Beneteau Idylle 11.50 Fin keel 1983 vs Beneteau Oceanis 46.1 2022 — Same Brand, Different Boat

The Beneteau Idylle 11.50 Fin keel 1983 vs Beneteau Oceanis 46.1 2022 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 Beneteau Oceanis 46.1 2022 measures 47,1 feet overall (2022), giving it roughly 9,3 additional feet of deck space compared to the Beneteau Idylle 11.50 Fin keel 1983 at 37,8 feet (1983). Weight tells a clearer story for trailering families: the Beneteau Oceanis 46.1 2022 tips the scales at 23 356 lbs — 11 892 lbs less than the Beneteau Idylle 11.50 Fin keel 1983 at 11 464 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 80 hp, the Beneteau Oceanis 46.1 2022 has a 30-hp advantage over the Beneteau Idylle 11.50 Fin keel 1983's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau Oceanis 46.1 2022 carries 53 gallons versus 21 gallons in the Beneteau Idylle 11.50 Fin keel 1983. 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 Beneteau Oceanis 46.1 2022 is rated for 14 passengers, while the Beneteau Idylle 11.50 Fin keel 1983 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 46.1 2022 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 46.1 2022 displaces 23 356 lbs — a 11 892-lb difference over the Beneteau Idylle 11.50 Fin keel 1983 at 11 464 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 Beneteau Oceanis 46.1 2022 draws 8,8 ft, compared to 4,5 ft for the Beneteau Idylle 11.50 Fin keel 1983. That 4,3-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 Beneteau Idylle 11.50 Fin keel 1983 is rigged as a Sloop while the Beneteau Oceanis 46.1 2022 carries fractional_rig_sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. Helm style differs too: the Beneteau Idylle 11.50 Fin keel 1983 uses a 1 wheel versus a 2 wheels on the Beneteau Oceanis 46.1 2022. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Oceanis 46.1 2022 carries a 80-hp engine against 50 hp on the Beneteau Idylle 11.50 Fin keel 1983. 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 8,8 knots for the Beneteau Oceanis 46.1 2022 and 7,2 knots for the Beneteau Idylle 11.50 Fin keel 1983.

Bottom line: The Beneteau Oceanis 46.1 2022 is the offshore and bluewater choice — at 23 356 lbs displacement and 47 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Idylle 11.50 Fin keel 1983 at 11 464 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.

Beneteau Idylle 11.50 Fin keel 1983 vs Beneteau Oceanis 46.1 2022 — Common Questions

Which is the larger boat — the Beneteau Idylle 11.50 Fin keel 1983 or the Beneteau Oceanis 46.1 2022?
The Beneteau Oceanis 46.1 2022 is the longer of the two at 47,1 feet overall. The Beneteau Idylle 11.50 Fin keel 1983 comes in at 37,8 feet, making it roughly 9,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Beneteau Idylle 11.50 Fin keel 1983 or the Beneteau Oceanis 46.1 2022?
For trailering, the Beneteau Idylle 11.50 Fin keel 1983 has the edge at 11 464 lbs dry weight versus 23 356 lbs for the Beneteau Oceanis 46.1 2022. 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 Oceanis 46.1 2022 is rated to a maximum of 80 hp, giving it the larger power ceiling. The Beneteau Idylle 11.50 Fin keel 1983 tops out at 50 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 Idylle 11.50 Fin keel 1983 is Coast Guard rated for 11 passengers, while the Beneteau Oceanis 46.1 2022 is certified for 14. 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 Idylle 11.50 Fin keel 1983 or the Beneteau Oceanis 46.1 2022?
The Beneteau Oceanis 46.1 2022 has the deeper draft at 8,8 ft, versus 4,5 ft for the Beneteau Idylle 11.50 Fin keel 1983. 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 Idylle 11.50 Fin keel 1983 or the Beneteau Oceanis 46.1 2022 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Beneteau Oceanis 46.1 2022 at 23 356 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Beneteau Idylle 11.50 Fin keel 1983 at 11 464 lbs will typically be livelier and more responsive in lighter conditions.
Which is the faster sailboat — the Beneteau Idylle 11.50 Fin keel 1983 or the Beneteau Oceanis 46.1 2022?
Based on rated hull speed, the Beneteau Oceanis 46.1 2022 has an edge at 8,8 knots versus 7,2 knots for the Beneteau Idylle 11.50 Fin keel 1983. 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 wider, and does it affect trailering?
The Beneteau Oceanis 46.1 2022 measures 179" wide, compared to 145" for the Beneteau Idylle 11.50 Fin keel 1983. 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 Idylle 11.50 Fin keel 1983 or the Beneteau Oceanis 46.1 2022?
The Beneteau Oceanis 46.1 2022 has the bigger tank at 53 gallons, versus 21 gallons on the Beneteau Idylle 11.50 Fin keel 1983. That 31-gallon difference translates to roughly 95–159 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Beneteau Idylle 11.50 Fin keel 1983 and Beneteau Oceanis 46.1 2022 from the same manufacturer?
Yes — both the Beneteau Idylle 11.50 Fin keel 1983 and the Beneteau Oceanis 46.1 2022 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.
