Dufour Yachts 390 Grand Large 2018 vs Dufour Yachts 45 2008 — Same Brand, Different Boat

The Dufour Yachts 390 Grand Large 2018 vs Dufour Yachts 45 2008 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 45 2008 measures 44,7 feet overall (2008), giving it roughly 5,5 additional feet of deck space compared to the Dufour Yachts 390 Grand Large 2018 at 39,2 feet (2018). Weight tells a clearer story for trailering families: the Dufour Yachts 45 2008 tips the scales at 23 964 lbs — 6 988 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 55 hp for the Dufour Yachts 45 2008. 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. Fuel capacity breaks the other way: the Dufour Yachts 45 2008 carries 66 gallons versus 53 gallons in the Dufour Yachts 390 Grand Large 2018. 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 45 2008 is rated for 13 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 45 2008 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Dufour Yachts 45 2008 displaces 23 964 lbs — a 6 988-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 6,5 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Dufour Yachts 390 Grand Large 2018 uses Sloop rigging. For auxiliary power the Dufour Yachts 45 2008 carries a 55-hp engine against 40 hp on the Dufour Yachts 390 Grand Large 2018. 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 8,5 knots for the Dufour Yachts 45 2008 and 7,9 knots for the Dufour Yachts 390 Grand Large 2018. For extended cruising, water capacity matters: the Dufour Yachts 45 2008 carries 137 gallons versus 100 gallons on the Dufour Yachts 390 Grand Large 2018 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Dufour Yachts 45 2008 is the offshore and bluewater choice — at 23 964 lbs displacement and 45 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.

Dufour Yachts 390 Grand Large 2018 vs Dufour Yachts 45 2008 — Common Questions

Which is the larger boat — the Dufour Yachts 390 Grand Large 2018 or the Dufour Yachts 45 2008?
The Dufour Yachts 45 2008 is the longer of the two at 44,7 feet overall. The Dufour Yachts 390 Grand Large 2018 comes in at 39,2 feet, making it roughly 5,5 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 45 2008?
For trailering, the Dufour Yachts 390 Grand Large 2018 has the edge at 16 976 lbs dry weight versus 23 964 lbs for the Dufour Yachts 45 2008. 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.
Which boat can handle a bigger outboard?
The Dufour Yachts 45 2008 is rated to a maximum of 55 hp, giving it the larger power ceiling. The Dufour Yachts 390 Grand Large 2018 tops out at 40 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
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 45 2008 is certified for 13. 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 45 2008?
The Dufour Yachts 45 2008 has the deeper draft at 6,5 ft, versus 6,5 ft for the Dufour Yachts 390 Grand Large 2018. 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 45 2008 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Dufour Yachts 45 2008 at 23 964 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 45 2008?
Based on rated hull speed, the Dufour Yachts 45 2008 has an edge at 8,5 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.
Which boat is better equipped for long-distance cruising?
For extended passages, fresh water capacity is a key indicator of cruising readiness. The Dufour Yachts 45 2008 carries 137 gallons of fresh water compared to 100 gallons on the Dufour Yachts 390 Grand Large 2018 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Dufour Yachts 45 2008 measures 169" wide, compared to 157" for the Dufour Yachts 390 Grand Large 2018. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Dufour Yachts 390 Grand Large 2018 or the Dufour Yachts 45 2008?
The Dufour Yachts 45 2008 has the bigger tank at 66 gallons, versus 53 gallons on the Dufour Yachts 390 Grand Large 2018. That 13-gallon difference translates to roughly 39–66 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Dufour Yachts 390 Grand Large 2018 and Dufour Yachts 45 2008 from the same manufacturer?
Yes — both the Dufour Yachts 390 Grand Large 2018 and the Dufour Yachts 45 2008 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.
