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. 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 deck is a sandwich construction 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 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 2 cabins, 6 berths and 85.0 liter fresh water capacity.
The Karlø 28 has been equipped with different engine alternatives.
Alternative 1:
The boat may be equipped with an inboard Volvo Penta MD21A diesel engine at 75 hp (55 kW). The speed is 16.0 knots.
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.
Alternative 2:
Karlø 28 may be equipped with an inboard Volvo Penta BB-30 diesel engine at 25 hp (18 kW). The speed is 12.0 knots.

Alternative 3:
The boat may be equipped with an inboard Perkins engine at 87 hp (64 kW). The speed is 15.0 knots.
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.
The fuel tank has a capacity of 180.0 liters (47 US gallons, 39 imperial gallons).
