Beneteau Flyer 12 2009 vs Beneteau Idylle 11.50 Fin keel 1983 — Same Brand, Different Boat

The Beneteau Flyer 12 2009 vs Beneteau Idylle 11.50 Fin keel 1983 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.

The Beneteau Idylle 11.50 Fin keel 1983 tops out at 50 hp. Engine specs for the Beneteau Flyer 12 2009 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Beneteau Flyer 12 2009 carries 317 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 Flyer 12 2009 is rated for 12 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 Flyer 12 2009 could be the deciding factor.

The Beneteau Idylle 11.50 Fin keel 1983 has a documented displacement of 11 464 lbs. Displacement data wasn't available for the other boat in this comparison.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau Idylle 11.50 Fin keel 1983 draws 4,5 ft, compared to 3,0 ft for the Beneteau Flyer 12 2009. That 1,5-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 has a documented auxiliary engine of 50 hp.

For extended cruising, water capacity matters: the Beneteau Idylle 11.50 Fin keel 1983 carries 106 gallons versus 84 gallons on the Beneteau Flyer 12 2009 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Beneteau Flyer 12 2009 at 41,3 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Idylle 11.50 Fin keel 1983 at 37,8 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.

How many people can each boat hold?
The Beneteau Flyer 12 2009 is Coast Guard rated for 12 passengers, while the Beneteau Idylle 11.50 Fin keel 1983 is certified for 11.
