The Beneteau Cyclades 50.4 2007 vs Beneteau Sense 55 2016 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.
Both boats share a closely matched power ceiling — 110 hp for the Beneteau Cyclades 50.4 2007 and 120 hp for the Beneteau Sense 55 2016. 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 Beneteau Cyclades 50.4 2007 carries 105 gallons versus 11 gallons in the Beneteau Sense 55 2016. 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 Sense 55 2016 is rated for 17 passengers, while the Beneteau Cyclades 50.4 2007 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Sense 55 2016 could be the deciding factor.
The Beneteau Sense 55 2016 has a documented displacement of 39 474 lbs. Displacement data wasn't available for the other boat in this comparison.
Both boats draw a similar depth — 6,5 ft and 7,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
For auxiliary power the Beneteau Sense 55 2016 carries a 120-hp engine against 110 hp on the Beneteau Cyclades 50.4 2007. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
For extended cruising, water capacity matters: the Beneteau Cyclades 50.4 2007 carries 258 gallons versus 169 gallons on the Beneteau Sense 55 2016 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau Sense 55 2016 at 58,4 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau Cyclades 50.4 2007 at 51,3 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
