Emily S. Rueb interviews Jean-Jacques Savin, a French adventurer who “spent 127 days alone in a large, barrel-shaped capsule made of plywood, at the mercy of the winds and currents.” It sounds like he had a lovely time:

If it was nice, I swam, and dove underneath the barrel to catch a fish, sea bream, to supplement my meal.

I made a breakfast in the morning, and a nice dinner in the evening. I had a lot of time to write my book. I played a lot of bluegrass on my mandolin.
