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.
Both the hull and the deck is a sandwich construction which improves the indoor climate. Especially when the water is colder than the air in the cabin, then the double hull insulates against cold water and reduce the condense water in the cabin. The core material in the sandwich construction is balsa.
The boat is equipped with 4 berths and 50.0 liter fresh water capacity.
The Antarès 6.80 has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an outboard Suzuki engine at 115 hp (85 kW). Calculated max speed is about 19.0 knots
Alternative 2:
Antarès 6.80 may be equipped with an outboard Suzuki gasoline engine at 140 hp (104 kW). Calculated max speed is about 20.9 knots
The fuel tank has a capacity of 100.0 liters (26 US gallons, 21 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.
What is Theoretical Maximum Hull Speed?
The theoretical maximal speed of a displacement boat of this length is 5.8 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.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Antarès 6.80 is about 95 kg/cm, alternatively 532 lbs/inch.
Meaning: if you load 95 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 532 lbs cargo on the boat it will sink 1 inch.

Maintenance
As balsa wood is used as sandwich core material special care must be taken in relation to work that require penetration of the sandwich construction in order to to prevent water to get in contact with the balsa wood. Otherwise the balsa wood will eventually rotten and be expensive/impossible to repair.
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 15m2 (161 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.
