When two boats share the same hull type — in this case both the Beneteau Gran Turismo 49 Fly 2013 and the Beneteau Swift Trawler 34S 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 Gran Turismo 49 Fly 2013 measures 51,6 feet overall (2013), giving it roughly 15,0 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 Gran Turismo 49 Fly 2013 tips the scales at 33 038 lbs — 31 435 lbs more 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.

The power gap is worth calling out. Rated to 425 hp, the Beneteau Swift Trawler 34S 2012 has a 423-hp advantage over the Beneteau Gran Turismo 49 Fly 2013'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 34S 2012 carries 211 gallons versus 172 gallons in the Beneteau Gran Turismo 49 Fly 2013. 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 Gran Turismo 49 Fly 2013 is rated for 15 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 Gran Turismo 49 Fly 2013 could be the deciding factor.
