Designed by Gunnar Cardell and built by the Hungarian Shipyards & Crane Factory starting in 1977, this compact 21-footer represents solid Eastern European construction during an era when fiberglass sailboats were becoming more accessible worldwide. The Balaton 21 takes its name from Hungary's largest lake, where many of these boats first sailed. With a length overall of 21.33 feet and a waterline length of 18.70 feet, this masthead sloop offers respectable performance for its size. The fin keel configuration with transom-hung rudder provides good maneuverability, while the substantial displacement of 3,439 pounds and ballast-to-displacement ratio suggest a stable, seaworthy design suited for coastal cruising and day sailing. The boat's comfort ratio of 16.97 indicates a relatively stiff, performance-oriented design that won't be overly rolly at anchor, while the capsize screening formula of 2.13 places it within acceptable limits for protected waters sailing. The sail area of 225 square feet provides adequate power for the boat's displacement, making it suitable for both novice sailors seeking stability and experienced sailors wanting a manageable weekend cruiser. This design emphasizes seaworthiness over speed, making it an appealing choice for sailors prioritizing safety and comfort in near-shore environments.
