For who is interested on sailing, I recommend all the books written by Amyr Klink. He describes in a beautiful and poetic way his journeys across the seven seas. It’s very interesting when he describes the day he faced a 4 hundred meters iceberg (this is just 10% of it’s real size) that traveled oposite to the wind, on his direction. The iceberg follows the sea currents, it does’t care about the wind direction.
