The Beneteau First 21.7 S 2004 vs Beneteau Gran Turismo 49 2013 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 2013 measures 51,6 feet overall (2013), giving it roughly 31,5 additional feet of deck space compared to the Beneteau First 21.7 S 2004 at 20,1 feet (2004). Weight tells a clearer story for trailering families: the Beneteau Gran Turismo 49 2013 tips the scales at 33 038 lbs — 30 294 lbs less than the Beneteau First 21.7 S 2004 at 2 744 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 — 20 hp for the Beneteau First 21.7 S 2004 and 2 hp for the Beneteau Gran Turismo 49 2013. 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 2013 carries 172 gallons versus 8 gallons in the Beneteau First 21.7 S 2004. 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 2013 is rated for 15 passengers, while the Beneteau First 21.7 S 2004 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Gran Turismo 49 2013 could be the deciding factor.
