The hull is made of fibreglass. A hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 8 berths.
The Comet 13 is built with a masthead rig. The sail area for the mailsail + jib is 74.2 m2 (799.1 ft2). 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.
The Comet 13 has been built with different keel alternatives.
Unknown keel type
The boat can only enter major marinas as the draft is about 1.90 - 2.00 meter (6.23 - 6.53 ft) dependent on the load. See immersion rate below.
Fin keel
The Comet 13 is built with a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
Comet 13 can enter most marinas as the draft is just about 1.60 - 1.70 meter (5.25 - 5.55 ft) dependent on the load. See immersion rate below.
The Comet 13 has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an inboard Volvo Penta diesel engine
Alternative 2:
The boat may be equipped with a diesel engine at 45 hp (33 kW)..
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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Comet 13 is 1.78, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Comet 13 is about 330 kg/cm, alternatively 1853 lbs/inch.
Meaning: if you load 330 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 1853 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 47m2 (505 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.
