The Beneteau First 35S5 1988 vs Beneteau Oceanis 320 1987 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 35S5 1988 measures 35,5 feet overall (1988), giving it roughly 3,9 additional feet of deck space compared to the Beneteau Oceanis 320 1987 at 31,6 feet (1987). Weight tells a clearer story for trailering families: the Beneteau First 35S5 1988 tips the scales at 11 464 lbs — 2 646 lbs more than the Beneteau Oceanis 320 1987 at 8 818 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 18 hp for the Beneteau Oceanis 320 1987. 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 First 35S5 1988 carries 19 gallons versus 13 gallons in the Beneteau Oceanis 320 1987. 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 First 35S5 1988 is rated for 10 passengers, while the Beneteau Oceanis 320 1987 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 35S5 1988 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau First 35S5 1988 displaces 11 464 lbs — a 2 646-lb difference over the Beneteau Oceanis 320 1987 at 8 818 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 — 5,1 ft and 4,7 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First 35S5 1988 uses Sloop rigging. For auxiliary power the Beneteau First 35S5 1988 carries a 28-hp engine against 18 hp on the Beneteau Oceanis 320 1987. 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 7,3 knots for the Beneteau First 35S5 1988 and 7,1 knots for the Beneteau Oceanis 320 1987. For extended cruising, water capacity matters: the Beneteau First 35S5 1988 carries 69 gallons versus 40 gallons on the Beneteau Oceanis 320 1987 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau First 35S5 1988 is the offshore and bluewater choice — at 11 464 lbs displacement and 36 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Oceanis 320 1987 at 8 818 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
