Jachthaven/-Werf Kats is a rustic tidal marina operated by Van der Rest Nautic, situated directly on the Oosterschelde within Nationaal Park Oosterschelde.

Its tidal location means boaters can come and go without waiting for bridges or locks, and its central position on the Oosterschelde allows sailors to plan routes flexibly around tide, wind, and weather conditions.

The marina offers 140 permanent berths, each with its own side jetty and 10-amp shore power. Additional facilities include winter storage both outdoors and in a frost-free indoor shed of 5,500 m².

The site is noted for its quiet, natural surroundings, making it a popular base for those seeking to explore the broader Oosterschelde waterway.
