690 UNITS IN FIFTEEN YEARS 1979-1993

The Hallberg-Rassy 312 was built for fifteen years between 1979 and 1993. Totally 690 boats were built. The HR 312 is a very popular model. Until 1986 the Hallberg-Rassy 312 Mark I was built, with the portlights in the blue stripe in the hull and with or without quarter berth. Models without quarter berth had an extra cockpit locker on starboard.

UPDATED TO MARK II IN 1986

In 1986 the Hallberg-Rassy 312 Mk II was introduced. The first visible change is that the portlights got larger and were moved up to the superstructure as on today’s Hallberg-Rassy range. This gives a brighter saloon and a greater feeling of spaciousness. The whole superstructure and cockpit was at the same time moved aft, allowing a couple of important extra centimetres in the saloon. The superstructure was also raised, improving the headroom from 1.83 m to 1.85 m, which subjectively feels a lot more than the figure suggests on the paper. The working area of the galley was improved. The newer model was only built with quarter berth. The toilet compartment also got separate, and not all over the beam of the boat as on the previous model. There was a shower basin fitted into the new toilet compartment.
