The Beneteau Evasion 37 1979 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 3,7 additional feet of deck space compared to the Beneteau Evasion 37 1979 at 37,2 feet (1979). Weight tells a clearer story for trailering families: the Beneteau Evasion 37 1979 tips the scales at 17 637 lbs - 366 lbs more than the Beneteau Oceanis 41.1 2015 at 17 271 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 Evasion 37 1979 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 Evasion 37 1979 carries 66 gallons versus 53 gallons in the Beneteau Oceanis 41.1 2015. 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 Evasion 37 1979 caps at 11. 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.
Both boats sit in a similar displacement bracket - 17 637 lbs for the Beneteau Evasion 37 1979 and 17 271 lbs for the Beneteau Oceanis 41.1 2015. 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 - 7,6 ft and 7,2 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau Evasion 37 1979 is rigged as a Masthead-sloop while the Beneteau Oceanis 41.1 2015 carries Sloop rigging - a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. For auxiliary power the Beneteau Evasion 37 1979 carries a 60-hp engine against 45 hp on the Beneteau Oceanis 41.1 2015. 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 7,5 knots for the Beneteau Evasion 37 1979. For extended cruising, water capacity matters: the Beneteau Evasion 37 1979 carries 132 gallons versus 63 gallons on the Beneteau Oceanis 41.1 2015 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau Oceanis 41.1 2015 at 40,9 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Evasion 37 1979 at 37,2 ft is the easier, lower-cost option - simpler to crew and a strong choice for coastal and day sailing.
