Hull

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.


Keel

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 1.20 - 1.30 meter (3.94 - 4.24 ft) dependent on the load. See immersion rate below.


Engine

The boat may be equipped with an inboard diesel 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.
