sail specifications
The Fjord MS 33 also known as Fjord 33 MS is a motorsailer designed by the Norwegian maritime architect Eivind Amble in the early seventies. Less than 100 boats have been produced. The Fjord MS 33 is built by the Norwegian yard Fjord Plast A/S.

Hull

Both the hull and the deck is made of hand laid fibreglass. Generally, a hull made of hand laid 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 boat is equipped with 2 cabins, 5-6 berths, a galley, 200.0 liter fresh water capacity and toilet facility.


Rig

The Fjord MS 33 is equipped 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

Full keel

The Fjord MS 33 is equipped with a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.

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.

The boat can enter even shallow marinas as the draft is just about 1.35 - 1.45 meter (4.43 - 4.73 ft) dependent on the load. See immersion rate below.


Engine

The Fjord MS 33 has been equipped with different engine alternatives.

Alternative 1:

Fjord MS 33 may be equipped with an inboard Volvo Penta 2003 T diesel engine at 43 hp (32 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.

Alternative 2:

The boat may be equipped with an inboard Volvo Penta engine at 36 hp (26 kW). Calculated max speed is about 6.0 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.

Alternative 3:

The boat may be equipped with an inboard Perkins engine at 47 hp (35 kW). Calculated max speed is about 6.9 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.

Note: Norwegian boats had Perkins 47hp as standard engine.

The fuel tank, which is made of stainless steel, has a capacity of 200.0 liters (52 US gallons, 43 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 Fjord MS 33 is 1.69, 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 7.1 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 Fjord MS 33 is about 182 kg/cm, alternatively 1023 lbs/inch.
Meaning: if you load 182 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1023 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 Fjord MS 33 is 35.0.

Low High 93% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 93% of all similar sailboat designs. This is a comfort value significantly above average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Fjord MS 33 is 3.12.

Slim Wide 58% 0 50 100
Compared with other similar sailboats it is more spacy than 58% 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 Fjord MS 33 is 49%.

Low High 85% 0 50 100
This ballast ratio shows a righting moment that is higher than 85% of all similar sailboat designs. A righting moment (ability to resist heeling) significantly above average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Fjord MS 33 is 317 which categorizes this boat among 'medium weight cruisers'.

Heavy Light 21% 0 50 100
21% 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.


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 29m2 (312 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.


Rig

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
