Basic specs.

sail specifications
The Comet 28 Race is a sailboat designed by the French maritime architect bureau Groupe Finot in the mid eighties. Less than 100 boats have been produced. The Comet 28 Race is built by the Italian yard Comar Yachts.

Here we would have liked to show you nice photos of the Comet 28 Race.

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.


Interior

The boat is equipped with 42.0 liter fresh water capacity.


Rig

The Comet 28 Race 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

Fin keel

The Comet 28 Race is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel.

The boat can enter most marinas as the draft is just about 1.50 - 1.60 meter (4.92 - 5.22 ft) dependent on the load. See immersion rate below.


Engine

Comet 28 Race may be equipped with an inboard Nanni diesel engine

The fuel tank has a capacity of 4.0 liters (1 US gallons, 0 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 Comet 28 Race is 2.10, 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 6.6 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 Comet 28 Race is about 122 kg/cm, alternatively 686 lbs/inch.
Meaning: if you load 122 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 686 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 Comet 28 Race is 13.9.

Low High 12% 0 50 100
Comparing this ratio with similar sailboats show that it is more comfortable than 12% 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 Comet 28 Race is 3.45.

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.


D/L (Displacement Length Ratio)

What is Displacement Length Ratio?

The DL-ratio for Comet 28 Race is 120 which categorizes this boat among 'ultra light racers'.

Heavy Light 93% 0 50 100
93% 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 Comet 28 Race with ISO 8666 reference sail is 19.8, with a 135% genua the SA/D is 23.3.

Low High 88% 0 50 100
The SA/D ratio indicates that it is faster than 88% of all similar sailboat designs in light wind.


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 22m2 (236 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.
