Most teenagers live in flats or houses, but right now Sonia Ruiz is waking up somewhere in the Pacific Ocean because her home is a 20-metre boat. She has %BLANK% over half her life sailing with her mother and father who are both scientists. Sonia's unusual way of life means she regularly sees whales and gets to swim with dolphins, and made friends all over the world. She does her schoolwork online and her studies are going well. Life on board, though, is sometimes uncomfortable. Space is limited, so there are no wide-screen TVs or soft sofas. Bad weather that lasts for days is common, particularly in winter. Storms atsea can be frightening, although modern boat equipment usually helps sailors avoid them.
