With new programs on luxury ships, you can learn the lindy hop or quit smoking while circling the globe.

It used to be that to learn to meditate, you had to go to an ashram; to study a language, you had to go back to school. With the latest curricula aboard "smart ships," those days are history. Beyond the obvious libraries and fitness classes, passengers can now learn to appreciate wines with noted vintners, expand their cooking repertoire with respected chefs, practice their poses with yogis, and even master a language with a native speaker—all while sailing around the world.

Cunard's long-anticipated Queen Mary 2 will be the ultimate smart ship when it makes its maiden voyage in January 2004, with the only sailing planetarium, five university-at-sea classrooms, a 20,000-square-foot spa operated by Canyon Ranch, and not one but two celebrity chefs—Daniel Boulud as consultant and Todd English with his own restaurant. In the meantime, here are the most inventive and intensive self-improvement programs afloat. Find an itinerary and set sail on an enriching excursion.
