Port Charles Harbor is a full-service marina located on the Mississippi River in St. Charles, Missouri, nestled along Mile Marker 221.5 in the Upper Mississippi River. It serves both local boaters and transient river travelers, providing docking, dry storage, repair, and RV lodging amenities in a scenic and functional river-front setting. From its modest beginnings to its present status, Port Charles Harbor in St. Charles, Missouri, has evolved into a noteworthy hub for river-based recreation and river cruising. The marina traces its origins all the way back to 1928. Over time, it has grown not only in infrastructure but in reputation. Over the decades, Port Charles Harbor developed its amenities in response to both local demand and the needs of transient cruisers.
Its service offerings are comprehensive: full repair and restoration (including hull and woodwork), parts service, winterizing, and more. The harbor also supports campers and RVs, providing riverfront sites with utilities, and features a ship’s store, courtesy car, and on-water towing or fuel delivery. Many boaters emphasize the staff’s helpfulness, prompt response in emergencies, and willingness to handle unexpected repair needs. Port Charles Harbor’s history, facilities, and strategic positioning make it a standout among marinas in the St. Charles /Upper Mississippi River region.
Starting from nearly a century of family operation, to its current ownership, the harbor has matured into a full-service marina catering not only to local boaters but to transients and long-distance cruisers alike. Against the backdrop of other marinas in the area, Port Charles offers a deeper level of service and restoration capability, while maintaining the welcoming attitude and local connection that many marinas lose when they scale up.
One of the key strengths of Port Charles Harbor is the breadth of its amenities. For boats, there are covered wet slips that accommodate vessels between 26 and 60 feet, full utility connections (electric and water), high-speed Wifi, and haul-out / lift services. There are also brand new dry storage racks, traveler-friendly transient slips, and even sites for RVs. On days when slip holders or visitors need provisions, the harbor offers fuel docks with diesel and gasoline, a ship’s store, clean restrooms, showers, and laundry facilities. Another strong aspect of Port Charles Harbor is its repair and maintenance services. Certified technicians work with major marine engine brands such as Mercury, Volvo, Crusader, and Westerbeke. The facility is capable of hull painting, bottom work, fiberglass and wood refinishing, restoration, and full parts service. The presence of a 60-ton travel lift and a 70-ton lift allow for significant haul-out and dry-dock work.
Port Charles Harbor is an exemplary marina for those navigating the Upper Mississippi River waters, combining solid amenities, competent service, and a quiet, riverfront atmosphere. For both locals and cruisers, it offers a reliable haven for docking, repair, and respite. Its strengths lie in its maritime-focus: skilled staff, good facilities, and an emphasis on safety and comfort for boaters
