The Beneteau First 31.7 1997 vs Beneteau Oceanis 38 2013 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 38 2013 measures 37,8 feet overall (2013), giving it roughly 6,2 additional feet of deck space compared to the Beneteau First 31.7 1997 at 31,6 feet (1997). Weight tells a clearer story for trailering families: the Beneteau Oceanis 38 2013 tips the scales at 15 102 lbs — 6 835 lbs less than the Beneteau First 31.7 1997 at 8 267 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 — 21 hp for the Beneteau First 31.7 1997 and 30 hp for the Beneteau Oceanis 38 2013. 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 38 2013 carries 34 gallons versus 8 gallons in the Beneteau First 31.7 1997. 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 38 2013 is rated for 11 passengers, while the Beneteau First 31.7 1997 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 38 2013 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 38 2013 displaces 15 102 lbs — a 6 835-lb difference over the Beneteau First 31.7 1997 at 8 267 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 — 6,2 ft and 6,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First 31.7 1997 uses Sloop rigging. Helm style differs too: the Beneteau First 31.7 1997 uses a 1 tiller versus a 2 wheels on the Beneteau Oceanis 38 2013. 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 38 2013 carries a 30-hp engine against 21 hp on the Beneteau First 31.7 1997. 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 8,0 knots for the Beneteau Oceanis 38 2013 and 7,2 knots for the Beneteau First 31.7 1997.
Bottom line: The Beneteau Oceanis 38 2013 is the offshore and bluewater choice — at 15 102 lbs displacement and 38 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau First 31.7 1997 at 8 267 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
