The boat is equipped with 0 cabins, 6-9 berths, 370.0 liter fresh water capacity and toilet facility.
The Oceanis 46.1 is 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 gennaker or a spinnaker for optimal speed.
The Oceanis 46.1 has been built with different keel alternatives.
L-shape fin keel
One option is a L keel. An L-shape keel is a bulb keel with the shape as an L. This keel is less exposed to seaweed, fishing nets and lines.
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 2.35 - 2.45 meter (7.71 - 8.01 ft) dependent on the load. See immersion rate below.
L-shape fin keel
Another option is a L keel. An L-shape keel is a bulb keel with the shape as an L. This keel is less exposed to seaweed, fishing nets and lines.
This keel is also made of iron.
Oceanis 46.1 can enter most marinas as the draft is just about 1.75 - 1.85 meter (5.74 - 6.04 ft) dependent on the load. See immersion rate below.
L-shape fin keel
Another option is a L keel. An L-shape keel is a bulb keel with the shape as an L. This keel is less exposed to seaweed, fishing nets and lines.
The boat can only enter major marinas as the draft is about 2.65 - 2.75 meter (8.69 - 8.99 ft) dependent on the load. See immersion rate below.
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 Capsize Screening Formula (CSF)?
The capsize screening value for Oceanis 46.1 is 2.07, indicating that this boat would not be accepted to participate in ocean races.
Oceanis 46.1 holds three CE certifications:
If less than 10 in on board the boat is by European Union certified as Class A. OCEAN:If less than 11 in on board the boat is by European Union certified as Class B. OFFSHORE:
If less than 12 in on board the boat is by European Union certified as Class C. INSHORE:
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 8.8 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 Oceanis 46.1 is about 399 kg/cm, alternatively 2235 lbs/inch.
Meaning: if you load 399 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2235 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 68m2 (731 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.
