Hull

Both the hull and the deck 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.

Note: the boat has also been sold to be self-made/-interiored, which means that the quality of each boat may vary.

Rig

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

Keel

The Bandholm 27 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.

Bandholm 27 can enter even shallow marinas as the draft is just about 1.45 - 1.55 meter (4.76 - 5.06 ft) dependent on the load. See immersion rate below.

Engine

The boat is typically equipped with an inboard Bukh DV10 diesel engine at 10.0 hp (7 kW), which gives a max speed about 4.4 knots.

The transmission is a shaft drive. A shaft drive will in the long run require less maintenence than other types of drive *e.g.* a sail drive.

The fuel tank which is made of fibreglass has a capacity of 60.0 liters (15 US gallons, 13 imperial gallons).

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.
