Watersportvereniging Oosterland is a small sailing and watersports club situated on the shores of the Brielse Meer in South Holland.

The club supports a range of activities including rowing, canoeing, sailing, and surfing, and its marina features a boat ramp alongside fixed moorings.

There are approximately 48 permanent berths and a limited number of visitor moorings available, with a water depth of around 2. 6 metres. No fuel is available on site.

While the club does not maintain dedicated visitor berths as a rule, passing boaters can often find a spot.

The historic fortified town of Brielle lies within easy reach by foot or by boat, making the location a convenient base for exploring the surrounding area.
