The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The hull 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.
Fin keel
The Hallberg-Rassy 45 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 full keel.
The keel is made of lead. Compared with iron, lead has the advantage of being 44% heavier, which allows a smaller keel and hence less water resistance and higher speed.
The boat can only enter major marinas as the draft is about 1.88 - 1.98 meter (6.17 - 6.47 ft) dependent on the load. See immersion rate below.
The boat may be equipped with an inboard Volvo Penta TMD 31A diesel engine at 94 hp (70 kW). The speed is 8.5 knots.
The fuel tank has a capacity of 590.0 liters (155 US gallons, 129 imperial 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.
What is Capsize Screening Formula (CSF)?
The capsize screening value for Hallberg-Rassy 45 is 1.73, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.
The immersion rate is defined as the weight required to sink the boat a certain level.
The immersion rate for Hallberg-Rassy 45 is about 408 kg/cm, alternatively 2288 lbs/inch.
Meaning: if you load 408 kg cargo on the boat then it will sink 1 cm.
Alternatively, if you load 2288 lbs cargo on the boat it will sink 1 inch.
