Main Pier Marina is located in the Oscoda/Au Sable area. It is located at the south end of Oscoda, right at the mouth of the Au Sable River. We have easy access, and slips, located on the river, and the state launch shares our driveway. Our marina works together with a Board of Directors to help ensure the marina stays up to date and has a voice in our community. Our annual dues help maintain our boardwalk, and other community areas of the marina. All slips are considered your property and will be purchased complete with property tax documentation.
