The Dufour Yachts 310 Grand Large 2021 vs Dufour Yachts 39 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 Dufour Yachts 39 1982 measures 39,2 feet overall (1982), giving it roughly 7,2 additional feet of deck space compared to the Dufour Yachts 310 Grand Large 2021 at 32,0 feet (2021). Weight tells a clearer story for trailering families: the Dufour Yachts 39 1982 tips the scales at 14 991 lbs — 4 189 lbs less than the Dufour Yachts 310 Grand Large 2021 at 10 802 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 43 hp, the Dufour Yachts 39 1982 has a 28-hp advantage over the Dufour Yachts 310 Grand Large 2021's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Dufour Yachts 39 1982 carries 29 gallons versus 24 gallons in the Dufour Yachts 310 Grand Large 2021. 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 Dufour Yachts 39 1982 is rated for 11 passengers, while the Dufour Yachts 310 Grand Large 2021 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Dufour Yachts 39 1982 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 39 1982 displaces 14 991 lbs — a 4 189-lb difference over the Dufour Yachts 310 Grand Large 2021 at 10 802 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.
Both boats draw a similar depth — 6,2 ft and 6,7 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
For auxiliary power the Dufour Yachts 39 1982 carries a 43-hp engine against 15 hp on the Dufour Yachts 310 Grand Large 2021. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Bottom line: The Dufour Yachts 39 1982 is the offshore and bluewater choice — at 14 991 lbs displacement and 39 ft it has the load capacity, range, and seakeeping for extended passages. The Dufour Yachts 310 Grand Large 2021 at 10 802 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
