No motors, no support, all the way to Alaska.

That’s the terrifying tagline for the Race to Alaska, one of the most grueling sailing races in the world. It’s a treacherous enough journey to deter even the world’s most experience sailors.

Hard Ship—part of a collaboration between Great Big Story and CNN Films—tells the harrowing story of three paralyzed men determined to complete the Race to Alaska, despite their physical limitations.

The Great Big Films team was embedded with the crew for its entire journey. Hard Ship is the second of twelve Really Great Big Stories, a year-long celebration of storytelling and documentary film.
