Beneteau Idylle 11.50 Fin keel 1983 vs Beneteau Swift Trawler 44 2013 — Same Brand, Different Boat

The Beneteau Idylle 11.50 Fin keel 1983 vs Beneteau Swift Trawler 44 2013 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 Swift Trawler 44 2013 measures 45,5 feet overall (2013), giving it roughly 7,7 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 Swift Trawler 44 2013 tips the scales at 23 957 lbs — 12 493 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 50 hp, the Beneteau Idylle 11.50 Fin keel 1983 has a 48-hp advantage over the Beneteau Swift Trawler 44 2013's 2-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 Swift Trawler 44 2013 carries 37 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 Swift Trawler 44 2013 is rated for 13 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 Swift Trawler 44 2013 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.

The Beneteau Idylle 11.50 Fin keel 1983 uses Sloop rigging. The Beneteau Idylle 11.50 Fin keel 1983 has a documented auxiliary engine of 50 hp.

For extended cruising, water capacity matters: the Beneteau Swift Trawler 44 2013 carries 169 gallons versus 106 gallons on the Beneteau Idylle 11.50 Fin keel 1983 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Beneteau Swift Trawler 44 2013 at 45,5 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.

Beneteau Idylle 11.50 Fin keel 1983 vs Beneteau Swift Trawler 44 2013 — Common Questions

Which is the larger boat — the Beneteau Idylle 11.50 Fin keel 1983 or the Beneteau Swift Trawler 44 2013?
The Beneteau Swift Trawler 44 2013 is the longer of the two at 45,5 feet overall. The Beneteau Idylle 11.50 Fin keel 1983 comes in at 37,8 feet, making it roughly 7,7 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 Swift Trawler 44 2013?
For trailering, the Beneteau Idylle 11.50 Fin keel 1983 has the edge at 11 464 lbs dry weight versus 23 957 lbs for the Beneteau Swift Trawler 44 2013. 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 Idylle 11.50 Fin keel 1983 is rated to a maximum of 50 hp, giving it the larger power ceiling. The Beneteau Swift Trawler 44 2013 tops out at 2 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 Swift Trawler 44 2013 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.
What is the draft of the Beneteau Idylle 11.50 Fin keel 1983?
The Beneteau Idylle 11.50 Fin keel 1983 draws 4,5 ft. Draft determines which harbours, anchorages, and haul-out facilities are accessible — always verify with your local marina before purchase.
Which boat is better equipped for long-distance cruising?
For extended passages, fresh water capacity is a key indicator of cruising readiness. The Beneteau Swift Trawler 44 2013 carries 169 gallons of fresh water compared to 106 gallons on the Beneteau Idylle 11.50 Fin keel 1983 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Beneteau Swift Trawler 44 2013 measures 167" 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 Swift Trawler 44 2013?
The Beneteau Swift Trawler 44 2013 has the bigger tank at 37 gallons, versus 21 gallons on the Beneteau Idylle 11.50 Fin keel 1983. That 15-gallon difference translates to roughly 47–79 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 Swift Trawler 44 2013 from the same manufacturer?
Yes — both the Beneteau Idylle 11.50 Fin keel 1983 and the Beneteau Swift Trawler 44 2013 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.
