About the Parker 21 Trailer Sailer 21 Sailboat

Designed by renowned naval architect Ron Holland and built by Parker Yachts in the UK from 1982 to 1998, this compact trailer sailer represents an ideal entry point into sailing for those seeking versatility and convenience. With just 100 units produced during its 16-year production run, the Parker 21 has earned a reputation as a well-crafted boat that punches above its weight class. The lifting keel design is the boat's standout feature, allowing access to shallow waters and easy launching from boat ramps while maintaining respectable sailing performance with its 3.75-foot draft when lowered. The fractional sloop rig delivers a balanced sail plan that's manageable for small crews, while the fiberglass construction ensures durability and low maintenance. At 1,950 pounds with 800 pounds of ballast, this boat strikes an excellent balance between trailerable weight and stability. The generous beam of 8.16 feet provides surprising interior volume for weekend cruising, while the moderate displacement and 220 square feet of sail area offer spirited performance in coastal waters. With a comfort ratio of 9.47, the Parker 21 favors quick, responsive sailing over heavy-weather passages, making it perfect for day sailing, coastal exploring, and short cruising adventures where the ability to trailer home adds tremendous flexibility to your sailing plans.
