New Haven Marinas is excited to announce the growth of yet another premium marina to our management portfolio:  Grafton Harbor Marina!   This is a premier waterfront destination at one of the most iconic confluences of American waterways—the Mississippi River and the Illinois River, just north of St. Louis.

This represents a major step forward in our expansion along the American Great Loop, marking our second property along this legendary boating route and bringing our management portfolio to eight marinas across five states. Grafton Harbor’s pristine condition, ideal location, and strong tourism draw make it an outstanding addition to the New Haven Marinas family.

A Premier Destination at the “Key West of the Midwest”

Nicknamed the “Key West of the Midwest,” Grafton is known for its vibrant riverfront culture, thriving tourism market, and unbeatable sunsets. The marina is ideally situated on the Illinois–Missouri border—offering direct access to two major U.S. waterways and serving as a key stopover for Great Loop boaters, regional visitors, and outdoor enthusiasts.

Surrounded by attractions—including local wineries, a bustling casino district, scenic bluffs, and year-round recreation—Grafton Harbor Marina stands out as one of the most desirable boating destinations in the region.
