Recognized as a moderate-weight vessel, the LM 23 established a reputation as a stable and capable coastal cruiser, appealing to those seeking a dependable and comfortable platform for family adventures.

The creation of the LM 23 falls within a pivotal period for LM Glasfiber, a company that began as a furniture factory before pioneering fiberglass boat construction in the 1950s. From 1969 to 1975, the LM 23 was a testament to LM Glasfiber's manufacturing ethos, which emphasized durability, ease of maintenance, and robust construction. The designer, Palle Mortensen, aimed for a functional and relatively spacious hull design for its size, catering to the growing market of family-friendly cruisers. This design philosophy aligned perfectly with LM Glasfiber's commitment to producing practical vessels with comfortable accommodations, a hallmark of their yachts during this era. The boat's construction utilized solid fiberglass for both the hull and deck, ensuring a strong and long-lasting vessel.

Sailing Performance and Handling

With a length overall of 23.29 feet and a long keel, the LM 23 is characterized by its stable and predictable handling. While described as a moderate-weight sailboat that is slightly underpowered, it boasts significant stability and good righting capability, making it a reassuring vessel in various conditions. Its average hull design, combined with a relatively high ballast-to-displacement ratio, contributes to its stiff and steady motion through the water. Many LM 23s were equipped with reliable inboard diesel engines, such as those from Volvo Penta or Bukh, providing a comfortable top speed of approximately 6.0 knots under power. This auxiliary power capability, along with its stable sailing characteristics, reinforces its identity as a versatile motor sailer, well-suited for coastal exploration where a blend of sailing and motoring efficiency is valued.

Accommodations and Layout

Despite its compact size, the LM 23 is noted for its surprisingly spacious interior, which some reviews suggest is roomier than many comparable designs of its era. The designer prioritized interior volume, contributing to a comfortable living space for a vessel of just over 23 feet. The interior typically features traditional mahogany woodwork, lending a classic and warm aesthetic to the cabin. While detailed layouts can vary, a common arrangement for the LM 23 includes one cabin with two main berths, often supplemented by convertible dinette spaces or additional quarter berths, maximizing the utility of the available space. The solid fiberglass deck provides a strong foundation for the topsides, and while specific headroom figures are not widely publicized, the overall design aimed for functional comfort within its dimensions.
