During the great age of sail in the mid-1800s, wooden-hulled schooners rounded the rocky tip of the Marblehead Peninsula as they traveled to and from the busy Port of Sandusky Bay, carrying limestone and lime, fish, apples, nails, and many other goods that could be shipped in barrels. Until 1870, the Marblehead Lighthouse was known as the Sandusky Bay Light. By the early 1900s, steamboats had replaced the schooners, but the lighthouse remained an important navigational aid for decades. More recently, the Sandusky port has been used to load coal from southeast Ohio railcars onto Great Lakes vessels. Modern electronic navigational aids have greatly reduced the lighthouse’s importance for commercial shipping, but it still serves as an important visual reference for the many pleasure craft in this popular resort area and warns boaters away from the rocks, as it has done for nearly two centuries. Facing east, Cedar Point is visible opposite Mosely Channel, a north-south shipping route for lake freighters traveling to and from port in Sandusky Bay about six miles to the south.
