Hull

The hull 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.

Interior

The boat is equipped with 4 berths, a galley, 129.0 liter fresh water capacity and toilet facility.

Keel

Full keel

The Master mariner 22 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 boat can enter even shallow marinas as the draft is just about 0.92 - 1.02 meter (3.02 - 3.32 ft) dependent on the load. See immersion rate below.

Engine

The Master mariner 22 has been equipped with different engine alternatives.

Alternative 1:

Master mariner 22 may be equipped with an inboard Bukh 20 diesel engine

Alternative 2:

The boat may be equipped with an inboard Bukh 10 diesel engine at 10 hp (7 kW). Calculated max speed is about 3.6 knots

The fuel tank has a capacity of 129.0 liters (34 US gallons, 28 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 Master mariner 22 is 1.76, 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 5.8 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 Master mariner 22 is about 100 kg/cm, alternatively 561 lbs/inch.
Meaning: if you load 100 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 561 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 Master mariner 22 is 33.7.

Comparing this ratio with similar sailboats show that it is more comfortable than 100% 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 Master mariner 22 is 2.58.

Compared with other similar sailboats it is more spacy than 82% 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 Master mariner 22 is 40%.

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 Master mariner 22 is 540 which categorizes this boat among 'heavy cruisers'.

0% 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 15m² (161 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.
