The Beneteau First 456 1982 vs Beneteau Oceanis Clipper 423 2008 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 3,6 additional feet of deck space compared to the Beneteau Oceanis Clipper 423 2008 at 43,1 feet (2008). Weight tells a clearer story for trailering families: the Beneteau First 456 1982 tips the scales at 26 455 lbs - 6 955 lbs more than the Beneteau Oceanis Clipper 423 2008 at 19 500 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 - 80 hp for the Beneteau First 456 1982 and 80 hp for the Beneteau Oceanis Clipper 423 2008. 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. Both carry nearly identical fuel loads - 53 gal and 53 gal - so range won't be a tiebreaker here.
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 Clipper 423 2008 caps at 13. 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 6 955-lb difference over the Beneteau Oceanis Clipper 423 2008 at 19 500 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.
Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau First 456 1982 draws 7,1 ft, compared to 5,6 ft for the Beneteau Oceanis Clipper 423 2008. That 1,5-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.
The Beneteau First 456 1982 is rigged as a Sloop while the Beneteau Oceanis Clipper 423 2008 carries Masthead-sloop rigging - a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably.
For extended cruising, water capacity matters: the Beneteau Oceanis Clipper 423 2008 carries 154 gallons versus 106 gallons on the Beneteau First 456 1982 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau First 456 1982 is the offshore and bluewater choice - at 26 455 lbs displacement and 47 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Oceanis Clipper 423 2008 at 19 500 lbs is the more nimble, accessible option - easier to single-hand and better suited to coastal and inland sailing.
