The Beneteau First 345 1983 vs Beneteau Oceanis 38.1 2016 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 First 345 1983 at 36,1 ft versus Beneteau Oceanis 38.1 2016 at 38,9 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis 38.1 2016 tips the scales at 15 102 lbs — 3 858 lbs less than the Beneteau First 345 1983 at 11 244 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 40 hp, the Beneteau Oceanis 38.1 2016 has a 22-hp advantage over the Beneteau First 345 1983's 18-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 38.1 2016 carries 34 gallons versus 23 gallons in the Beneteau First 345 1983. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 38.1 2016 displaces 15 102 lbs — a 3 858-lb difference over the Beneteau First 345 1983 at 11 244 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 345 1983 is rigged as a fractional_rig_sloop while the Beneteau Oceanis 38.1 2016 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. Helm style differs too: the Beneteau First 345 1983 uses a 1 tiller versus a 2 wheels on the Beneteau Oceanis 38.1 2016. 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 38.1 2016 carries a 40-hp engine against 18 hp on the Beneteau First 345 1983. 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 38.1 2016 and 7,2 knots for the Beneteau First 345 1983. For extended cruising, water capacity matters: the Beneteau First 345 1983 carries 106 gallons versus 53 gallons on the Beneteau Oceanis 38.1 2016 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
