The Dufour Yachts 310 Grand Large 2021 vs Dufour Yachts 3800 1980 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.

On paper these two are close siblings in the size department — Dufour Yachts 310 Grand Large 2021 at 32,0 ft versus Dufour Yachts 3800 1980 at 31,0 ft. Weight tells a clearer story for trailering families: the Dufour Yachts 310 Grand Large 2021 tips the scales at 10 802 lbs — 2 424 lbs more 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.

Both boats share a closely matched power ceiling — 15 hp for the Dufour Yachts 310 Grand Large 2021 and 18 hp for the Dufour Yachts 3800 1980. 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 Dufour Yachts 310 Grand Large 2021 carries 24 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.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 310 Grand Large 2021 displaces 10 802 lbs — a 2 424-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 — 6,2 ft and 5,7 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

Sailboat comparisons often come down to details that specs don't fully capture — the quality of the standing rigging, the layout of the cockpit, and how the boat feels on a beat in 20 knots. A sea trial on both is strongly recommended.

For extended cruising, water capacity matters: the Dufour Yachts 310 Grand Large 2021 carries 48 gallons versus 32 gallons on the Dufour Yachts 3800 1980 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
