Review of Hallberg-Rassy 41

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.

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 a galley and 560.0 liter fresh water capacity.

The Hallberg-Rassy 41 is equipped with a ketch rig. A ketch rig is generally considered easier to handle, because the sails are smaller, and because it can sail on most points to the wind with one sail completely taken down for repair or while reefing. The sail configuration of a ketch allows for better comfort and stability when sailing downwind or on a broad reach.

Full keel

The boat can only enter major marinas as the draft is about 1.84 - 1.94 meter (6.04 - 6.34 ft) dependent on the load. See immersion rate below.

Hallberg-Rassy 41 may be equipped with an inboard Volvo Penta MD21A diesel engine at 75 hp (55 kW). The speed is 8.5 knots.
