The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The interior is like many other boats made of mahogany. Mahogany belongs to the hardwood species, known for being water-repellent and resistant to decay. It has an attractive wood grain and holds wood polish and varnish well.
The boat is equipped with 450.0 liter fresh water capacity.
Fin keel
The Hallberg-Rassy 39 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 1.86 - 1.96 meter (6.10 - 6.40 ft) dependent on the load. See immersion rate below.
Hallberg-Rassy 39 may be equipped with an inboard Volvo Penta MD22 diesel engine at 57 hp (42 kW).
The fuel tank has a capacity of 395.0 liters (104 US gallons, 86 imperial gallons).
