[tuatoru]

Truncated-pyramid floating wind turbines shouldn't have as much of a problem with this, as the loads are closer to traditional transverse and axial.

(Picture two flat-topped letter 'A's, one behind the other, with a crossbar going from the top of the front one to the top of the back one. The blades spin around this crossbar, an axle. The generator can be at one end of this axle, or in the blade hub. The whole structure is floating, moored at one corner, and can rotate to keep the blades facing into the wind as required.)
