Maybe a similar thing happened at Katakolon last year. My Bavaria was stored on the harbour wall and untouched but yachts metres away were toppled.
Seems these "tornados" are very localised, more like twisters in the USA than the cyclones we get here in Australia that have a wide front, many kilometres.
But they are vicious little buggers! No doubt there will be keel, rudder and mast damage everywhere.
