The Beneteau First 456 1982 vs Beneteau Swift Trawler 34 2013 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 10,7 additional feet of deck space compared to the Beneteau Swift Trawler 34 2013 at 36,0 feet (2013). Weight tells a clearer story for trailering families: the Beneteau First 456 1982 tips the scales at 26 455 lbs — 24 813 lbs more than the Beneteau Swift Trawler 34 2013 at 1 642 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 425 hp, the Beneteau Swift Trawler 34 2013 has a 345-hp advantage over the Beneteau First 456 1982's 80-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 Swift Trawler 34 2013 carries 211 gallons versus 53 gallons in the Beneteau First 456 1982. 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 Swift Trawler 34 2013 caps at 10. 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.
