TopSide Marinas Acquires Rathbun Lake Marina

TopSide Marinas, a family-owned company that acquires and operates high-quality marinas throughout the United States, has recently acquired Rathbun Lake Marina, a full-service marina and resort destination located on Rathbun Lake in Moravia, Iowa. The acquisition strengthens TopSide’s growing footprint in the Midwest and marks its entry into the Iowa market.

The 160-acre leasehold property with the U.S. Army Corps of Engineers features approximately 246 wet slips, boat rentals, four campgrounds with roughly 144 campsites and a 12-room hotel. Guests can also enjoy on-site dining at Louie’s Lakeside Bistro and Barbecue, a seasonal, independently operated restaurant open from April 15 through October 15 that is accessible by boat, camper or car. Established in 2010, Rathbun Lake Marina offers other outdoor, resort-style amenities like a soccer field, frisbee golf and other family-friendly activities.

TopSide Marinas plans to invest in several enhancements, including expanding capacity with an increased total slip count, adding roofs to uncovered docks, and introducing a service department. To accommodate additional public boat launches, the boat rental operation and parking area will both be expanded.

This first Iowa marina follows the company’s February 2026 entry into Michigan with the acquisition of Bay Harbor Marina. TopSide Marinas also owns and operates marinas across the country including Hideaway Marina, Cape Fair Marina  and Campbell Point Marina in Missouri; Galveston Yacht Marina, North Point Marina and April Plaza Marina in Texas;  Beavers Bend Marina in Oklahoma; Rock Creek Marina in Kansas; Bay Marine of Sturgeon Bay and Pikes Bay Marina in Wisconsin;  and, Larsen Marine and Bay Marine of Chicago in Illinois.
