Sven Yrvind, 83 years old, has become a Swedish world celebrity through his solo sailings across the world's oceans. What initially looks like risky adventures on merciless seas is perhaps to an even greater extent an inner journey, which begs the question: How do we really want to lead our lives? In the Viaplay documentary Philosopher of the Sea we get to follow Yrvind during five years of constructing his own boats to sail non-stop from Ireland and New Zealand.
