V-22 looks like one prop is
in "ground effect" and the other one is hanging over the side of the ship so

Does anyone know how big of a problem this is? Does it limit the cross-wind
performance? So even though it's vtol the ship has to be pointed into the
wind etc?

It depends on the ship, but the Osprey has to deal with the same sorts
of problems when hovering over buildings on land.

The trick is that the pitch of the two props isn't fixed to be the same
value so it can adjust for uneven lift.
