The Dufour Yachts 310 Grand Large 2014 vs Dufour Yachts 470 2021 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 470 2021 measures 48,7 feet overall (2021), giving it roughly 16,9 additional feet of deck space compared to the Dufour Yachts 310 Grand Large 2014 at 31,8 feet (2014). Weight tells a clearer story for trailering families: the Dufour Yachts 470 2021 tips the scales at 29 101 lbs — 18 210 lbs less than the Dufour Yachts 310 Grand Large 2014 at 10 891 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 60 hp, the Dufour Yachts 470 2021 has a 41-hp advantage over the Dufour Yachts 310 Grand Large 2014's 19-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 470 2021 carries 66 gallons versus 24 gallons in the Dufour Yachts 310 Grand Large 2014. 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 470 2021 is rated for 14 passengers, while the Dufour Yachts 310 Grand Large 2014 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 470 2021 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 470 2021 displaces 29 101 lbs — a 18 210-lb difference over the Dufour Yachts 310 Grand Large 2014 at 10 891 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 Dufour Yachts 470 2021 draws 7,4 ft, compared to 6,2 ft for the Dufour Yachts 310 Grand Large 2014. That 1,2-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.
The Dufour Yachts 310 Grand Large 2014 uses Sloop rigging. For auxiliary power the Dufour Yachts 470 2021 carries a 60-hp engine against 19 hp on the Dufour Yachts 310 Grand Large 2014. 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 Dufour Yachts 310 Grand Large 2014 carries 42 gallons versus 14 gallons on the Dufour Yachts 470 2021 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Dufour Yachts 470 2021 is the offshore and bluewater choice — at 29 101 lbs displacement and 49 ft it has the load capacity, range, and seakeeping for extended passages. The Dufour Yachts 310 Grand Large 2014 at 10 891 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
