Both the hull and the deck is made of fibreglass. 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 boat is equipped with 2+2 berths, a galley and 60 liters (15 US gallons, 13 imperial gallons) fresh water capacity.
The headroom is above average
Full keel
The Viksund Columbi 27 is built with a long keel. A long keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.
The boat can enter even shallow marinas as the draft is just about 1.10 - 1.20 meter (3.61 - 3.91 ft) dependent on the load. See immersion rate below.
The fuel tank, which is made of plastic, has a capacity of 80 liters (21 US gallons, 17 imperial gallons).
The Viksund Columbi 27 has been equipped with different engine alternatives.
Alternative 1:
Viksund Columbi 27 may be equipped with an inboard Volvo Penta MD2 diesel engine at 16 hp (11 kW).
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:
The boat may be equipped with an inboard Volvo Penta D1-30F diesel engine at 30 hp (22 kW). Cruise speed is 6.0 knots. Max speed is 7.0 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 3:
The boat may be equipped with an inboard Leyland BMC 1800 diesel engine at 48 hp (35 kW).
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.
Sailing characteristics
This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Viksund Columbi 27 is about 153 kg/cm, alternatively 860 lbs/inch.
Meaning: if you load 153 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 860 lbs cargo on the boat it will sink 1 inch.

Maintenance
When buying anti-fouling bottom paint, it's nice to know how much to buy.
The surface of the wet bottom is about 20m2 (215 ft2).
Based on this, your favourite maritime shop can tell you the quantity you need.
Note: If you use a paint roller you will need more paint than if you use a paintbrush.
