Also known as: Georgiana III
12 mi. E of Kenosha, Lake Michigan, Wisconsin



The luxury diesel yacht Rosinco (U.S. #214160) was 95 feet 2-1/2 inches in length and built in Wilmington, Delaware by Harlan and Hollingsworth. She was built as the Georgiana III and the ship changed hands twice before becoming the Rosinco.

She rests at the bottom of Lake Michigan in 185 feet of water, about 12 miles east of Kenosha. The Rosinco is marked with a buoy during the diving season. She is mostly intact, stands upright and is remarkably well preserved.
