The Beneteau Gran Turismo 38 2013 vs Beneteau Idylle 8.80 1982 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 38 2013 measures 39,7 feet overall (2013), giving it roughly 11,6 additional feet of deck space compared to the Beneteau Idylle 8.80 1982 at 28,1 feet (1982). Weight tells a clearer story for trailering families: the Beneteau Gran Turismo 38 2013 tips the scales at 16 199 lbs — 8 814 lbs more than the Beneteau Idylle 8.80 1982 at 7 385 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 30 hp, the Beneteau Idylle 8.80 1982 has a 28-hp advantage over the Beneteau Gran Turismo 38 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 Gran Turismo 38 2013 carries 172 gallons versus 21 gallons in the Beneteau Idylle 8.80 1982. 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 38 2013 is rated for 11 passengers, while the Beneteau Idylle 8.80 1982 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Gran Turismo 38 2013 could be the deciding factor.
