This shocking video was shot by a reader of the Dubrovnik Times and shows how not to moor a tender in the Old City of Dubrovnik harbour.

The tender came from one of the cruise ships at anchor between the island of Lokrum and the Old City. With the engine flat out the skipper decided to moor “hand brake turn” style up against one of the stone quays.

Apart from stirring up the Adriatic like a whisker he also managed to create waves that bumped all the smaller local boats at mooring into each other.
