The Beneteau Gran Turismo 49 Fly 2013 vs Beneteau Oceanis 320 1987 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 20,0 additional feet of deck space compared to the Beneteau Oceanis 320 1987 at 31,6 feet (1987). Weight tells a clearer story for trailering families: the Beneteau Gran Turismo 49 Fly 2013 tips the scales at 33 038 lbs — 24 220 lbs more than the Beneteau Oceanis 320 1987 at 8 818 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 18 hp for the Beneteau Oceanis 320 1987. 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 13 gallons in the Beneteau Oceanis 320 1987. 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 320 1987 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 320 1987 has a documented displacement of 8 818 lbs. Displacement data wasn't available for the other boat in this comparison.

For extended cruising, water capacity matters: the Beneteau Oceanis 320 1987 carries 40 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.
Bottom line: The Beneteau Gran Turismo 49 Fly 2013 at 51,6 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Oceanis 320 1987 at 31,6 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
