Designed by renowned naval architect Jim Antrim and built by Ultimate Sailboats International starting in 1996, this 28-foot performance cruiser strikes an impressive balance between speed and versatility. The boat's most distinctive feature is its innovative lifting keel configuration, which retracts to reduce the standard 6-foot draft for shallow-water exploration while maintaining excellent upwind performance when fully deployed. With its fractional sloop rig and fiberglass construction, the Antrim 27 delivers spirited sailing characteristics that appeal to both weekend cruisers and club racers. The generous sail area of 489 square feet combined with a relatively light 2,600-pound displacement creates a responsive boat that accelerates quickly in light air and maintains good speed across various wind conditions. The design's low comfort ratio of 8.31 reflects its performance-oriented nature rather than traditional cruising accommodations, while the capsize screening value of 2.69 indicates good stability for coastal sailing adventures. The lifting keel system makes this boat particularly attractive for sailors who want to explore gunkholes and shallow anchorages without sacrificing sailing performance, making it well-suited for coastal cruising, day sailing, and light recreational racing in protected waters.
