Hull

Both the hull and the deck 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.

Both the hull and the deck is a sandwich construction which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin.


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, 6 berths, a galley, 135.0 liter fresh water capacity and toilet facility.

Rig

The Nordship 28 is built with 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.


Keel

Fin keel

The Nordship 28 is built with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than 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. 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 1.60 - 1.70 meter (5.25 - 5.55 ft) dependent on the load. See immersion rate below.


Engine

The Nordship 28 has been equipped with different engine alternatives.

Alternative 1:

Nordship 28 may be equipped with an inboard Volvo Penta MD11C engine at 23 hp (17 kW). The speed is 6.5 knots.

The transmission is a saildrive.

Alternative 2:

The boat may be equipped with an inboard Volvo Penta MD11 engine at 13 hp (9 kW). Calculated max speed is about 4.5 knots

The transmission is a saildrive.

Alternative 3:

The boat may be equipped with an inboard Volvo Penta 2003 engine at 28 hp (20 kW). Calculated max speed is about 6.6 knots

The transmission is a saildrive.

Alternative 4:

Nordship 28 may be equipped with an inboard Volvo Penta 2002 engine at 18 hp (13 kW). Calculated max speed is about 5.3 knots

The transmission is a saildrive.

The fuel tank, which is made of stainless steel, has a capacity of 135.0 liters (35 US gallons, 29 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.

Stability and Safety

What is Capsize Screening Formula (CSF)?

The capsize screening value for Nordship 28 is 1.94, 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 Nordship 28 is about 141 kg/cm, alternatively 791 lbs/inch.
Meaning: if you load 141 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 791 lbs cargo on the boat it will sink 1 inch.


Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

Motion Comfort Ratio

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Nordship 28 is 24.3.

Low High 66% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 66% of all similar sailboat designs. This comfort value is just above average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Nordship 28 is 2.92.

Slim Wide 66% 0 50 100
Compared with other similar sailboats it is more spacy than 66% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Nordship 28 is 41%.

Low High 54% 0 50 100
This ballast ratio shows a righting moment that is higher than 54% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Nordship 28 is 288 which categorizes this boat among 'medium weight cruisers'.

Heavy Light 34% 0 50 100
34% of all similar sailboat designs are categorized as heavier. A heavy displacement combined with smaller water plane area has lower acceleration and is more comfortable.


SA/D (Sail Area Displacement ratio)

What is SA/D (Sail Area Displacement ratio)?

The SA/D for Nordship 28 with ISO 8666 reference sail is 15.2, with a 135% genua the SA/D is 18.0.

Low High 42% 0 50 100
The SA/D ratio indicates that it is faster than 42% of all similar sailboat designs in light wind.


Over- / underrigged

Low High 42% 0 50 100
The Nordship 28 has more rig than 42% 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 Nordship 28 is 50

Slow Fast 50% 0 50 100
The relative speed performance is 50 which means that a it is faster than 50% of all similar sailboat designs.


Maintenance

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 24m2 (258 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.
