Rig

The Markant 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

Unknown keel type

The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.

The boat can enter even shallow marinas as the draft is just about 1.27 - 1.37 meter (4.17 - 4.47 ft) dependent on the load. See immersion rate below.


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 Markant is 1.80, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Markant is about 158 kg/cm, alternatively 888 lbs/inch.
Meaning: if you load 158 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 888 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.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Markant is 3.56.

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

What is a Ballast Ratio?

The ballast ratio for Markant is 42%.

Low High 58% 0 50 100
This ballast ratio shows a righting moment that is higher than 58% of all similar sailboat designs. A righting moment (ability to resist heeling) just above average.


SA/D (Sail Area Displacement ratio)

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

The SA/D for Markant with ISO 8666 reference sail is 14.8, with a 135% genua the SA/D is 17.6.

Low High 34% 0 50 100
The SA/D ratio indicates that it is faster than 34% of all similar sailboat designs in light wind.


Over- / underrigged

Low High 85% 0 50 100
The Markant has more rig than 85% of all similar sailboats, which indicates that the boat is significantly overrigged.


RSP (Relative Speed Performance)

What is Relative Speed Performance?

The Relative Speed Performance for Markant is 3

Slow Fast 3% 0 50 100
The relative speed performance is 3 which means that a it is faster than 3% of all similar sailboat designs.
