摘要：	The term "tugboat" doesn't come close to describing the 60'×28'×10'6" Seaway Trident. It looks like a tugboat, maritime publications label it a tugboat, and its designer refers to it as a tugboat. But the primary focus is not maneuvering vessels in or out of a crowded harbor, though it will do that. Its main duties include scraping ice off the walls of locks and maintaining aids to navigation. The Seaway Trident, powered by a pair of 660-hp Caterpillar C-18s turning Schottel SRP 210 Z-drives, was designed by Glosten, with offices in Seattle and Providence, R.I., and built by Washburn & Doughty, East Boothbay, Maine, for the Great Lakes St. Lawrence Seaway Development Corp., an agency of the U.S. Department of Transportation. As the company name implies, the Seaway Trident works along the St. Lawrence Seaway. "Primarily it's stationed between the Snell Lock and the Eisenhower Lock," said Peter Soles, who works in marine operations and business development at Glosten's Seattle office. That's a narrow part of the St. Lawrence Seaway on the U.S. side. "They call it the pond. I think it ices up pretty hard." The Seaway Trident's major role is keeping the St. Lawrence Seaway navigable by maintaining the locks and the aids to navigation, which requires a lot of winter ice work. For that, the Seaway Trident often will join with the larger Seaway Guardian (118'×l7.5'). The Seaway Guardian breaks up ice jams while the Seaway Trident pushes the ice to the side of the channel, thus keeping the passage clear. It also herds ice into a lock chamber, allowing the ice to flow down river.
