Castaway?

A man harvests opihi off the coast of the Big Island of Hawaii.This lonesome individual, scrambling over a tiny islet, searching for food, appears to be the quintessential castaway. But he’s really collecting opihi and the islet is about a hundred-foot swim to the much larger Big Island.

On a different day with windier conditions, the swim wouldn’t be necessary since the surf could pick a person up and slam them against the cliff with no effort required on their part.
