About the LM 27
The LM 27 was this builders most successful model and they were exported around the world including the US.
Designed by Palle Mortensen and built by LM Glasfiber A/S (DEN) from 1972–1986, the LM 27 is a robust Danish cruiser with 1535 hulls produced. Its full keel and moderate displacement of 8818.0 lb reflect a design philosophy prioritizing stability and durability over high-performance racing metrics.
- Best for:
- This boat suits coastal cruisers and weekend sailors who value a stable, easy-to-handle package with a shallow max draft of 3.12 ft, making it ideal for protected waters and marinas with limited depth.
- Bluewater capability:
- With a low capsize ratio of 1.75 and a high D/L ratio of 311.61, the LM 27 possesses the inherent stability and motion comfort suitable for protected offshore passages, though its age requires careful inspection of structural integrity.
- Comparables:
- It compares favorably to other 1970s European full-keel cruisers like the Beneteau First 27 or the Nauticat 27, sharing similar beam dimensions (9.02 ft) and a focus on comfortable, safe passage-making rather than speed.
