Nolleke Sas is a quiet marina situated on the river Mark in Noord-Brabant, between Zevenbergen and Standdaarbuiten.

The watersportvereniging was founded in 1970, and the name honors the old lock keeper — a reference to a historic sluice complex that once stood on this site.

That small sea lock, built around 1730, was at one point one of the oldest surviving sea locks in the Netherlands, and the Mark at that time still experienced tidal movement. The marina offers 56 permanent berths along with space for visiting boaters.

The surrounding area is well suited to leisurely cycling and walking. The location on the Mark also makes it a convenient access point for recreational boating on the river.
