The Dufour Yachts 520 Grand Large 2017 vs Dufour Yachts 530 2020 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 530 2020 measures 53,7 feet overall (2020), giving it roughly 4,6 additional feet of deck space compared to the Dufour Yachts 520 Grand Large 2017 at 49,1 feet (2017). Weight tells a clearer story for trailering families: the Dufour Yachts 530 2020 tips the scales at 35 920 lbs — 2 311 lbs less than the Dufour Yachts 520 Grand Large 2017 at 33 609 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 110 hp, the Dufour Yachts 530 2020 has a 35-hp advantage over the Dufour Yachts 520 Grand Large 2017's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 119 gal and 116 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Dufour Yachts 530 2020 is rated for 16 passengers, while the Dufour Yachts 520 Grand Large 2017 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Dufour Yachts 530 2020 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 530 2020 displaces 35 920 lbs — a 2 311-lb difference over the Dufour Yachts 520 Grand Large 2017 at 33 609 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 — 7,6 ft and 7,6 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Dufour Yachts 520 Grand Large 2017 uses Sloop rigging. For auxiliary power the Dufour Yachts 530 2020 carries a 110-hp engine against 75 hp on the Dufour Yachts 520 Grand Large 2017. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

Bottom line: The Dufour Yachts 530 2020 is the offshore and bluewater choice — at 35 920 lbs displacement and 54 ft it has the load capacity, range, and seakeeping for extended passages. The Dufour Yachts 520 Grand Large 2017 at 33 609 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
