The deck is a double deck which improves the indoor climate.
The boat is equipped with 2 cabins, 7-9 berths, a galley and toilet facility.
The headroom is above average
The Hallberg-Rassy 42E is equipped with a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.
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.
The boat can only enter major marinas as the draft is about 2.05 - 2.15 meter (6.73 - 7.03 ft) dependent on the load. See immersion rate below.
Hallberg-Rassy 42E is typically equipped with an inboard Volvo Penta TMD31 diesel engine at 95.0 hp (70 kW).
The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive e.g. a sail drive.
The fuel tank which is made of stainless steel has a capacity of 395.0 liters (104 US gallons, 86 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.
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 Hallberg-Rassy 42E is about 265 kg/cm, alternatively 1489 lbs/inch.
Meaning: if you load 265 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1489 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 31m2 (333 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.
If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
