Article: Phillida Eves and her husband Tedd Hamilton weren't unhappy living in the Galway countryside with their sons, Cian and Oisin, and their daughter, Soracha. "We had a lovely home , a car, lots of friends, and weekends sailing our boat", says Phillida. "But there's a line from a poem that goes: 'Tell me, what is it you plan to do with your one wild and precious life?' That says it all for me. We felt that there was more to life." So they quit their jobs, took their sons, then aged six and nine, out of school and went to southern Spain where they bought a 15-meter yacht and headed up the coast to Barcelona. Soracah was not even three. And they brought along Poppy, the family dog. Now, two and a half years and 10,000 km later, they don't intend to stop. Tedd is a yacht engineer and can find work in ports. But, says Phillida, a supply teacher , "Any family could do this". The children are home-schooled using a correspondence course . My son had a recent project on the weather. The weather is vital to us. My son knows more than most adults about weather systems, compasses, maps and directions. The weather, for him, means life or death. Other subjects have become equally vivid. "They're living geography and history all the time. We've sailed round Italy, Sardinia, Sicily, and seen tiny islands we didn't know. The kids learned about ancient Romans by visiting Rome. One summer off the Italian coast we sailed past a volcano at 2am. We woke the kids. There it was, under the moon, with fire coming out the top--you don't get that in a textbook." But what about social development? Again, Phillida is _ . "The children have become much more socially confident since we set out. They play with tones of families of all nationalities on other boats we meet." Living for the moment, they believe, is a huge life lesson. "Our children never say they're bored." The other day they stopped mid-ocean and the kids swam, 110km from land. "That's the kind of freedom we want for them," says Phillida. "That's the kind of freedom they've got."
