Review of LM 26


LM 26
LM 26.


Basic specs.

sail specifications
The LM 26 is a motorsailer designed by the Danish maritime architect Bent Juul Andersen in the early eighties. A few hundred boats have been produced. The LM 26 is built by the Danish yard LM Glasfiber A/S.

Hull
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.

Interior
The boat is equipped with 2 cabins and 6 berths.

Rig
The boat 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.

Keel

The LM 26 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with 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.


Engine

LM 26 is typically equipped with an inboard Bukh DV20 diesel engine at 20.0 hp (14 kW).

The transmission is a saildrive.


Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

Stability and Safety

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.


Immersion rate

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.


Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for LM 26 is 2.79.

Slim Wide 79% 0 50 100
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.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for LM 26 is 43%.

Low High 66% 0 50 100
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.


SA/D (Sail Area Displacement ratio)

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.

Low High 8% 0 50 100
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.


Over- / underrigged

Low High 34% 0 50 100
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.


RSP (Relative Speed Performance)

What is Relative Speed Performance?

The Relative Speed Performance for LM 26 is 12

Slow Fast 12% 0 50 100
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.
