Review of LM 32


LM 32
LM 32 anno 1984.


Basic specs.

sail specifications
The LM 32 is a motorsailer designed by the Danish maritime architect Bent Juul Andersen in the late seventies. A few hundred boats have been produced. The LM 32 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.
The deck is a double deck which improves the indoor climate.

The interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 6 berths, a galley, toilet facility and 75.0 liter waste water capacity.
The headroom is above average
Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

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
Keel
Keel of LM 32 anno 1980.

The LM 32 has been built with more than one type of keel.

One option is 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 keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

LM 32 can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.


Engine

The boat is typically equipped with an inboard Volvo Penta MD2030 diesel engine at 28.0 hp (20 kW), which gives a max speed about 5.6 knots.

The fuel tank has a capacity of 250.0 liters (66 US gallons, 54 imperial gallons).


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 32 is 1.77, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.1 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for LM 32 is about 184 kg/cm, alternatively 1033 lbs/inch.
Meaning: if you load 184 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1033 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.

Motion Comfort Ratio

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for LM 32 is 31.4.

Low High 86% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 86% of all similar sailboat designs. This is a comfort value significantly above average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for LM 32 is 3.01.

Slim Wide 66% 0 50 100
Compared with other similar sailboats it is more spacy than 66% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for LM 32 is 285 which categorizes this boat among 'medium weight cruisers'.

Heavy Light 34% 0 50 100
34% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.


SA/D (Sail Area Displacement ratio)

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

The SA/D for LM 32 with ISO 8666 reference sail is 11.7, with a 135% genua the SA/D is 14.0.

Low High 4% 0 50 100
The SA/D ratio indicates that it is faster than 4% 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 31% 0 50 100
The LM 32 has more rig than 31% 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 32 is 18

Slow Fast 18% 0 50 100
The relative speed performance is 18 which means that a it is faster than 18% 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.


Maintenance

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 30m2 (322 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.

Note: If you use a paint roller you will need more paint than if you use a paintbrush.
