The Beneteau First 345 1983 vs Beneteau First Class 7 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 First 345 1983 measures 36,1 feet overall (1983), giving it roughly 14,6 additional feet of deck space compared to the Beneteau First Class 7 1985 at 21,5 feet (1985). Weight tells a clearer story for trailering families: the Beneteau First 345 1983 tips the scales at 11 244 lbs — 9 269 lbs more than the Beneteau First Class 7 1985 at 1 975 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 First 345 1983 carries a rated maximum of 18 hp. Engine data for the Beneteau First Class 7 1985 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Beneteau First 345 1983 is rated for 11 passengers, while the Beneteau First Class 7 1985 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 345 1983 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau First 345 1983 displaces 11 244 lbs — a 9 269-lb difference over the Beneteau First Class 7 1985 at 1 975 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 345 1983 draws 6,2 ft, compared to 4,9 ft for the Beneteau First Class 7 1985. 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.
The Beneteau First 345 1983 is rigged as a fractional_rig_sloop while the Beneteau First Class 7 1985 carries Fractional Sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. The Beneteau First 345 1983 has a documented auxiliary engine of 18 hp.
The Beneteau First Class 7 1985 is trailerable — a genuine advantage for sailors who prefer to keep their boat at home or explore multiple sailing venues.
Bottom line: The Beneteau First 345 1983 is the offshore and bluewater choice — at 11 244 lbs displacement and 36 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First Class 7 1985 at 1 975 lbs is the more nimble, accessible option and is trailerable — easier to single-hand and better suited to coastal and inland sailing.
