ALGONAC (WWJ/AP) – A long-distance swimmer who calls himself “The Shark” is making his way across Lake St. Clair in a 30-hour, 22-mile dip — hauling dinghies filled with 2,000 pounds of bricks.

Jim Dreyer, 49, began his latest swim Monday from a spot near Algonac, and hoped to finish Tuesday at Detroit’s Belle Isle.

And he’s doing it without a support boat.

Four hours into his swim, and Dreyer was still going strong.

One of the dinghies is equipped with a radar target so Dreyer will show up on radar screens of passing freighters. He has to feed himself and won’t leave the water until coming ashore in Detroit.

Dreyer has a pretty good track record — having in the past made direct crossings of each of the five Great Lakes.

With his Lake St. Clair trek, he’s trying to raise money and awareness for Habitat for Humanity.
