Note on Time and Mapping

Salvador Alvarenga kept track of time using the cycles of the moon. He was always clear as to how many months he had been adrift. The chronology in this book is a combination of his memory, studies of ocean currents and documents provided by search-and-rescue officials. Special thanks to Nikolai Maximenko and Jan Hafner at the University of Hawaii and Art Allen of the US Coast Guard for their generous work to re-create Alvarenga’s voyage.
