Danish designer Palle Mortensen created a thoroughly seaworthy coastal cruiser when he penned the Lm 27 for Lm Glasfiber in the early 1970s. This masthead sloop exemplifies the solid European approach to small boat design, featuring a traditional long keel configuration that provides excellent tracking and seakeeping abilities at the expense of some maneuverability in tight quarters. Built from 1972 to 1986 with 1,535 hulls launched, the Lm 27 earned a reputation as a capable offshore boat despite its modest 27-foot length. The substantial displacement of 8,818 pounds and generous ballast ratio create a stiff, stable platform that inspires confidence in heavy weather. Her comfort ratio of 29.68 indicates excellent motion characteristics for extended passages, while the conservative capsize screening formula of 1.75 reflects good stability margins for serious coastal and offshore work. The 323-square-foot sail plan provides adequate power for her displacement, though performance-oriented sailors may find her more suited to comfortable passage-making than spirited sailing. With her long keel and substantial construction, this Danish design appeals to cruising sailors who prioritize seaworthiness and comfort over speed, making her an excellent choice for couples seeking a proven small cruiser for coastal exploration and weekend getaways.
