The Beneteau First 38 1982 vs Beneteau Oceanis 48 2011 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 48 2011 measures 47,1 feet overall (2011), giving it roughly 6,9 additional feet of deck space compared to the Beneteau First 38 1982 at 40,2 feet (1982). Weight tells a clearer story for trailering families: the Beneteau Oceanis 48 2011 tips the scales at 27 765 lbs — 12 112 lbs less than the Beneteau First 38 1982 at 15 653 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.
Both boats share a closely matched power ceiling — 60 hp for the Beneteau First 38 1982 and 75 hp for the Beneteau Oceanis 48 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Beneteau Oceanis 48 2011 carries 53 gallons versus 34 gallons in the Beneteau First 38 1982. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Beneteau Oceanis 48 2011 is rated for 14 passengers, while the Beneteau First 38 1982 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 48 2011 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 48 2011 displaces 27 765 lbs — a 12 112-lb difference over the Beneteau First 38 1982 at 15 653 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.
Both boats draw a similar depth — 6,1 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First 38 1982 uses Sloop rigging. Helm style differs too: the Beneteau First 38 1982 uses a 1 wheel versus a 2 wheels on the Beneteau Oceanis 48 2011. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Oceanis 48 2011 carries a 75-hp engine against 60 hp on the Beneteau First 38 1982. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Hull speed is rated at 9,0 knots for the Beneteau Oceanis 48 2011 and 7,8 knots for the Beneteau First 38 1982.
Bottom line: The Beneteau Oceanis 48 2011 is the offshore and bluewater choice — at 27 765 lbs displacement and 47 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 38 1982 at 15 653 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
