Hull

Both the hull and the deck is made of hand laid fibreglass. Generally, a hull made of hand laid 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 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 3 cabins, 6 berths, a galley, toilet facility and 102 liter waste water capacity.

Engine

The boat is typically equipped with dual inboard diesel engines at 660.0 hp (491 kW).

The transmission is a shaft drive.

The fuel tank which is made of stainless steel has a capacity of 776 liters (204 US gallons, 170 imperial gallons).
