Hull

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.

Interior

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.

The boat is equipped with 3 cabins, 5-6 berths, a galley, 110.0 liter fresh water capacity and toilet facility.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

Rig

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.

Keel

**Fin keel**

The Albin Alpha 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.

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.

Albin Alpha can enter most marinas as the draft is just about 1.65 - 1.75 meter (5.41 - 5.71 ft) dependent on the load. See immersion rate below.

Engine

The boat is typically equipped with an inboard Yanmar diesel engine at 9 hp (6 kW). The speed is 6.0 knots.

The fuel tank, which is made of stainless steel, has a capacity of 45.0 liters (11 US gallons, 9 imperial gallons).

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 Albin Alpha is 1.92, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.5 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.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Albin Alpha is about 136 kg/cm, alternatively 764 lbs/inch.

Meaning: if you load 136 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 764 lbs cargo on the boat it will sink 1 inch.

Bottom Paint

When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 24m^{2} (258 ft^{2}).

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.
