On May 7, 1965, Cedarville was travelling between Rogers City, Michigan and Gary, Indiana with a load of of limestone. east of the Mackinac Bridge, in heavy fog, Cedarville collided with the Norwegian ship MV Topdalsfjord. The collision occurred as a result of miscommunication between the two ships, which both changed their course a mile away from each other, with Topdalsfjords captain steering his ship on a course that would lead to the two vessels passing each other on their starboard sides. The captain of Cedarville, however, intended for his vessel to cross the bow of Topdalsfjord, but his message stating such was not received by Topdalsfjord, which continued on a course that led to it colliding with Cedarvilles port side. While the collision caused only superficial damage above the waterline, consisting mainly of broken railings and deck plates, the bow of Topdalsfjord had created a large hole in Cedarvilles hull below the waterline, and within minutes of the collision a slight list to the port had developed. The captain of Cedarville ordered water to be pumped into the starboard ballast tanks to counteract the list, and intended to try to run the ship aground to prevent it from sinking. As the ship moved towards land, however, the weight of the water within the hull forced the bow down, and the ship began listing to starboard, eventually rolling over before sinking. Most survivors of the collision, in which ten out of the 35 aboard died, were picked up by the German freighter MV Weissenburg, and subsequently transferred to the US Coast Guard cutterMackinaw.
A U.S. Coast Guard inquiry into the incident found that the captain of Cedarville was at fault for the sinking and was charged with four counts of faulty seamanship. He initially pleaded innocent, but in August 1965 changed his plea to guilty. His license was suspended for a year as a result of the inquiry.
Wreck site
The wreck of Cedarville lies in the Straits of Mackinac Shipwreck Preserve in water around deep, although the highest point of the hull is around below the surface and the cabins of the ship are around underwater. Expert divers are able to enter the ship, as most parts remain fairly undamaged. Cedarville is the fourth largest ship lost on the Great Lakes after, and sister ship Carl D. Bradley.
