About the Lm 16 Sailboat

Danish designer Palle Mortensen created this compact coastal cruiser during the late 1960s, and Lm Glasfiber A/S produced 455 examples between 1967 and 1972. The fiberglass construction features a traditional long keel configuration that provides excellent directional stability and seakindly motion in choppy conditions, making it well-suited for coastal exploration and weekend cruising. At just over 16 feet with a generous beam of 6.56 feet, this fractional sloop offers surprising interior volume for its size while maintaining manageable proportions for single-handed sailing or small crew adventures. The long keel design, while not optimized for racing performance, delivers predictable handling characteristics that build confidence in novice sailors and provides a forgiving platform for learning coastal navigation skills. With 121 square feet of sail area driving 1,874 pounds of displacement, the boat delivers moderate performance with emphasis on stability over speed. The 2.13 capsize screening formula indicates good stability for protected waters and coastal conditions, though the design isn't intended for serious offshore passages. The modest draft of just over two feet opens up shallow anchorages and creek exploration that deeper-keeled boats cannot access, making it an appealing choice for gunkholing and day sailing adventures.
