The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The hull is a double hull which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.
The interior is like many other boats made of mahogany.
The boat is equipped with 4 cabins, 6 berths, a galley, toilet facility and 70 liter waste water capacity.
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.
The boat is typically equipped with an inboard Yanmar diesel engine at 97.0 hp (72 kW), which gives a max speed about 7.9 knots.
The fuel tank has a capacity of 285 liters (75 US gallons, 62 imperial gallons).
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 Malö 42 is 1.69, 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 7.9 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Malö 42 is about 283 kg/cm, alternatively 1586 lbs/inch.
Meaning: if you load 283 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1586 lbs cargo on the boat it will sink 1 inch.

Motion Comfort Ratio
What is Motion Comfort Ratio (MCR)?
The Motion Comfort Ratio for Malö 42 is 39.8.
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 Malö 42 is 3.30.
Compared with other similar sailboats it is more spacy than 58% 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 Malö 42 is 315 which categorizes this boat among 'medium weight cruisers'.
15% 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.
