Hull

The hull is made of hand laid fibreglass while the deck is made of fibreglass. Generally, a hull made of hand laid 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.
The deck is a double deck which improves the indoor climate.

Interior

The interior is like most other boats made of teak. Teak has the advantage of being naturally very oily and therefore water-repellent, which is suitable on boats.
The boat is equipped with 2 cabins, 7 berths, a galley, 200.0 liter fresh water capacity, toilet facility and 70.0 liter waste water capacity.

Engine

The boat is typically equipped with an inboard Yanmar diesel engine at 180 hp (134 kW). Cruise speed is 16.0 knots. Max speed is 21.0 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.

The fuel tank, which is made of fibreglass, has a capacity of 200.0 liters (52 US gallons, 43 imperial gallons).

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.

The boat is by European Union certified as Class C. INSHORE:

Designed for voyages in coastal waters, large bays, estuaries, lakes and rivers where conditions up to, and including, wind force 6 (Beaufort scale) and significant wave heights up to, and including, 2 m may be experienced.

Immersion rate

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Agder 840 is about 180 kg/cm, alternatively 1008 lbs/inch.
Meaning: if you load 180 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1008 lbs cargo on the boat it will sink 1 inch.
