Extreme weather events in Mediterranean mid-July 2014

In July 2014, the Adriatic, Ionian, and Aegean seas saw cold mid-level sea currents meet warm surface sea temperatures (24–26C). This combination, along with the absence of wind shear, is favourable for producing waterspouts (a tornado of water moving across the surface of the sea).

According to Wikipedia, waterspouts vary in strength and may pose a threat to vessels that encounter them.

Pertinent to our investigation are eyewitness reports of a waterspout which formed over the Ionian sea (see map here: https://goo.gl/maps/3vK7jQ7dVcQ2), which falls roughly within the region in which we believe the Ghost Boat was sailing.
