The Ocean's Unanswered Questions

On April 15, 2007, a three-man crew set out from Queensland, Australia on a 32-foot yacht called the Kaz II for what was supposed to be a recreational sailing trip. Three days later, a helicopter spotted the boat drifting 88 miles off the Australian coast. When investigators boarded, they found food laid out on plates, a laptop still running, the engine on, and all life jackets still hung up. The GPS and distress functions were working but had never been activated. The only thing amiss was a badly shredded sail and a fishing lure hooked into a side rope. The three men had simply vanished. The coroner's official theory—that one man fell overboard while retrieving his fishing hook, the second jumped in to save him but forgot to turn off the engine, and the third was knocked off by a swinging sail—reads like slapstick. But no bodies were ever found.

This is the kind of story that Wendigoon, a YouTube creator who admits to suffering from "immense thalassophobia," finds most terrifying. For Halloween, he chose not to talk about demons or horror movies but about what he calls "the one thing that truly deeply terrifies me": the ocean itself. His fear isn't of sharks or drowning but of "the infinite depths" and the "fear of the unknown" that the ocean represents.
