Marina Kaap Hoorn is a yacht marina situated on the eastern side of the town of Hoorn, along the Hoornsche Hop — a popular sailing area on the Markermeer and IJsselmeer.

The marina serves as a nautical centre rather than a simple boat park, with around 145 berths of various sizes and a full range of modern amenities including electricity hookups at each berth, water, WiFi, atmospheric jetty lighting, and a waste-separation facility.

A full-service shipyard with a 34-ton boat lift is also on site. The location makes it a convenient access point for exploring the broader Markermeer and IJsselmeer waters, and boat and yacht rentals are available directly from the marina.

A boat ramp provides additional access for trailered craft. The western boundary of the marina area is expected to develop into a nature reserve in the future.
