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 boat is equipped with 151.0 liter fresh water capacity.


Rig

The Konsort 29 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

The Konsort 29 has been built with different keel alternatives.

Fin keel

One option is 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 most marinas as the draft is just about 1.62 - 1.72 meter (5.31 - 5.61 ft) dependent on the load. See immersion rate below.

Fin keel

Another option is 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.

Konsort 29 can enter even shallow marinas as the draft is just about 1.01 - 1.11 meter (3.31 - 3.61 ft) dependent on the load. See immersion rate below.


Engine

The Konsort 29 has been equipped with different engine alternatives.

Alternative 1:

The boat may be equipped with an inboard Volvo Penta engine

Alternative 2:

The boat may be equipped with an inboard Bukh DV20ME diesel engine at 20 hp (14 kW). Calculated max speed is about 5.8 knots

The fuel tank has a capacity of 68.0 liters (17 US gallons, 14 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 Konsort 29 is 2.11, 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 6.8 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 Konsort 29 is about 170 kg/cm, alternatively 956 lbs/inch.
Meaning: if you load 170 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 956 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.

What is Motion Comfort Ratio (MCR)?

The Motion Comfort Ratio for Konsort 29 is 20.8.

Low High 42% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 42% 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 Konsort 29 is 2.68.

Slim Wide 88% 0 50 100
Compared with other similar sailboats it is more spacy than 88% of all other designs. It seems that the designer has chosen a significantly more spacy hull design.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Konsort 29 is 38%.

Low High 34% 0 50 100
This ballast ratio shows a righting moment that is higher than 34% of all similar sailboat designs. A righting moment (ability to resist heeling) just below average.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Konsort 29 is 229 which categorizes this boat among 'light crusers & offshore racers'.

Heavy Light 62% 0 50 100
62% of all similar sailboat designs are categorized as heavier. A light displacement requires less sailarea and has higher accellerations.


SA/D (Sail Area Displacement ratio)

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

Over- / underrigged

Low High 50% 0 50 100
The Konsort 29 has more rig than 50% of all similar sailboats, which indicates that this rig is spot on average!


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.
