The Dufour Yachts 1800 1979 vs Dufour Yachts 40e 2010 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 40e 2010 measures 40,6 feet overall (2010), giving it roughly 16,5 additional feet of deck space compared to the Dufour Yachts 1800 1979 at 24,1 feet (1979). Weight tells a clearer story for trailering families: the Dufour Yachts 40e 2010 tips the scales at 18 794 lbs — 13 393 lbs less than the Dufour Yachts 1800 1979 at 5 401 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 40 hp, the Dufour Yachts 40e 2010 has a 32-hp advantage over the Dufour Yachts 1800 1979's 8-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Dufour Yachts 40e 2010 is rated for 12 passengers, while the Dufour Yachts 1800 1979 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Dufour Yachts 40e 2010 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 40e 2010 displaces 18 794 lbs — a 13 393-lb difference over the Dufour Yachts 1800 1979 at 5 401 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 40e 2010 draws 6,1 ft, compared to 4,4 ft for the Dufour Yachts 1800 1979. That 1,7-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 1800 1979 uses Sloop rigging. Helm style differs too: the Dufour Yachts 1800 1979 uses a 1 tiller versus a 2 wheels on the Dufour Yachts 40e 2010. 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 40e 2010 carries a 40-hp engine against 8 hp on the Dufour Yachts 1800 1979. 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 8,0 knots for the Dufour Yachts 40e 2010 and 6,3 knots for the Dufour Yachts 1800 1979. For extended cruising, water capacity matters: the Dufour Yachts 40e 2010 carries 100 gallons versus 25 gallons on the Dufour Yachts 1800 1979 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Dufour Yachts 40e 2010 is the offshore and bluewater choice — at 18 794 lbs displacement and 41 ft it has the load capacity, range, and seakeeping for extended passages. The Dufour Yachts 1800 1979 at 5 401 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
