The Beneteau Gran Turismo 49 2020 vs Beneteau R/C 42 1981 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 2020 measures 51,7 feet overall (2020), giving it roughly 8,3 additional feet of deck space compared to the Beneteau R/C 42 1981 at 43,4 feet (1981). Weight tells a clearer story for trailering families: the Beneteau Gran Turismo 49 2020 tips the scales at 33 038 lbs — 10 661 lbs more than the Beneteau R/C 42 1981 at 22 377 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 435 hp, the Beneteau Gran Turismo 49 2020 has a 385-hp advantage over the Beneteau R/C 42 1981's 50-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 49 2020 carries 172 gallons versus 40 gallons in the Beneteau R/C 42 1981. 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 2020 is rated for 15 passengers, while the Beneteau R/C 42 1981 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Gran Turismo 49 2020 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau Gran Turismo 49 2020 displaces 33 038 lbs — a 10 661-lb difference over the Beneteau R/C 42 1981 at 22 377 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau R/C 42 1981 draws 5,7 ft, compared to 3,6 ft for the Beneteau Gran Turismo 49 2020. That 2,1-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

For auxiliary power the Beneteau Gran Turismo 49 2020 carries a 435-hp engine against 50 hp on the Beneteau R/C 42 1981. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

For extended cruising, water capacity matters: the Beneteau R/C 42 1981 carries 106 gallons versus 85 gallons on the Beneteau Gran Turismo 49 2020 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
