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 a galley, 260.0 liter fresh water capacity, toilet facility and 100.0 liter waste water capacity.

Engine

The boat may be equipped with an inboard engine

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 420.0 liters (110 US gallons, 92 imperial gallons).
