Watersportvereniging Maas en Waal is a member-run sailing and boating club situated on the north bank of the Maas, just east of the A73 motorway bridge in the floodplain near the village of Heumen.

The harbor has been in operation since the late 1960s and accommodates more than 80 vessels on the water, roughly three-quarters of them sailboats, along with a few smaller craft ashore. The association has approximately a hundred members.

Visiting boaters are welcome during the season, which runs from 1 April to 1 November — a window set by the risks of high and low water outside those months. The clubhouse is open throughout the day, with restroom and shower facilities on site.

The harbourmaster can be reached at 06-19273922; overnight guests are asked to call ahead.
