The Beneteau First 45 2007 vs Beneteau First 456 1982 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 45 2007 at 46,2 ft versus Beneteau First 456 1982 at 46,7 ft. Weight tells a clearer story for trailering families: the Beneteau First 456 1982 tips the scales at 26 455 lbs — 970 lbs less than the Beneteau First 45 2007 at 25 485 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 26-hp advantage over the Beneteau First 45 2007's 54-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 53 gal and 53 gal — so range won't be a tiebreaker here.

Both boats are rated for 14 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.

Both boats sit in a similar displacement bracket — 25 485 lbs for the Beneteau First 45 2007 and 26 455 lbs for the Beneteau First 456 1982. 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 — 7,1 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 45 2007 uses Sloop rigging. Helm style differs too: the Beneteau First 45 2007 uses a 2 wheels versus a 1 wheel on the Beneteau First 456 1982. 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 54 hp on the Beneteau First 45 2007. 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 8,4 knots for the Beneteau First 45 2007. For extended cruising, water capacity matters: the Beneteau First 45 2007 carries 151 gallons versus 106 gallons on the Beneteau First 456 1982 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
