Boats are a marvel. A human invention, mastered over thousands of years to provide food, travel and commerce to the ever evolving need of modern man. Boats are fun. They’re buoyant excuses for rich people to drink champagne, wear white floppy hats and have poor people serve them oysters. But boats are scary. There’s only a layer of wood and fiberglass keeping you from drowning, getting eaten by a sea creature and keeping you from catching hypothermia. And boats are traumatic. The slightest thing can go wrong and if you survive, will be left with a lifetime of mental anguish and trauma and maybe even some survivors guilt. Slate’s final episode of an elongated Season 7 will cover all of these topics, but mostly the traumatic ones in an episode he coined BOATSASTER.
