Watersportcentrum De Zeilhoek is a small, quiet marina situated on the Gouwzee near Monnickendam, with a direct open connection to the Markermeer — no bridges or locks to navigate.

The marina offers 159 berths with shore power, accommodating sailing yachts, motor yachts, and catamarans, including vessels up to 30 meters in length, with larger spaces available at the ends of the jetties. Visitor berths are also available.

The facility is well equipped for recreational boaters, with drinking water, showers, waste pump-out, WiFi, a mast crane, and a restaurant on site.

A sheltered grassy area with children's play equipment, a sun terrace, BBQ areas, an outdoor kitchen, and free use of SUPs and open sailing dinghies round out the amenities.

The center of Monnickendam — with shops, restaurants, and bicycle and canoe rentals — is just a short ride away, and Amsterdam is reachable in roughly 20 minutes by car or public transport.
