Basic specs.

sail specifications
The Catalina 470 is a large sailboat designed by the maritime architect Gerry Douglas in the late nineties. The Catalina 470 is built by Catalina Yachts.

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

Interior
The boat is equipped with 4+3 berths.

Rig
The boat has more than one rig.

One option is 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 Catalina 470 has been built with more than one type of keel.

One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.But be aware that even though a Fin Keel w/bulb keel is very good for speed racing, a fishing nets and the like in the water can easily make you into a troublesome situation.

Catalina 470 can only enter major marinas as the draft is about 2.39 - 2.49 meter (7.84 - 8.14 ft) dependent on the load. See immersion rate below.


Engine

The boat is typically equipped with an inboard Yanmar 4JH-TE diesel engine at 75.0 hp (55 kW), which gives a max speed about 8.0 knots.

The fuel tank has a capacity of 333.0 liters (87 US gallons, 73 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 Catalina 470 is 1.86, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.


EU classification

Catalina 470 holds one CE certification:

The boat is by European Union certified as Class A. OCEAN:
Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above but excluding abnormal conditions, and vessels largely self-sufficient.


Theoretical Maximum Hull Speed

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 8.7 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 Catalina 470 is about 366 kg/cm, alternatively 2050 lbs/inch.
Meaning: if you load 366 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 2050 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 Catalina 470 is 28.7.

Low High 31% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 31% 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 Catalina 470 is 3.32.

Slim Wide 62% 0 50 100
Compared with other similar sailboats it is more spacy than 62% of all other designs. It seems that the designer has chosen a slightly more spacy hull design.


Ballast Ratio

What is a Ballast Ratio?

The ballast ratio for Catalina 470 is 33%.

Low High 38% 0 50 100
This ballast ratio shows a righting moment that is higher than 38% 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 Catalina 470 is 164 which categorizes this boat among 'light racers'.

Heavy Light 76% 0 50 100
76% 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 Catalina 470 with ISO 8666 reference sail is 17.8, with a 135% genua the SA/D is 20.9.

Low High 38% 0 50 100
The SA/D ratio indicates that it is faster than 38% of all similar sailboat designs in light wind.


Over- / underrigged

Low High 46% 0 50 100
The Catalina 470 has more rig than 46% of all similar sailboats, which indicates that the boat is slightly underrigged.


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 64m2 (688 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.
