Jachthaven Dragt is a marina in Aalsmeer, Noord-Holland, situated on the edge of the Westeinderplassen — a sprawling water area of more than 20 km² made up of one large lake and several smaller ones, all connected by a network of narrow channels.

From the marina, boaters can explore the many small islands of the Westeinderplassen and navigate onward to destinations such as Amsterdam and Leiden. Berth holders moor directly at the marina's own jetties.

For those without a boat, the marina offers the option to rent a Van Wijk 621 sloep at a reduced rate for berth holders; specific pricing is available through the harbourmaster.
