The Beneteau Gran Turismo 49 Fly 2013 vs Beneteau Oceanis 31 2007 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 Gran Turismo 49 Fly 2013 measures 51,6 feet overall (2013), giving it roughly 19,8 additional feet of deck space compared to the Beneteau Oceanis 31 2007 at 31,8 feet (2007). Weight tells a clearer story for trailering families: the Beneteau Gran Turismo 49 Fly 2013 tips the scales at 33 038 lbs — 22 346 lbs more than the Beneteau Oceanis 31 2007 at 10 692 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 — 2 hp for the Beneteau Gran Turismo 49 Fly 2013 and 21 hp for the Beneteau Oceanis 31 2007. 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 Gran Turismo 49 Fly 2013 carries 172 gallons versus 34 gallons in the Beneteau Oceanis 31 2007. 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 Oceanis 31 2007 caps at 9. 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.

The Beneteau Oceanis 31 2007 has a documented displacement of 10 692 lbs. Displacement data wasn't available for the other boat in this comparison.

The Beneteau Oceanis 31 2007 has a documented auxiliary engine of 21 hp.

For extended cruising, water capacity matters: the Beneteau Oceanis 31 2007 carries 34 gallons versus 2 gallons on the Beneteau Gran Turismo 49 Fly 2013 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
