The Dufour Yachts 63 Exclusive 2017 vs Dufour Yachts Lacoste 42 1985 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 63 Exclusive 2017 measures 63,1 feet overall (2017), giving it roughly 20,9 additional feet of deck space compared to the Dufour Yachts Lacoste 42 1985 at 42,2 feet (1985). Weight tells a clearer story for trailering families: the Dufour Yachts 63 Exclusive 2017 tips the scales at 46 720 lbs — 30 185 lbs more than the Dufour Yachts Lacoste 42 1985 at 16 535 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 260 hp, the Dufour Yachts 63 Exclusive 2017 has a 217-hp advantage over the Dufour Yachts Lacoste 42 1985's 43-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 63 Exclusive 2017 carries 219 gallons versus 42 gallons in the Dufour Yachts Lacoste 42 1985. 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 63 Exclusive 2017 is rated for 19 passengers, while the Dufour Yachts Lacoste 42 1985 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Dufour Yachts 63 Exclusive 2017 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 63 Exclusive 2017 displaces 46 720 lbs — a 30 185-lb difference over the Dufour Yachts Lacoste 42 1985 at 16 535 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 63 Exclusive 2017 draws 9,2 ft, compared to 7,6 ft for the Dufour Yachts Lacoste 42 1985. That 1,6-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 63 Exclusive 2017 uses Sloop rigging. Helm style differs too: the Dufour Yachts 63 Exclusive 2017 uses a 2 wheels versus a 1 wheel on the Dufour Yachts Lacoste 42 1985. 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 63 Exclusive 2017 carries a 260-hp engine against 43 hp on the Dufour Yachts Lacoste 42 1985. 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 10,2 knots for the Dufour Yachts 63 Exclusive 2017 and 8,0 knots for the Dufour Yachts Lacoste 42 1985. For extended cruising, water capacity matters: the Dufour Yachts 63 Exclusive 2017 carries 206 gallons versus 106 gallons on the Dufour Yachts Lacoste 42 1985 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
