I can't imagine leaving the rig up... we get some high winds in the winter. A Santa Ana (offshore) condition (which is normal in fall through January) can bring 30 kt plus offshore at the blink of an eye. We were thinking the mast foil alone was going to be an issue for them. The last hard wing boats down here were tipped on their sides at night on a huge hydraulic rack. That isn't happening with this 90 footer. I suspect they will learn to use the gin pole a bit quicker over time and bring the rig down.
I've always heard that a hard wing, properely feathered and allowed to weathervane on a mooring, is actually quite stable in very high winds...more so than a bare mast. The wing should dramatically reduce the wind turbulence.
