About the Offshore 28 Luders Sailboat

Designed by the renowned A.E. Luders and built by Hong Kong's respected Cheoy Lee Shipyard starting in 1972, this 28-foot masthead sloop represents classic American design sensibilities executed with Asian craftsmanship. The fiberglass construction features a moderate displacement hull with a distinctive keel/centerboard configuration, offering the best of both worlds for coastal cruising enthusiasts. With her traditional lines and well-balanced proportions, the Offshore 28 delivers respectable performance under sail while maintaining the comfort and stability desired for extended cruising. The boat's substantial ballast-to-displacement ratio and moderate beam create a stiff, seaworthy platform that inspires confidence in challenging conditions. Her centerboard design provides draft flexibility for exploring shallow waters while maintaining the tracking ability of a deeper keel when fully deployed. The Luders pedigree brings proven sailing characteristics to this compact cruiser. While compact at just under 28 feet overall, the thoughtful design maximizes interior volume and deck space. The masthead sloop rig provides simple, efficient sail handling, making this boat well-suited for couples or small families seeking coastal adventures. Her moderate displacement and comfortable motion make her equally at home day sailing or weekend cruising in protected waters.
