The National Geographic channel is running a documentary about Andrew McAuley's ill-fated attempt to kayak solo from Australia to New Zealand in January, 2007 called Solo: Lost at Sea. He was attmpting to paddle 1600 km across the Tasman Sea. 29 days after he set out, 80 km from completing his voyage, he broadcast a distress call. The next day, his empty kayak was found floating within sight of land. His body was never found.
The trailer for this documentary is one the most heart-wrenching pieces of film I've ever seen.
