W. S. V. Loowaard is a small members' sailing club and marina located in the gemeente Duiven, near the area known as Loo or Loowaard, on the Pannerdenskanaal.

The association has been active since 1970 in what was originally a sand-extraction area, with members taking over management of the marina in 1980. The harbor offers 27 berths for members, with unoccupied berths available to visiting boaters.

Water and electricity are available at the pier, and depths at the dock run approximately 2–3 meters. The marina is accessible only by water, on foot, or by bicycle; car access is restricted to members.

A slipway is present on site but is reserved for maintenance of the club's pontoons and cannot be used to launch private boats.
