Both the hull and the deck 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.
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, 6 berths, a galley, 170.0 liter fresh water capacity, toilet facility and 100.0 liter waste water capacity.
The boat may be equipped with an inboard Volvo Penta TAMD 41B diesel engine at 200 hp (149 kW). Max speed is 23.0 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 has a capacity of 280.0 liters (73 US gallons, 61 imperial gallons).
