Kevin and Jayne Whelan have just completed a circumnavigation, taking their son James (13) and daughter Alexis (5) on a world trip leaving Sydney in 2011, taking in the Barrier Reef, Indonesia, Christmas Island, Cocos Keeling Islands, Mauritius, La Reunion, Africa, St Helena, Spain and more, through the Panama Canal across the Pacific and back to Sydney. After that, 628 nautical miles will be a picnic, but a rough one.
