When did the ferry stop going to Cedar Point?
I contacted Annie Zelm, a spokeswoman for Cedar Point. She sent me the following answer to your question:
The demand for ferry services to Cedar Point diminished over the last century, beginning with the opening of the Cedar Point Chaussee in 1914. In 1952, Cedar Point ended regular steamer service by taking the G.A. Boeckling out of commission and moving it to Sturgeon Bay, Wis., where it became a floating warehouse. The Cedar Point Causeway opened on June 12, 1957, making the peninsula more accessible for vehicles.
After retiring the Boeckling, Cedar Point operated three ferries until 1987, when the park leased them out to the City of Sandusky Boat Line. The boat line later purchased the ferries and ran them from downtown Sandusky to Cedar Point until 1997, when the operators of the boat line sold the entire operation because it was no longer profitable. Ridership had been declining for years, and it was no longer economically viable.
The following year, Cedar Point began running the Harbour Belle ferry from the park to the Radisson Hotel, which is now Castaway Bay. That operation lasted only a few years and ended because it was too costly to continue.
