Yes, bare poles in a storm or at when away from the boat at anchor.
A wing needs to be able to be feathered AND also lowered.
Just how often it actually gets lowered at sea will be something we learn as time on type clocks up a bit more...
Perhaps we'd learn to feel safe with a wingmast with a "foolproof" bearing system to feather at the jetty or a fore and aft locking position for a mooring.
For me this may be a moot point if I can get the wingsails sorted well, as they would use circular masts.
