When two boats share the same hull type — in this case both the Beneteau Swift Trawler 34S 2011 and the Beneteau Swift Trawler 52 2012 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 52 2012 measures 55,8 feet overall (2012), giving it roughly 19,2 additional feet of deck space compared to the Beneteau Swift Trawler 34S 2011 at 36,6 feet (2011). Weight tells a clearer story for trailering families: the Beneteau Swift Trawler 34S 2011 tips the scales at 1 603 lbs — 1 601 lbs more than the Beneteau Swift Trawler 52 2012 at 2 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 34S 2011 has a 423-hp advantage over the Beneteau Swift Trawler 52 2012's 2-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 52 2012 carries 1 057 gallons versus 211 gallons in the Beneteau Swift Trawler 34S 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 52 2012 is rated for 16 passengers, while the Beneteau Swift Trawler 34S 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 52 2012 could be the deciding factor.
