The Dufour Yachts 310 Grand Large 2014 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 2014 at 31,8 ft versus Dufour Yachts 3800 1980 at 31,0 ft. Weight tells a clearer story for trailering families: the Dufour Yachts 310 Grand Large 2014 tips the scales at 10 891 lbs — 2 513 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 — 19 hp for the Dufour Yachts 310 Grand Large 2014 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 2014 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.

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.
