It is a book about the adventures of a young man - a beachcomber -on board of one or more ? clippers, while sailing around the world. A fascinating adventure book. I have read this book as a boy around 1940.
In 1945 this book had been set on the index of not tolerated books in the soviet zone, and foolishly as a 13years old boy have discarded it. The reason might have be some non respectful passages about 'non white' races, preposterous nowadays!
