The Beneteau First Class 12 1986 vs Beneteau Oceanis 430 1985 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 430 1985 measures 42,6 feet overall (1985), giving it roughly 3,3 additional feet of deck space compared to the Beneteau First Class 12 1986 at 39,3 feet (1986). Weight tells a clearer story for trailering families: the Beneteau Oceanis 430 1985 tips the scales at 19 842 lbs — 10 362 lbs less than the Beneteau First Class 12 1986 at 9 480 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.
The Beneteau Oceanis 430 1985 tops out at 50 hp. Engine specs for the Beneteau First Class 12 1986 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The Beneteau Oceanis 430 1985 is rated for 12 passengers, while the Beneteau First Class 12 1986 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 430 1985 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 430 1985 displaces 19 842 lbs — a 10 362-lb difference over the Beneteau First Class 12 1986 at 9 480 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 Beneteau First Class 12 1986 draws 6,9 ft, compared to 5,1 ft for the Beneteau Oceanis 430 1985. 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.
The Beneteau Oceanis 430 1985 has a documented auxiliary engine of 50 hp.
Bottom line: The Beneteau Oceanis 430 1985 is the offshore and bluewater choice — at 19 842 lbs displacement and 43 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First Class 12 1986 at 9 480 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
