I was referring to floating platforms which can also be used to support wavebob or other water turbines - which would dampen the yaw of the platform - with the above surface element used to support a wind turbine.  I'm not suggesting trying to balance production at a platform level - merely suggesting that if you have a floating platform already built, you might as well use it both above and below the waterline. Of course you may be right in suggesting a mixed load of wind and wave stresses could require a stronger platform that would be more expensive to build.
