The Beneteau Evasion 28 1975 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 Oceanis 320 1987 measures 31,6 feet overall (1987), giving it roughly 4,5 additional feet of deck space compared to the Beneteau Evasion 28 1975 at 27,1 feet (1975). Weight tells a clearer story for trailering families: the Beneteau Evasion 28 1975 tips the scales at 9 480 lbs — 662 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 — 30 hp for the Beneteau Evasion 28 1975 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 Evasion 28 1975 carries 24 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 Oceanis 320 1987 is rated for 9 passengers, while the Beneteau Evasion 28 1975 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 320 1987 could be the deciding factor.
Both boats sit in a similar displacement bracket — 9 480 lbs for the Beneteau Evasion 28 1975 and 8 818 lbs for the Beneteau Oceanis 320 1987. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.
Both boats draw a similar depth — 4,1 ft and 4,7 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau Evasion 28 1975 uses Sloop rigging. Helm style differs too: the Beneteau Evasion 28 1975 uses a 1 wheel versus a 1 tiller on the Beneteau Oceanis 320 1987. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Evasion 28 1975 carries a 30-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 7,1 knots for the Beneteau Oceanis 320 1987 and 6,2 knots for the Beneteau Evasion 28 1975. For extended cruising, water capacity matters: the Beneteau Evasion 28 1975 carries 53 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 Oceanis 320 1987 at 31,6 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Evasion 28 1975 at 27,1 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
