2017 World Open Water Swimming Offering of the Year Nomination

The Channel of Bones is a documentary film by Silverline Productions of Toni Enderli’s crossing of the Molokai (Ka’iwi) Channel in Hawaii that took an agonizing 20 hour 35 minute. From his dramatic finishing on Sandy Beach on Oahu to his interactions with escort pilot Ivan Shigaki and crew members Linda Kaiser and Andrew Mitchell, the film is riveting with the suspense that builds as the coastline never seems to get closer. For highlighting the challenges faced when, where and how to start the 42 km inter-island crossing, for showing the beauty of a tropical location known for its big, bad, blue waters, for sharing the difficulties faced by swimmers, pilots and crew in a marine adventure that can go south at any moment, The Channel of Bones documentary is a worthy nominee for the 2017 World Open Water Swimming Offering of the Year.
