The Hallberg - Rassy 382 1984 vs Hallberg - Rassy 48 2004 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Hallberg - Rassy 48 2004 measures 49,2 feet overall (2004), giving it roughly 11,1 additional feet of deck space compared to the Hallberg - Rassy 382 1984 at 38,1 feet (1984).

That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 110 hp, the Hallberg - Rassy 48 2004 has a 48-hp advantage over the Hallberg - Rassy 382 1984's 62-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Hallberg - Rassy 48 2004 carries 212 gallons versus 89 gallons in the Hallberg - Rassy 382 1984. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Hallberg - Rassy 48 2004 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Hallberg - Rassy 48 2004 displaces 40 700 lbs — a 20 858-lb difference over the Hallberg - Rassy 382 1984 at 19 842 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Hallberg - Rassy 48 2004 draws 7,8 ft, compared to 6,0 ft for the Hallberg - Rassy 382 1984. That 1,8-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Hallberg - Rassy 48 2004 carries 241 gallons versus 153 gallons on the Hallberg - Rassy 382 1984 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
