The LM 28 represents a significant evolutionary step for the Danish builder LM Glasfiber, marking the transition from the traditional, longkeeled motor sailer aesthetic of the iconic LM 27 toward a more modern, performanceoriented cruising yacht. Introduced in the early 1980s and designed by Bent Juul Andersen, the LM 28 was intended to bridge the gap for sailors who demanded the protection of a wheelhouse without sacrificing the pointing ability and responsiveness of a contemporary finkeel sloop. While it retains the signature rounded stern and robust scantlings synonymous with the yard, the 28 features a more efficient underwater profile that distinguishes it from its more sedentary predecessors.

Sailing Performance & Handling

Unlike the LM 27, which relied on a long, shallow keel for stability, the LM 28 utilizes a fin keel and a balanced spade rudder. This configuration significantly improves the yacht's "bite" into the water, allowing it to tack more reliably and maintain better speed through the air. With a displacement of approximately 4,000 kg and a ballast ratio often exceeding 35%, the boat is notably stiff, making it an exceptionally safe platform for North Sea and coastal cruising.

In editorial evaluations, such as those featured in Practical Boat Owner, the LM 28 is frequently praised for its dual-steering capability. In fair weather, the sailor can use the transom-mounted tiller to gain a tactile feel for the hull's balance; in inclement weather, the internal wheelhouse steering allows for comfortable passage-making while protected from the elements. While the sail area-to-displacement ratio is modest compared to a dedicated racing yacht, the LM 28 carries its canvas well into the upper wind ranges. Owners often report that the boat feels most at home in Force 4 to 6 conditions, where its weight provides a predictable, sea-kindly motion that minimizes slamming in a head sea.

Interior Comfort & Variations

The interior of the LM 28 is a masterclass in Scandinavian spatial efficiency, defined by high-quality joinery and a unique "split-level" living concept. The most defining feature is the placement of the galley, which is located up in the wheelhouse area rather than down in the main saloon. This arrangement allows the cook to remain socially connected with the crew and provides excellent ventilation and views through the large wheelhouse windows.

The main cabin features a traditional layout with a central drop-leaf table flanked by two longitudinal settees that double as berths. Moving forward, a compact heads compartment is situated between the saloon and the V-berth in the bow. One of the notable sibling variations is the LM 30, which followed a similar design language but offered significantly more volume and a separate aft cabin in some configurations. The LM 28’s sister, the LM 27, is often compared as the more "traditional" alternative, featuring a smaller interior volume and a slower, long-keel hull. In the 28, the use of light-colored fabrics and extensive teak or mahogany woodwork creates a warm, "ship-shape" atmosphere that has aged remarkably well.

The LM 28 maintains a dedicated following across Northern Europe and the United Kingdom, often highlighted in regional maritime media for its longevity. It is frequently cited in "Used Boat" buyer guides by Yachting Monthly as a premier choice for couples seeking a rugged, all-weather cruiser. Its cultural footprint is most visible in the Baltic and North Sea cruising communities, where it is regarded as a "Land Rover of the Seas"—unpretentious, durable, and capable of handling deteriorating conditions with poise.

Known Issues & Buyer’s Checklist

Prospective buyers should focus their inspections on the specific mechanical and structural nuances of the LM build style.

  1. Saildrive Diaphragm: Most LM 28s were fitted with Bukh or Volvo Penta engines utilizing a saildrive. The rubber seal (diaphragm) has a recommended replacement interval of 7 years; if the service history is unclear, this should be a priority.
  2. Wheelhouse Window Leaks: The large toughened glass windows are a hallmark of the model, but the original rubber seals can perish over decades. Check for water staining on the woodwork below the galley and steering station.
  3. Rudder Play: Because the boat utilizes a spade rudder, the bearings are subject to wear. Excessive "thumping" or vibration while under motor may indicate that the rudder stock bushings require replacement.
  4. Gelcoat Crazing: While LM Glasfiber was known for superior hull construction, the deck molds occasionally show stress crazing around the stanchion bases or the transition points of the wheelhouse structure.
  5. Bukh Engine Components: Many units still carry the original Danish-built Bukh engines. While legendary for their reliability, parts can be expensive. Check the exhaust elbow for carbon buildup or corrosion.

Community & Resources

The primary hub for technical support and historical data is the LM Owners Association, a UK-based organization that provides an extensive archive of manuals, wiring diagrams, and member-led advice on restoration. In Denmark, the "LM Klubben" serves as a similar repository for original factory specifications and organizes annual rallies for the various LM models.

The Verdict

The LM 28 remains a top-tier choice for sailors who prioritize comfort, protection, and build quality over raw racing speed. It successfully modernized the motor sailer concept without losing the "bulletproof" feel that made LM Glasfiber a household name in Denmark.

Pros:

  • Excellent protection from the elements via the integrated wheelhouse.
  • Superior build quality and joinery compared to many contemporary mass-produced yachts.
  • The dual-steering system offers versatility for both "purist" sailing and motor-sailing.
  • High stability and predictable handling in heavy weather.

Cons:

  • Higher price point on the used market compared to standard 28-foot cruisers.
  • The galley-up configuration reduces the size of the cockpit for social lounging.
  • Modest light-wind performance due to high displacement and wetted surface area.
