When two boats share the same hull type — in this case both the Beneteau Swift Trawler 34 2011 and the Beneteau Swift Trawler 42 2008 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Beneteau Swift Trawler 42 2008 measures 44,0 feet overall (2008), giving it roughly 7,4 additional feet of deck space compared to the Beneteau Swift Trawler 34 2011 at 36,6 feet (2011). Weight tells a clearer story for trailering families: the Beneteau Swift Trawler 34 2011 tips the scales at 16 466 lbs — 16 444 lbs more than the Beneteau Swift Trawler 42 2008 at 22 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 Beneteau Swift Trawler 34 2011 carries a rated maximum of 425 hp. Engine data for the Beneteau Swift Trawler 42 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Beneteau Swift Trawler 42 2008 carries 396 gallons versus 211 gallons in the Beneteau Swift Trawler 34 2011. 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 42 2008 is rated for 13 passengers, while the Beneteau Swift Trawler 34 2011 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 42 2008 could be the deciding factor.
