Dufour Yachts 390 Grand Large 2018 vs Dufour Yachts 412 Grand Large 2016 — Same Brand, Different Boat

The Dufour Yachts 390 Grand Large 2018 vs Dufour Yachts 412 Grand Large 2016 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 390 Grand Large 2018 at 39,2 ft versus Dufour Yachts 412 Grand Large 2016 at 40,6 ft. Weight tells a clearer story for trailering families: the Dufour Yachts 412 Grand Large 2016 tips the scales at 19 709 lbs — 2 733 lbs less than the Dufour Yachts 390 Grand Large 2018 at 16 976 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 — 40 hp for the Dufour Yachts 390 Grand Large 2018 and 40 hp for the Dufour Yachts 412 Grand Large 2016. 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. Both carry nearly identical fuel loads — 53 gal and 53 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Dufour Yachts 412 Grand Large 2016 is rated for 12 passengers, while the Dufour Yachts 390 Grand Large 2018 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Dufour Yachts 412 Grand Large 2016 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 412 Grand Large 2016 displaces 19 709 lbs — a 2 733-lb difference over the Dufour Yachts 390 Grand Large 2018 at 16 976 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 — 6,5 ft and 6,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Dufour Yachts 390 Grand Large 2018 uses Sloop rigging.

Hull speed is rated at 8,1 knots for the Dufour Yachts 412 Grand Large 2016 and 7,9 knots for the Dufour Yachts 390 Grand Large 2018.

Bottom line: The Dufour Yachts 412 Grand Large 2016 is the offshore and bluewater choice — at 19 709 lbs displacement and 41 ft it has the load capacity, range, and seakeeping for extended passages. The Dufour Yachts 390 Grand Large 2018 at 16 976 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.

The Dufour Yachts 412 Grand Large 2016 is the longer of the two at 40,6 feet overall. The Dufour Yachts 390 Grand Large 2018 comes in at 39,2 feet, making it roughly 1,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Dufour Yachts 390 Grand Large 2018 or the Dufour Yachts 412 Grand Large 2016?
For trailering, the Dufour Yachts 390 Grand Large 2018 has the edge at 16 976 lbs dry weight versus 19 709 lbs for the Dufour Yachts 412 Grand Large 2016. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
How many people can each boat hold?
The Dufour Yachts 390 Grand Large 2018 is Coast Guard rated for 11 passengers, while the Dufour Yachts 412 Grand Large 2016 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the deeper draft — the Dufour Yachts 390 Grand Large 2018 or the Dufour Yachts 412 Grand Large 2016?
The Dufour Yachts 390 Grand Large 2018 has the deeper draft at 6,5 ft, versus 6,1 ft for the Dufour Yachts 412 Grand Large 2016. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Dufour Yachts 390 Grand Large 2018 or the Dufour Yachts 412 Grand Large 2016 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Dufour Yachts 412 Grand Large 2016 at 19 709 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Dufour Yachts 390 Grand Large 2018 at 16 976 lbs will typically be livelier and more responsive in lighter conditions.
Which is the faster sailboat — the Dufour Yachts 390 Grand Large 2018 or the Dufour Yachts 412 Grand Large 2016?
Based on rated hull speed, the Dufour Yachts 412 Grand Large 2016 has an edge at 8,1 knots versus 7,9 knots for the Dufour Yachts 390 Grand Large 2018. Keep in mind that actual sailing speed depends heavily on wind conditions, sail trim, bottom condition, and skipper experience — hull speed is a theoretical maximum, not a guarantee.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Dufour Yachts 390 Grand Large 2018 and Dufour Yachts 412 Grand Large 2016 share an 13.10 ft beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Dufour Yachts 390 Grand Large 2018 and Dufour Yachts 412 Grand Large 2016?
Both boats carry similar fuel loads — 53 gallons and 53 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Dufour Yachts 390 Grand Large 2018 and Dufour Yachts 412 Grand Large 2016 from the same manufacturer?
Yes — both the Dufour Yachts 390 Grand Large 2018 and the Dufour Yachts 412 Grand Large 2016 are built by Dufour Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
