Looks like a sailing convoy to me.

Anyways, I was just checking out the site which says what ships will come to Rotterdam and I just saw that ALL the cruises of the MS Rotterdam are gone! There were like 15 trips to Rotterdam and now that is all gone.

So this means that the Ryndam (on Sunday) and Queen Elizabeth (30 August) are the last cruisecalls for this year.
