Hull
The hull 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.
Rig

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.
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 Marieholm 32E is 1.87, 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 6.5 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 Marieholm 32E is about 144 kg/cm, alternatively 810 lbs/inch.
Meaning: if you load 144 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 810 lbs cargo on the boat it will sink 1 inch.
