Chris Dittmar heads out in the Brand New “Big Duck” to see Granite Island and the surrounding Islands off Victor Harbor like never before – from the water. The Big Duck Boat is a 7 metre Gemini - the type used by the Military and SAS, very safe and perfect for Encounter Bay Touring. Fantastic scenery, sheltered beaches, sea lions, dolphins and in winter every chance you could spot a whale during the Big Duck’s hour long tour.
