Basic specs.

boat specifications
The Blue Dane 32 is a sailboat designed by the Danish maritime architect bureau Elvstrøm & Kjærulff together with Svend Aage Christensen from in the mid seventies. The Blue Dane 32 is built by the Danish yard Bianca A/S.

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. 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 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
Interior
Interior of Blue Dane 32 anno 1979
The interior is like many other boats made of mahogany.
The boat is equipped with 2 cabins, 6 berths, a galley and toilet facility.

Rig

Keel
The boat has a fin keel which means that it is more manoeuvrable but has less directional stability than a similar boat with a long keel. The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allow a minor keel and hence less water resistance and higher speed. Blue Dane 32 can enter most marinas as the draft is just about 1.70 - 1.80 meter (5.58 - 5.88 ft) dependent on the load. See immersion rate below.

Engine
The boat is typical equipped with an inboard engine.
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 has a capacity of 50 liters (13 US gallons).

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.

Stability and Safety
What is Capsize Screening Formula (CSF)?
The capsize screening value for Blue Dane 32 is 2.03, indicating that this boat would not be accepted to participate in ocean races.

Immersion rate
The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Blue Dane 32 is about 193 kg/cm, alternative 1082 lbs/inch.
Meaning: if you load 193 kg cargo on the boat then it will sink 1 cm. Alternative, if you load 1082 lbs cargo on the boat it will sink 1 inch.
