In Hear the Ocean Sing, the final volume of Jan Mitchell’s cruising memoirs, she takes the reader to sea with her and husband Ian. Despite experiencing a dismasting, they also wonder at the beauties of the ocean, its creatures and the pristine wildernesses they visit. They sail to remote places most people will never visit, like Bathurst Harbour in Tasmania and Stewart Island in southern New Zealand, showing what can be achieved by ordinary people who have the determination and persistence to follow their dreams. Jan also documents her observations of changes in the oceans over the past forty years. She notes the decline in fish numbers and seabird populations as well as changes in ocean currents, leading to increases in water temperature - all effects of climate change.
