Medium-sized marina with covered slips along a river, adjacent to a surface parking lot with several vehicles and surrounded by industrial buildings.
Marquis Small Boat Harbor Marina is situated in Rock Island County, Illinois, along the Mississippi River in the Quad Cities region, which is characterized by its riverfront landscape featuring urban areas, bridges, and natural bluffs, rather than the Great Lakes. This marina primarily serves recreational boaters and sailors who navigate the Mississippi River for activities such as cruising, fishing, and exploring the river's extensive waterways and locks. It is located in a historically significant area where the river forms a natural border between Illinois and Iowa, offering access to the Upper Mississippi River's diverse ecosystems and commercial traffic.
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.
