S1, E5: After 450 days at sea the Orient Expedition has already sailed around South America, visited Antarctica, crossed the entire Pacific and arrived in Oceania. The goal of the Schurmann Family on its third sail around the world is to reach Asia where it will investigate the trips of the "Treasure Fleet" between 1405 and 1433, when the Chinese explorers visited thirty-seven countries almost a century of the European explorers. Following its route, Sailing Yacht Kat sails up the coast of Queensland, crosses the Coral Sea and goes towards Papua New Guinea. And wherever it goes, the Schurmann Family interacts with native communities and exchanges memorable experiences. In Gona Bara Bara the family encounters a community going through a water crisis and ends up donating five hundred liters of Sailing Yacht Kat's tanks. In Yanaba they meet a man who in 1993 found a message in a bottle thrown by the family when they passed through the region more than two decades ago and the reuniting is more thant a surprise. Thus, living a new emotion every day, the Schurmann's remain steadfast in their investigation into a little known fact and are surrounded by mysteries that preceded the era of the great discoveries.
