The deck is made of fibreglass.
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 0 cabins, 11 berths, a galley, 480.0 liter fresh water capacity and toilet facility.
The boat has more than one rig.
One option is 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.
The Sun Magic 44 has been built with different keel alternatives.
Fin keel
One option is 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.
Sun Magic 44 can only enter major marinas as the draft is about 2.13 - 2.23 meter (6.99 - 7.29 ft) dependent on the load. See immersion rate below.
CentreBoard
Another option is a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.
This keel is also made of iron.
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 below.
The boat is typically equipped with an inboard Yanmar Turbo JH-TE diesel engine at 55 hp (40 kW). The speed is 8.0 knots.
The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.
The fuel tank, which is made of stainless steel, has a capacity of 220.0 liters (58 US gallons, 48 imperial gallons).
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 Sun Magic 44 is 1.96, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 7.9 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 Sun Magic 44 is about 302 kg/cm, alternatively 1694 lbs/inch.
Meaning: if you load 302 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1694 lbs cargo on the boat it will sink 1 inch.

What is SA/D (Sail Area Displacement ratio)?
The SA/D for Sun Magic 44 with ISO 8666 reference sail is 15.4, with a 135% genua the SA/D is 18.3.
Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 51m2 (548 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.
