One of Eastport’s travel attractions is the “Old Sow,” the world’s second biggest whirlpool or the biggest one in the Western Hemisphere.

Before you make reservations to come see it, let me point out a few things.
- Its intensity varies greatly, depending on the gravitational tides cycle. It’s best about three hours before high tide, especially around the new and full moons when 40 billion cubic feet of water flood through the half-mile-wide passage to Passamaquoddy Bay.
- Its swirling diameter can reach 250 feet or drop 12 feet into its vortex, but it’s also likely to appear as a series of boiling countercurrent piglets and eddies.
- Most of the time, it’s not particularly visible from land. It is, however, a regular feature on Butch Harris’ whale watch runs. And even then, it will likely be a disappointment if you’re expecting to see a big hole in the water.
- It remains, nonetheless, a hazard to small boaters and has claimed lives, most notably in 1835 when a mother watched from shore as a two-masted schooner was sucked down with her two sons. The young men were never seen again.
- Another account, from the late 1800s, tells of two men with a barge loaded with logs, that went under and the bodies never found.
- It’s closer to Deer Island, New Brunswick, than Eastport, Maine, in part a consequence of public works construction of a causeway to the north during the Great Depression that pushed the current eastward.
- The name likely derives from the mispronunciation of “sough” as “sow” rather than “suff,” reflecting a “sucking noise” or “drain.” Or even “grunting.”
- The phenomenon arises from a unique funneling of powerful currents over a sharp trench on the seafloor, with water rising abruptly from 400 feet to 119 feet. It then intersects other trenches to thicken the action.
- The upswell brings nutrients and small sea creatures from the depths to the surface.
- The channel’s ferocious currents can run six to seven knots, a special hazard for divers as well as small boats.
