The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 8/10 berths and 550.0 liter fresh water capacity.
The Oceanis 461 has been built with different keel alternatives.
Unknown keel type
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. As the surface of a fin type keel is just a fraction of the total wet surface, the difference between an iron keel and a lead keel can in reality be ignored for cruising yachts.
The boat 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.
Fin keel
The Oceanis 461 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.
Oceanis 461 can enter most marinas as the draft is just about 1.73 - 1.83 meter (5.68 - 5.98 ft) dependent on the load. See immersion rate below.
The Oceanis 461 has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an inboard Yanmar 4JH2-E diesel engine
Alternative 2:
The boat may be equipped with an engine at 56 hp (41 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Oceanis 461 is 2.03, indicating that this boat would not be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Oceanis 461 is about 399 kg/cm, alternatively 2237 lbs/inch.
Meaning: if you load 399 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2237 lbs cargo on the boat it will sink 1 inch.

Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 22.67
