Heeeey @madlenfox, I know this Yatch, it's the "Mar sem Fim". It's not related to the story on this book, nor it is Amyr Klink's boat, they only share the same name.

This boat on the picture belongs to a brazilian guy named João Lara, the boat was crushed by ice compression, if you search on youtube by "mar sem fim boat" you'll find some of the journeys they did.
