AMERICA is in the midst of a revival of interest in things nautical—nineteenth-century nautical. It began with the efforts of a handful of romantics to preserve the few remnants of the age of sail and was intensified by the magnificent Bicentennial Operation Sail. Now seaports across the country—in New York and San Diego, Philadelphia and Galveston, San Francisco, Boston, and Houston- are turning their waterfronts into public parks, often with a tall windship as the centerpiece. Such acts of urban renewal and historic preservation are praiseworthy and even stirring but they are happening only because of the irony that our historic ports are being abandoned by modern shipping.
