The hull is made of hand laid fibreglass. Generally, a hull made of hand laid fibreglass requires only a minimum of maintenance during the sailing season.


The boat is equipped with 5-7 berths, a galley and 240.0 liter fresh water capacity.

Rig of Hanse 342 anno 2006. Hanse 342, Long keel version

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.


The Hanse 342 has been built with more than one type of keel.

One option is 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.

Another option is a centerboard keel. A centerboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The keel is made of iron. Many people prefer lead keel in favour of iron. The main argument is that lead is much heavier than iron and a lead keel can therefore be made smaller which again result in less wet surface, i.e. less drag. In fact iron is quite heavy, just 30% less heavy than lead, so the advantage of a lead keel is often overstated. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.

The boat can only enter major marinas as the draft is about 1.85 - 1.95 meter (6.07 - 6.37 ft) dependent on the load. See immersion rate below.


Hanse 342 is typically equipped with an inboard Yanmar 3YM20 diesel engine at 21.0 hp (15 kW), which gives a max speed about 5.6 knots.

The transmission is a saildrive.

The fuel tank has a capacity of 80.0 liters (21 US gallons, 17 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 Hanse 342 is 1.99, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

EU classification

Hanse 342 holds one CE certification:

The boat is by European Union certified as Class A. OCEAN:
Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal conditions, and vessels largely self-sufficient.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 7.4 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 Hanse 342 is about 209 kg/cm, alternatively 1173 lbs/inch.
Meaning: if you load 209 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1173 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 Hanse 342 is 22.2.

Low High 31% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 31% of all similar sailboat designs. This comfort value is just below average.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Hanse 342 is 3.04.

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 Hanse 342 is 182 which categorizes this boat among 'light racers'.

Heavy Light 79% 0 50 100
79% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.

SA/D (Sail Area Displacement ratio)

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

The SA/D for Hanse 342 with ISO 8666 reference sail is 19.4, with a 135% genua the SA/D is 22.6.

Low High 85% 0 50 100
The SA/D ratio indicates that it is faster than 85% of all similar sailboat designs in light wind.

Over- / underrigged

Low High 93% 0 50 100
The Hanse 342 has more rig than 93% of all similar sailboats, which indicates that the boat is significantly overrigged.


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 36m2 (387 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.
