Review of Belliure 40

Basic specs.

The Belliure 40 is a large sailboat designed by the Spanish maritime architect Peter A. Ibold together with Vicente Belliure also from Spain in the early eighties. The Belliure 40 is built by the Spanish yard Belliure S. A..

Hull

The hull is made of fibreglass. A hull made of fibreglass requires only a minimum of maintenance during the sailing season.

Interior

Floor plan of Belliure 40.

The boat is equipped with 3 cabins, 6-9 berths, 795 liters (210 US gallons, 174 imperial gallons) fresh water capacity and toilet facility.

Rig

The Belliure 40 is built 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

Keel of Belliure 40.

The Belliure 40 has been built with different keel alternatives.

Unknown keel type

The boat can only enter major marinas as the draft is about 1.80 - 1.90 meter (5.91 - 6.21 ft) dependent on the load. See immersion rate below.

Unknown keel type

Belliure 40 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 fuel tank has a capacity of 500 liters (132 US gallons, 109 imperial gallons).

The boat may be equipped with an inboard Volvo Penta diesel engine at 67 hp (49 kW). Calculated max speed is about 7.5 knots

The transmission is a shaft drive. A shaft drive will in the long run require less maintenance than other types of drive e.g. a sail drive.

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 Belliure 40 is 1.91, 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 7.5 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 Belliure 40 is about 254 kg/cm, alternatively 1425 lbs/inch.
Meaning: if you load 254 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1425 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 Belliure 40 is 30.5.

Comparing this ratio with similar sailboats show that it is more comfortable than 54% of all similar sailboat designs. This comfort value is just above average.

L/B (Length Beam Ratio)

What is L/B (Length Beam Ratio)?

The l/b ratio for Belliure 40 is 3.05.

Compared with other similar sailboats it is more spacy than 76% 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 Belliure 40 is 306 which categorizes this boat among 'heavy cruisers'.

31% 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.

SA/D (Sail Area Displacement ratio)

SA/D (Sail Area Displacement ratio)
Indicates how fast the boat is in light wind:
- Cruising Boats have ratios 10-15
- Cruiser-Racers have ratios 16-20
- Racers have ratios above 20
- High-Performance Racers have ratios above 24
Sail-area/displacement ratio (SA/D ratio): 16.20

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 41m² (441 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

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.
