Imagine the kind of girl who goes kayaking in an open ocean populated with flesh-eating alien fish things. And by open ocean, we mean that the entire planet is under water except for this one cluster of islands near the equator. So if she gets lost out there, there are no landmarks to help her find the way back - it's just an endless stretch of ocean from here to the horizon to the end of the world.
Oh, yeah, and she doesn't believe in using a compass. And don't worry about her getting eaten - she'd been reinforced with a titanium-alloy skeletal reinforcement and polymerized dermal weave armor. Actually, you might want to worry about the flesh-eating alien fish things.
