Concerns on Kef for the four occupants of a little motorboat hired out yesterday and not returned. Coast guard and private boats have searched the sea area around Argostoli, where the boat was hired, but have found nothing significant. According to some reports, the hirer used Croatian ID documentation but this has turned out to be a forgery. From what I can make out, this is a little putt-putt motorboat, not powerful enough (or comfortable enough) to get any great distance.
