Mystery Ship Marina is situated in Menominee, Michigan, along the western shore of the Upper Peninsula, where the Menominee River meets Green Bay, an arm of Lake Michigan in the Great Lakes region. This marina serves recreational boating and sailing activities on the freshwater expanses of Lake Michigan, catering to boaters exploring the area's scenic waterways and nearby islands. Its location provides access to both protected riverine waters and the open lake, making it ideal for a variety of Great Lakes boating pursuits.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
