Beneteau First 40 2008 vs Beneteau First 405 1985 — Same Brand, Different Boat

The Beneteau First 40 2008 vs Beneteau First 405 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.

On paper these two are close siblings in the size department — Beneteau First 40 2008 at 41,4 ft versus Beneteau First 405 1985 at 40,1 ft. Weight tells a clearer story for trailering families: the Beneteau First 405 1985 tips the scales at 18 519 lbs — 1 102 lbs less than the Beneteau First 40 2008 at 17 417 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 Beneteau First 40 2008 and 50 hp for the Beneteau First 405 1985. 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 — 37 gal and 34 gal — so range won't be a tiebreaker here.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Both boats sit in a similar displacement bracket — 17 417 lbs for the Beneteau First 40 2008 and 18 519 lbs for the Beneteau First 405 1985. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Both boats draw a similar depth — 8,0 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 40 2008 is rigged as a fractional_rig_sloop while the Beneteau First 405 1985 carries Sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. For auxiliary power the Beneteau First 405 1985 carries a 50-hp engine against 40 hp on the Beneteau First 40 2008. 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 Beneteau First 405 1985 and 7,9 knots for the Beneteau First 40 2008. For extended cruising, water capacity matters: the Beneteau First 405 1985 carries 106 gallons versus 53 gallons on the Beneteau First 40 2008 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Beneteau First 40 2008 and Beneteau First 405 1985 are closely matched on paper. A sea trial on both in representative conditions is the only reliable way to find which one suits your sailing style, home port, and intended cruising ground.

Beneteau First 40 2008 vs Beneteau First 405 1985 — Common Questions

Which is the larger boat — the Beneteau First 40 2008 or the Beneteau First 405 1985?
The Beneteau First 40 2008 is the longer of the two at 41,4 feet overall. The Beneteau First 405 1985 comes in at 40,1 feet, making it roughly 1,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Beneteau First 40 2008 or the Beneteau First 405 1985?
For trailering, the Beneteau First 40 2008 has the edge at 17 417 lbs dry weight versus 18 519 lbs for the Beneteau First 405 1985. 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 Beneteau First 405 1985 is rated to a maximum of 50 hp, giving it the larger power ceiling. The Beneteau First 40 2008 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 Beneteau First 40 2008 is Coast Guard rated for 12 passengers, while the Beneteau First 405 1985 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 Beneteau First 40 2008 or the Beneteau First 405 1985?
The Beneteau First 40 2008 has the deeper draft at 8,0 ft, versus 7,1 ft for the Beneteau First 405 1985. 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 Beneteau First 40 2008 or the Beneteau First 405 1985 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Beneteau First 405 1985 at 18 519 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Beneteau First 40 2008 at 17 417 lbs will typically be livelier and more responsive in lighter conditions.
Which is the faster sailboat — the Beneteau First 40 2008 or the Beneteau First 405 1985?
Based on rated hull speed, the Beneteau First 405 1985 has an edge at 8,0 knots versus 7,9 knots for the Beneteau First 40 2008. 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 Beneteau First 405 1985 carries 106 gallons of fresh water compared to 53 gallons on the Beneteau First 40 2008 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Beneteau First 405 1985 measures 156" wide, compared to 145" for the Beneteau First 40 2008. 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 Beneteau First 40 2008 or the Beneteau First 405 1985?
The Beneteau First 40 2008 has the bigger tank at 37 gallons, versus 34 gallons on the Beneteau First 405 1985. That 2-gallon difference translates to roughly 6–11 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Beneteau First 40 2008 and Beneteau First 405 1985 from the same manufacturer?
Yes — both the Beneteau First 40 2008 and the Beneteau First 405 1985 are built by Beneteau. 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.
