The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The Oceanis 400 is 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.
Deep keel
The Oceanis 400 is equipped with a deep keel. A deep keel provide a better healing moment than a shallow keel.
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 enter most marinas as the draft is just about 1.70 - 1.80 meter (5.58 - 5.88 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard Yanmar 4JH2-E diesel engine at 44 hp (32 kW).
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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Oceanis 400 is about 312 kg/cm, alternatively 1748 lbs/inch.
Meaning: if you load 312 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1748 lbs cargo on the boat it will sink 1 inch.
