The book is dedicated to an amazing man, a navigator who twice circumnavigated the earth alone on small boats, Evgeniy Aleksandrovich Gvozdev. This book should have been and wanted to be written by the sea traveler himself. That way it would be fuller and more interesting. But Evgeny Gvozdev died during his third solo circumnavigation of the world, so the story about his sporting and scientific feat is based on letters and telegrams to the author and materials from many friendly conversations before and after circumnavigation.
