The Beneteau Swift Trawler 34S 2012 vs Beneteau Swift Trawler 47 2019 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 Swift Trawler 47 2019 measures 48,4 feet overall (2019), giving it roughly 11,8 additional feet of deck space compared to the Beneteau Swift Trawler 34S 2012 at 36,6 feet (2012). Weight tells a clearer story for trailering families: the Beneteau Swift Trawler 47 2019 tips the scales at 27 958 lbs — 26 355 lbs less than the Beneteau Swift Trawler 34S 2012 at 1 603 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 — 425 hp for the Beneteau Swift Trawler 34S 2012 and 425 hp for the Beneteau Swift Trawler 47 2019. 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. Fuel capacity breaks the other way: the Beneteau Swift Trawler 34S 2012 carries 211 gallons versus 51 gallons in the Beneteau Swift Trawler 47 2019. 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 Swift Trawler 47 2019 is rated for 14 passengers, while the Beneteau Swift Trawler 34S 2012 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Swift Trawler 47 2019 could be the deciding factor.
