Jachthaven Havenkwartier Blauwestad is a modern city marina situated on the southern shore of the Oldambtmeer, in the heart of the Blauwestad residential area of the same name.

Founded in 2013, it offers permanent berths in box sizes of 7, 10, and 12 meters, along with visitor moorings totaling around 150 berths overall.

The marina serves as one of the main access points to the Oldambtmeer and includes a wide trailer ramp for launching boats.

On-site facilities include sanitary amenities, electrical hookups, drinking water, a waste water pump-out station, and camper van berths. A waterfront restaurant and a public sandy beach are located nearby.

The marina is a popular starting point for exploring the broader network of waterways connecting to Groningen, Friesland, and Drenthe.
