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.
The boat is equipped with 5 berths, a galley and toilet facility.
The headroom is near average
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.
The Albin 78 Cirrus is equipped with a finn keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long 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.
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 finn 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 even shallow marinas as the draft is just about 1.49 - 1.59 meter (4.89 - 5.19 ft) dependent on the load. See immersion rate
Albin 78 Cirrus is typically equipped with an inboard Volvo Penta MD5 diesel engine at 7.0 hp (5 kW), which gives a max speed about 4.0 knots.
The transmission is a saildrive.
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
Theoretical Maximum Hull Speed
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 6.3 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 Albin 78 Cirrus is about 123 kg/cm, alternatively 691 lbs/inch.
Meaning: if you load 123 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 691 lbs cargo on the boat it will sink 1 inch.
This section is statistical comparison with similar boats of the same category.

What is Motion Comfort Ratio (MCR)?
The Motion Comfort Ratio for Albin 78 Cirrus is 18.3.
Comparing this ratio with similar sailboats show that it is more comfortable than 46% of all similar sailboat designs.
This comfort value is just below average.
L/B (Length Beam Ratio)
What is L/B (Length Beam Ratio)?
The l/b ratio for Albin 78 Cirrus is 2.84.
Compared with other similar sailboats it is more spacy than 73% of all other designs.
It seems that the designer has chosen a slightly more spacy hull design.
What is a Ballast Ratio?
The ballast ratio for Albin 78 Cirrus is 40%.
This ballast ratio shows a righting moment that is higher than 50% of all similar sailboat designs.
This righting moment (ability to resist heeling) is spot on average!
D/L (Displacement Length Ratio)
What is Displacement Length Ratio?
The DL-ratio for Albin 78 Cirrus is 222 which categorizes this boat among 'light crusers & offshore racers'.
54% of all similar sailboat designs are categorized as heavier.
A light displacement requires less sailarea and has higher accellerations.
SA/D (Sail Area Displacement ratio)
What is SA/D (Sail Area Displacement ratio)?
The SA/D for Albin 78 Cirrus with ISO 8666 reference sail is 14.7, with a 135% genua the SA/D is 17.3.
The SA/D ratio indicates that it is faster than 31% of all similar sailboat designs in light wind.
Over- / underrigged
The Albin 78 Cirrus has more rig than 46% of all similar sailboats, which indicates that the boat is slightly underrigged.
RSP (Relative Speed Performance)
What is Relative Speed Performance?
The Relative Speed Performance for Albin 78 Cirrus is 54
The relative speed performance is 54 which means that a it is faster than 54% of all similar sailboat designs.
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 21m2 (226 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.
