Jachthaven De Knar is a marina located directly on the waterway near the aquaduct between the Wolderwijd and the Veluwemeer, close to the city of Harderwijk.

The harbor was completely rebuilt and reopened in 2015 following a major relocation to its current position along the main sailing route. It is home to watersports association W. V. Flevo.

The marina welcomes visiting boaters during the sailing season and offers modern facilities including electricity and water at the docks, as well as shower and toilet facilities in the clubhouse "De Kop van de Knar" and additional restrooms in the harbor office.

From the marina, the center of Harderwijk and the Dolfinarium are reachable by bicycle within minutes.
