The Harlinger Watersportvereniging (HWSV), founded in 1932, operates a well-regarded yacht club and marina on the Van Harinxmakanaal in Harlingen, situated within the town's historic canal network.

The harbour offers a sheltered berth close to Harlingen's city centre, with direct access to the Wadden Sea, IJsselmeer, and inland Friesland waterways.

When exiting the Tsjerk Hiddesluizen lock from seaward, the marina is reached by turning immediately to starboard; from the direction of Franeker, turn to port before the lock.

Visiting boats are welcome alongside the approximately 96 permanent member berths, with around 20 visitor moorings available. The marina is primarily a club facility, and membership is required to be placed on the waiting list for a permanent berth.

Beyond maintaining the harbour, the association organises sailing events, courses, and youth sailing lessons.
