When two boats share the same hull type — in this case both the Beneteau Flyer Gran Turismo 38 2012 and the Beneteau Swift Trawler 34 2011 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 Flyer Gran Turismo 38 2012 measures 39,7 feet overall (2012), giving it roughly 3,1 additional feet of deck space compared to the Beneteau Swift Trawler 34 2011 at 36,6 feet (2011). At 16 464 lbs and 16 466 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 425 hp, the Beneteau Swift Trawler 34 2011 has a 423-hp advantage over the Beneteau Flyer Gran Turismo 38 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 34 2011 carries 211 gallons versus 172 gallons in the Beneteau Flyer Gran Turismo 38 2012. 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 Flyer Gran Turismo 38 2012 is rated for 12 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 Flyer Gran Turismo 38 2012 could be the deciding factor.
Bottom line: Choose the Beneteau Flyer Gran Turismo 38 2012 if your priority is putting more people on the water — it handles 12 passengers and at 39,7 ft it has the deck room to back that rating up comfortably. The Beneteau Swift Trawler 34 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
