The Beneteau Oceanis 321 1994 vs Beneteau Oceanis 400 1997 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 Beneteau Oceanis 400 1997 measures 39,1 feet overall (1997), giving it roughly 6,5 additional feet of deck space compared to the Beneteau Oceanis 321 1994 at 32,6 feet (1994). Weight tells a clearer story for trailering families: the Beneteau Oceanis 400 1997 tips the scales at 16 001 lbs — 6 301 lbs less than the Beneteau Oceanis 321 1994 at 9 700 lbs. 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.

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.

The Beneteau Oceanis 400 1997 draws 5,6 ft, compared to 4,3 ft for the Beneteau Oceanis 321 1994. That 1,3-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.
