The Hallberg-Rassy 31 is a true Hallberg-Rassy, with the same high level of quality and elegance as her larger sisters. From model year 2006, production number 307, the boat was modified on thirteen points to the Mark II version.

The interior woodwork and joinery is done in the selected mahogany that has become a Hallberg-Rassy trademark. The interior is extremely well laid out for her size. A full size navigation table, a spacious galley, saloon, large head and shower compartment, and two private staterooms gives you the volume and space that you would normally find on a much larger boat.
