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.

The boat is equipped with 5 berths, a galley, 90.0 liter fresh water capacity and toilet facility.


Rig

Rig of Kudu.

The Kudu 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

Fin keel

The Kudu is equipped 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 boat can enter even shallow marinas as the draft is just about 1.45 - 1.55 meter (4.76 - 5.06 ft) dependent on the load. See immersion rate below.


Engine

The Kudu has been equipped with different engine alternatives.

Alternative 1:

Kudu may be equipped with an inboard Volvo Penta diesel engine at 8 hp (5 kW). Calculated max speed is about 4.7 knots

Alternative 2:

The boat may be equipped with an inboard Farymann L30 diesel engine at 9 hp (6 kW). Calculated max speed is about 5.0 knots

The fuel tank has a capacity of 25.0 liters (6 US gallons, 5 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 Kudu is 2.32, indicating that this boat would not 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 5.9 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.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Kudu is about 112 kg/cm, alternatively 630 lbs/inch.
Meaning: if you load 112 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 630 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 Kudu is 15.1.

Low High 38% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 38% 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 Kudu is 2.64.

Slim Wide 85% 0 50 100
Compared with other similar sailboats it is more spacy than 85% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Kudu is 232 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 42% 0 50 100
42% 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 19m2 (204 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
