Watersportcentrum De Duikelaar sits at the northernmost tip of the Sloterplas in Amsterdam's Nieuw-West district, and has long been a well-known fixture on the lake.

The center offers rentals and courses for a wide range of water activities, including sailing, canoeing, kayaking, windsurfing, and stand-up paddleboarding, with programs available for both children and adults.

The marina accommodates vessels up to twelve meters in length with a draft of up to 1. 5 meters, and winter dry storage is available for boats up to approximately six meters. By water, the harbor is reachable via the Akersluis (lock no.

102) or the Cramergrachtsluis (lock no. 112), both remotely operated. The site also has event and classroom facilities, making it a versatile hub for watersports in Amsterdam.
