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.
The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with one cabin, 4 berths, a galley and toilet facility.
Unknown keel type
The boat can enter even shallow marinas as the draft is just about 0.80 - 0.90 meter (2.62 - 2.92 ft) dependent on the load. See immersion rate below.
Herwa 23 may be equipped with an inboard Albin engine at 25 hp (18 kW). The speed is 6.0 knots.
The fuel tank has a capacity of 50.0 liters (13 US gallons, 10 imperial gallons).
