Hull
The hull 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.

Interior
The interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 5-6 berths, a galley and toilet facility.

The boat can enter even shallow marinas as the draft is just about 0.85 - 0.95 meter (2.79 - 3.09 ft) dependent on the load. See immersion rate below.
