Sven Yrvind is willing to pay a big price for some alone time.

The Swedish sailor wants to cruise non-stop around the world by himself in a sailboat slightly larger than a bathtub.

“I’ll be completely safe. It’s like a ping-pong ball in the sea, it never breaks,” Yrvind said while showing the boat in his workshop.

“A small boat constructed the right way is always stronger than a big boat.”
