Uncharted shipwreck near Duluth remains a puzzle

Excerpt:

Scuba diver Yan Saillard on Thursday explored the wreck, which sits in about 10 feet of water, 150 feet from the Duluth shore.

"It looks like a tugboat, about 50 to 60 feet long, with a 3- to 4-foot diameter propeller," Saillard said, adding that he didn't see any markings that would help identify the former craft
