South Jersey Marina is situated in Maurice River Township, in southern New Jersey, along the banks of the Maurice River, which flows into the Delaware Bay, an estuary on the Atlantic Coast. This marina serves recreational boaters and sailors navigating the inland waterways and bay areas, offering access to tidal environments for activities like fishing and cruising in the coastal region of Cumberland County. It is positioned in a rural, riverfront setting that connects to broader Atlantic coastal waters.
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.
