Definitely more & more are appearing in the ports. Were you still there at sailaway? and if so did they sounds their horns/whistles or just sail out quietly.
We were in Madeira recently onboard Oriana and her sister ship Azura was in port, as Azura left she sounded her horn several times, but Oriana didn't bother responding which was a real shame.
