Hull

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

Interior

The boat is equipped with 2 cabins, 4 berths, a galley and toilet facility.

Rig

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.

Keel

The Oceanis 411 Celebration is equipped with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.The Oceanis 411 Celebration is equipped with a L keel. The keel is an L-shape and therefore less exposed to seaweed, fishing nets and lines.

The boat can only enter major marinas as the draft is about 2.00 - 2.10 meter (6.56 - 6.86 ft) dependent on the load. See immersion rate below.

Engine

Oceanis 411 Celebration is typically equipped with an inboard Volvo Penta D2 diesel engine at 55.0 hp (40 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.

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 Oceanis 411 Celebration is 2.00, indicating that this boat would not be accepted to participate in ocean races.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Oceanis 411 Celebration is about 337 kg/cm, alternatively 1889 lbs/inch.
Meaning: if you load 337 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1889 lbs cargo on the boat it will sink 1 inch.
