Laura's camera proves therapeutic for the onset of loneliness that strikes her early in the expedition; the device is something to talk to. She comments on the silly and mundane, but also on the more profound experiences of being thousands of miles from land or another human. We hear her sniffling through tears as she films a pod of dolphins swimming alongside her boat, pleading with them to stay awhile and assuage her feelings of isolation.

Yet as time and the documentary go on we sense a change in Laura. She's relishing the days on end of alone time, and seemingly more attuned to the fluctuations of the ocean. A rather dicey passage around the southernmost tip of South Africa offers up 60-foot waves and weather conditions that a newspaper informs us "even the bravest skipper wouldn't attempt." Laura checks in with us for a moment during this leg of the journey, glowing green in her camera's night vision, unphased by the torrents of rain and wind raging outside.

Of course many of the most daring parts of Laura's voyage -- those that would consume her undivided attention -- aren't caught on camera, and we're left to fill in the blanks. Director Schlesinger instead focuses on the meditative aspects of the young woman's sail, examining how a preternaturally assured teen handles the day-in, day-out routines of taking care of herself and her home, getting from point A to point B, drifting pleasantly in between, and greeting and parting from new places and friends.

I would argue that Laura's voyage is a coming-of-age, at once grander and more outlandish than most, while set in a strangely contained microcosm of time (two years) and space (her 40-foot boat). Yet Schlesinger also pointedly includes home video and photo montages of Laura's early life as an infant and toddler, when she and her parents, who soon thereafter divorced, were sailing the globe as a family. It's telling that Laura retraces her parents' route port for port, and that she repeatedly refers to the sunny, tropical locations as"paradise." As she describes in voiceover her difficult childhood, much of which she spent alone while her single father worked and her mother began a new, separate life, we realize that Laura's record-breaking sail not only represents her ascension into adulthood, but also her way to reclaim a paradise lost.
