Cruise ships in the Santorini caldera

Santorini is a very popular cruise ship destination in Greece/the Mediterranean. The ships stay out in the caldera by keeping their position with their engines and side thrusters.
The time-lapse shows the caldera over one day with 3 cruise ships doing their "dance" while the guests are being ferried to and from the island in small boats.
The caldera is also crisscrossed by other charter and tourist vessels as well as island ferries (which have their harbor towards the top left corner).
I left my camera on our hotel balcony and let it run for the whole day. The day was very hazy and cloudy with very high humidity, hence the very muted colors/cool colors.
