The Beneteau Oceanis 34.1 2014 vs Beneteau Oceanis 390 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 390 1987 measures 38,2 feet overall (1987), giving it roughly 4,3 additional feet of deck space compared to the Beneteau Oceanis 34.1 2014 at 33,9 feet (2014). Weight tells a clearer story for trailering families: the Beneteau Oceanis 390 1987 tips the scales at 14 330 lbs — 1 941 lbs less than the Beneteau Oceanis 34.1 2014 at 12 389 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.

The power gap is worth calling out. Rated to 50 hp, the Beneteau Oceanis 390 1987 has a 21-hp advantage over the Beneteau Oceanis 34.1 2014's 29-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau Oceanis 390 1987 carries 46 gallons versus 34 gallons in the Beneteau Oceanis 34.1 2014. 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 390 1987 is rated for 11 passengers, while the Beneteau Oceanis 34.1 2014 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 390 1987 could be the deciding factor.

Both boats sit in a similar displacement bracket — 12 389 lbs for the Beneteau Oceanis 34.1 2014 and 14 330 lbs for the Beneteau Oceanis 390 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 — 6,0 ft and 5,5 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

For auxiliary power the Beneteau Oceanis 390 1987 carries a 50-hp engine against 29 hp on the Beneteau Oceanis 34.1 2014. 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 390 1987 carries 169 gallons versus 77 gallons on the Beneteau Oceanis 34.1 2014 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
