Review of LM 26

Both the hull and the deck is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat is equipped with 2 cabins and 6 berths.

The LM 26 is equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

Fin keel

The LM 26 is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.

The boat can enter even shallow marinas as the draft is just about 1.25 - 1.35 meter (4.10 - 4.40 ft) dependent on the load. See immersion rate below.

LM 26 may be equipped with an inboard Bukh DV20 diesel engine at 20 hp (14 kW).

The transmission is a saildrive.

What is Capsize Screening Formula (CSF)?

The capsize screening value for LM 26 is 2.03, indicating that this boat would not be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for LM 26 is about 157 kg/cm, alternatively 881 lbs/inch.
Meaning: if you load 157 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 881 lbs cargo on the boat it will sink 1 inch.

What is L/B (Length Beam Ratio)?

The l/b ratio for LM 26 is 2.79.

Compared with other similar sailboats it is more spacy than 79% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.

What is a Ballast Ratio?

The ballast ratio for LM 26 is 43%.

This ballast ratio shows a righting moment that is higher than 66% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.

What is SA/D (Sail Area Displacement ratio)?

The SA/D for LM 26 with ISO 8666 reference sail is 11.9, with a 135% genua the SA/D is 13.8.

The SA/D ratio indicates that it is faster than 8% of all similar sailboat designs in light wind.
Don't panic! It is expected that motor sailers has a low SA/D value as this is the natural consequence of the design combining sailing and motor boat characteristics.

The LM 26 has more rig than 34% of all similar sailboats, which indicates that the boat is slightly underrigged.
It is expected that motor sailers are underrigged as this is the natural consequence of combining sailing and motor characteristics.

What is Relative Speed Performance?

The Relative Speed Performance for LM 26 is 12

The relative speed performance is 12 which means that a it is faster than 12% of all similar sailboat designs. As this boat is a motor sailer, it is expected that the performance of a motor sailer for sail alone is lower than a dedicated sailboat.
