Callistemon, oh , yes , something like this can be caused by wind. DH is a marine surveyor, worked mainly in the offshore oil industry, but many a marimers tale can he tell of events like this and their causes. There was a tanker that went down in the channel, leaking oil everywhere and he had to go down in a min-submarine to inspect the damage, and the weather suddenly deteriorated and they were trapped there for 24 hours, with the minimum of facilities. I was only told during the event, because there was a fear that the papers had got the story.
