Sam, I found them through the internet. They are called Enterprise Marine and it looks like they charter out of several locations. I picked the Waukegan location as it is closer to my home. I suspect we will visit one of the following sites since I am only OW certified.
Schooners 20 ft. (Zion) - Unidentified wooden schooners. Good shallow dive in a sheltered location.
George Morley 20 ft. (Evanston) - 200 ft. wooden steamer that burned on December 9, 1907. Wreck has intact hull below the gunwales.
Seabird 30 ft. (Great Lakes) - 190 ft. sidewheel steamer that caught fire and sank on April 9, 1868. Huge paddle wheel, 26 ft. in diameter, with cast iron axle is reasonably intact.
Wells Burt 30 ft. (Evanston) - 201 ft. bulk carrier sunk in a storm on May 21, 1883. 2/3 of the wreck's deck remains in place and is easily accessible through the hatches. Deck equipment, including capstan, windlass and chain brake are present.
Kate Kelly 40 ft. (Racine) - 126 ft. two masted, wooden schooner that sunk during a storm on May 14, 1895. Wreck is broken in two.
Winds of the Wind 40 ft. (Chicago) - 142 ft. two masted schooner which sunk after being struck amidship by another vessel on May 12, 1866. Intact bow, bow sprit, large wooden windlass on deck, and centerboard truck are present.
Lady Elgin 55 ft. (Fort Sheridan) - The "Titanic" of the Great Lakes. On September 8, 1860, the 'Lady Elgin', a 252 ft wooden, sidewheel passenger steamer, with 393 passengers on board, was rammed by a lumber laden schooner. Only 98 passengers survived this terrifying disaster. Remains of the ship are located in 3 primary areas.
