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.

Engine

An outboard motor is often used on this boat. In that case the boat will typically require a power of 4 - 5 hp, alternatively 82 - 99 lbs thrust if you prefer an electrical motor. Electric outboards are becoming popular for sailboat owners who want clean instant power with less noise and no exhaust fumes.


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 B-32 is 2.57, 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 7.0 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 B-32 is about 176 kg/cm, alternatively 987 lbs/inch.
Meaning: if you load 176 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 987 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 B-32 is 9.8.

Low High 1% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 1% of all similar sailboat designs. This is a comfort value significantly below average.


L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for B-32 is 3.11.

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.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for B-32 is 88 which categorizes this boat among 'ultra light racers'.

Heavy Light 97% 0 50 100
97% 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)?

The SA/D for B-32 with ISO 8666 reference sail is 31.2, with a 135% genua the SA/D is 35.9.

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