Jachthaven Lockhorst is a family-run marina in Warmond that has operated since 1942, when grandfather Maarten Versluijs dug the initial basin by hand and began renting wooden rowboats.

Now in its third generation, the marina sits on the Warmonder Leede with a direct connection to the Kagerplassen via the Groote Sloot, and easy onward navigation to Leiden. The marina offers around 50 permanent berths and a depth of approximately 1. 70 m.

Services include winter storage ashore and under cover for up to 150 boats, a boat lift rated to 20 tonnes (suitable for vessels with standing masts), maintenance and repair work covering paintwork, fibreglass, engines, and rigging, plus a small boatshop.

Facilities on site include electricity, water, showers, toilets, Wi-Fi, and fuel.
