Rory McGrath, Griff Rhys Jones and Dara O Briain head to the Adriatic to experience the region's amazing maritime history -- travelling by boat of course! Starting with a ride on a military motor yacht that used to be used by the leader of the Socialist Republic of Yugoslavia, they progress to a naval sail training ship dating back to 1931. After a mini cruise boat ride, Dara becomes a local sword dancing expert, and all showcase their non-expertise in a game of cricket against the Germans.
