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.
The hull is a double hull 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 deck is a double deck which improves the indoor climate.

Interior

The boat is equipped with 2 cabins, 5 berths, a galley, 200.0 liter fresh water capacity, toilet facility and 80.0 liter waste water capacity.
