Now imagine reproducing those voyages in modern times, aboard the same open boats. That’s some of what Thor Heyerdahl’s legendary voyage of Kon-Tiki in 1947 was all about — proving that major ocean crossings could be done in period craft. Me, I get seasick easily, so I’d rather hurl around a race track at 200 mph than set off on an ocean voyage. But I deeply admire the Pacific Voyager fleet. In seven replicas of the ancient sailing vakas, each carrying a crew of 14 to 16 people from more than a dozen island nations (including Fiji, New Zealand, the Cook Islands, Samoa, Vanuatu, Hawaii and Tonga), they set off from New Zealand in April and arrived in California, where they are now, in early August.
