Allround Watersport Meerwijck is a full-service marina situated on the edge of the Zuidlaardermeer in the province of Groningen, run by the Stalman family since the harbor was built in 1974.

Set within a natural area, it offers more than 300 berths for permanent and visiting boaters, along with a boat lift rated to 25 tons, a fuel station, trailer ramp, electricity and water at most jetties, and a large watersports shop.

The marina serves as a practical access point to the Zuidlaardermeer and the wider waterways of Groningen. The surrounding nature is notably rich — beavers, otters, spoonbills, kingfishers, and rare terns have all been spotted from the docks.

The site also includes camper pitches, making it a base for both water-based and land-based exploration of the area.
