The Beneteau First 456 1982 vs Beneteau Oceanis 30.1 2021 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 First 456 1982 measures 46,7 feet overall (1982), giving it roughly 15,3 additional feet of deck space compared to the Beneteau Oceanis 30.1 2021 at 31,4 feet (2021). Weight tells a clearer story for trailering families: the Beneteau First 456 1982 tips the scales at 26 455 lbs — 17 648 lbs more than the Beneteau Oceanis 30.1 2021 at 8 807 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 80 hp, the Beneteau First 456 1982 has a 59-hp advantage over the Beneteau Oceanis 30.1 2021's 21-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 First 456 1982 carries 53 gallons versus 34 gallons in the Beneteau Oceanis 30.1 2021. 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 First 456 1982 is rated for 14 passengers, while the Beneteau Oceanis 30.1 2021 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 456 1982 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau First 456 1982 displaces 26 455 lbs — a 17 648-lb difference over the Beneteau Oceanis 30.1 2021 at 8 807 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 — 7,1 ft and 6,2 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 456 1982 uses Sloop rigging. Helm style differs too: the Beneteau First 456 1982 uses a 1 wheel versus a 1 tiller (helm wheel in option) on the Beneteau Oceanis 30.1 2021. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau First 456 1982 carries a 80-hp engine against 21 hp on the Beneteau Oceanis 30.1 2021. 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 8,4 knots for the Beneteau First 456 1982 and 7,1 knots for the Beneteau Oceanis 30.1 2021. For extended cruising, water capacity matters: the Beneteau First 456 1982 carries 106 gallons versus 42 gallons on the Beneteau Oceanis 30.1 2021 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
