The Beneteau Oceanis 38 2013 vs Beneteau Oceanis 40 2014 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.
On paper these two are close siblings in the size department - Beneteau Oceanis 38 2013 at 37,8 ft versus Beneteau Oceanis 40 2014 at 40,0 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis 40 2014 tips the scales at 16 931 lbs - 1 829 lbs less than the Beneteau Oceanis 38 2013 at 15 102 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 Oceanis 38 2013 and 40 hp for the Beneteau Oceanis 40 2014. 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 40 2014 carries 53 gallons versus 34 gallons in the Beneteau Oceanis 38 2013. 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 40 2014 is rated for 12 passengers, while the Beneteau Oceanis 38 2013 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 40 2014 could be the deciding factor.
Both boats sit in a similar displacement bracket - 15 102 lbs for the Beneteau Oceanis 38 2013 and 16 931 lbs for the Beneteau Oceanis 40 2014. 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 - 6,1 ft and 6,4 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau Oceanis 38 2013 uses Sloop rigging. For auxiliary power the Beneteau Oceanis 40 2014 carries a 40-hp engine against 30 hp on the Beneteau Oceanis 38 2013. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Beneteau Oceanis 40 2014 carries 95 gallons versus 34 gallons on the Beneteau Oceanis 38 2013 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau Oceanis 40 2014 at 40,0 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Oceanis 38 2013 at 37,8 ft is the easier, lower-cost option - simpler to crew and a strong choice for coastal and day sailing.
