The term short-sea shipping comes up aplenty these days, as the powers-that-be rediscover the practicalities and the economies of waterborne transport. The thinking is renewed and the interest revitalized, but for a lot of harbors nationwide it's deja vu. Take the island city of New York, and the multitudes of communities near and far that are joined to it by inland waters—the rivers, sounds, creeks, streams—all the way up to Albany, to Waterford and the Canal system, and to everything beyond that. There's nothing new about the short-sea shipping principle around here.
