The Dufour Yachts 3800 1980 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 8,2 additional feet of deck space compared to the Dufour Yachts 3800 1980 at 31,0 feet (1980). Weight tells a clearer story for trailering families: the Dufour Yachts 39 1982 tips the scales at 14 991 lbs — 6 613 lbs less than the Dufour Yachts 3800 1980 at 8 378 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 25-hp advantage over the Dufour Yachts 3800 1980's 18-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 12 gallons in the Dufour Yachts 3800 1980. 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 3800 1980 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 6 613-lb difference over the Dufour Yachts 3800 1980 at 8 378 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 — 5,7 ft and 6,7 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Dufour Yachts 3800 1980 uses Sloop rigging. Helm style differs too: the Dufour Yachts 3800 1980 uses a 1 tiller versus a 1 wheel on the Dufour Yachts 39 1982. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Dufour Yachts 39 1982 carries a 43-hp engine against 18 hp on the Dufour Yachts 3800 1980. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

Hull speed is rated at 7,4 knots for the Dufour Yachts 39 1982 and 6,7 knots for the Dufour Yachts 3800 1980. For extended cruising, water capacity matters: the Dufour Yachts 39 1982 carries 53 gallons versus 32 gallons on the Dufour Yachts 3800 1980 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
