Barra takes a sailing lesson up the Lough and encounters a few hairy moments at the helm. He meets Garry Crothers, who sailed from the Caribbean back home on his own, a remarkable feat for anyone, but made all the more impressive given Garry only has one arm after an accident. With his sailing skills honed, Barra joins a punt race in some tricky weather conditions and realises there is no such thing as plain sailing! He searches for shark on the Lough before landing back onshore and tasting some of the local stout made with oysters from the Foyle.
