The Beneteau First 35S5 1988 vs Beneteau Oceanis 41.1 2015 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 41.1 2015 measures 40,9 feet overall (2015), giving it roughly 5,4 additional feet of deck space compared to the Beneteau First 35S5 1988 at 35,5 feet (1988). Weight tells a clearer story for trailering families: the Beneteau Oceanis 41.1 2015 tips the scales at 17 271 lbs — 5 807 lbs less than the Beneteau First 35S5 1988 at 11 464 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 — 28 hp for the Beneteau First 35S5 1988 and 45 hp for the Beneteau Oceanis 41.1 2015. 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 41.1 2015 carries 53 gallons versus 19 gallons in the Beneteau First 35S5 1988. 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 41.1 2015 is rated for 12 passengers, while the Beneteau First 35S5 1988 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 41.1 2015 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 41.1 2015 displaces 17 271 lbs — a 5 807-lb difference over the Beneteau First 35S5 1988 at 11 464 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 Oceanis 41.1 2015 draws 7,2 ft, compared to 5,1 ft for the Beneteau First 35S5 1988. That 2,1-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 35S5 1988 uses Sloop rigging. Helm style differs too: the Beneteau First 35S5 1988 uses a 1 tiller versus a 2 wheels on the Beneteau Oceanis 41.1 2015. 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 41.1 2015 carries a 45-hp engine against 28 hp on the Beneteau First 35S5 1988. 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 8,2 knots for the Beneteau Oceanis 41.1 2015 and 7,3 knots for the Beneteau First 35S5 1988.
Bottom line: The Beneteau Oceanis 41.1 2015 is the offshore and bluewater choice — at 17 271 lbs displacement and 41 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 35S5 1988 at 11 464 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
