Saw the photo, and have to say that it is possible to get your kayak under there, but only when she is in an empty state, when laden you would need a submarine, so i don't think it will be a worry.

Great photo form a distance. There's a rather worrying photo on Wikipedia (type Maersk Triple E class) that shows kayakers under the twin-skeg stern. Are there systems in place to prevent potential accidents with other water users? Someone said they have camera's everywhere but when you look at the photo on Wikipedia, I can't visualise camera's being able to see these people at this angle. They're right underneath !!
