Designed by Steven Schock and built by W. D. Schock Corp from 1997 onward, this compact 20-footer demonstrates impressive engineering in a trailerable package. The Harbor 20's fractional sloop rig and generous 220 square feet of sail area deliver spirited performance, while the fin keel with bulb and spade rudder configuration provides excellent maneuverability and upwind ability. With a displacement of 1,800 pounds and 50% ballast ratio, this fiberglass sailboat strikes an appealing balance between stability and responsiveness. The moderate beam of seven feet keeps the boat trailerable while still providing adequate interior space and stability for day sailing and weekend cruising. Her comfort ratio of 11.63 suggests quick motion in choppy conditions, making her better suited for day sailing and coastal cruising rather than extended offshore passages. The Harbor 20 excels as a spirited day sailer and capable small cruiser for protected waters. Her modern underbody design and efficient sail plan make her particularly appealing to sailors seeking good performance in a manageable size. The boat's modest draft of 3.5 feet opens up shallow anchorages while maintaining enough depth for solid upwind performance, making her ideal for exploring coastal waters and smaller lakes.
